The automatic control of sewage treatment equipment in Hebi Beverage Plant does not need to be monitored. The main pollutant of beverage wastewater is COD. According to different beverage types, the concentration of organic matter in beverage wastewater can be divided into high concentration, medium concentration and low concentration. For example, the COD of dairy beverage wastewater is higher, the COD of acid-free carbonated beverage wastewater is medium, and the COD of tea beverage is lower. Beverage wastewater belongs to wastewater with better biochemical properties.
Beverage wastewater treatment program: process flow

Hebi Beverage Plant does not need to take care of the automatic control of sewage treatment equipment. Manager Liu: 185,388,69535 Wei Xintong No. <br /> The main pollutant of beverage wastewater is COD. According to different beverage types, the concentration of organic matter in beverage wastewater can be divided into high concentration, medium concentration and low concentration. For example, the COD of dairy beverage wastewater is high, the COD of acid-free carbonated beverage wastewater is medium, and the COD of tea beverages is low. Beverage wastewater belongs to wastewater with better biochemical properties.
Beverage wastewater treatment scheme: Process flow The typical process flow is as follows:
Wastewater → collection → multi-stage facultative, aerobic biological treatment (A / 0) n → standard discharge (A / 0) n process one: there are soft fiber fillers in the pool to improve the distribution of microorganisms and increase biomass; The second is to divide the wastewater treatment process into several different concentration sections, and each concentration section cultivates microorganisms suitable for the living conditions of the section, giving full play to the activity of the microorganisms, and degrading organic matter to the greatest extent. The metabolic activities of sex bacteria transform large molecules, insoluble and difficult to degrade organic matter into small molecules, easily soluble and degradable organic matter. At the same time, facultative bacteria have the characteristics of strong shock resistance due to their short generation time and fast reproduction. Therefore, the facultative segment can create favorable biochemical conditions for the aerobic segment. Due to the innovative nature of the (A / 0) n process, this process has the advantages of stable operation, high treatment efficiency, and low energy consumption when applied to organic wastewater treatment. Practice has proved that (A / 0) n process biological treatment rate can be increased by 20-30% and energy consumption can be saved by 20-30% under the same sewage concentration and same tank capacity. After biochemical treatment, the sewage is coagulated and precipitated by adding drugs to remove dead microorganisms and suspended matter, so that the water is clarified and discharged.
The process flow of wastewater treatment in beverage plant is as follows:
The main control parameters are:
The ICEAS method is a highly efficient water treatment method that has been widely used in recent years. It is different from the traditional activated sludge method in that it integrates the aeration tank and the sedimentation tank, and the treatment is in an intermittent circulation state, which is an improvement. SBR method. The ICEAS method is used to treat beverage production wastewater, which makes the removal rate of COD and BOD in the wastewater reach over 90%. The process has four characteristics: one is an improved batch processing system for continuous water discharge and water discharge; the second is the combination of the reaction tank and the sedimentation tank, which reduces the construction cost; and the third is that during the sedimentation and water discharge stages, the activated sludge is in the During the endogenous respiration period, the sludge production efficiency is low. Fourth, it is easy to settle the activated sludge in a completely stationary state.
UASB2 aerobic process for the treatment of carbonated beverage wastewater. Beverage wastewater treatment scheme: The process of wastewater treatment uses an anaerobic + aerobic system to remove organic matter in the wastewater.
The wastewater from the beverage factory is discharged from the workshop and discharged into the regulating tank. Then, the wastewater passes through a hydraulic solid-liquid separator to remove most of the suspended solids in the wastewater. The wastewater from the conditioning tank is pumped to the acidification tank and the upflow anaerobic sludge bed reactor (UASB). Its flow is controlled by a microcomputer. Organic matter is first decomposed into organic acids and then into methane and carbon dioxide. A series of three-phase separators are set on the top of the reactor to effectively separate methane gas, sludge and treated wastewater. This three-phase separator can effectively trap all useful methane. The collected methane gas can be used as boiler fuel. In the system, there is also a burner for processing unused methane gas. The anaerobic wastewater was post-treated by a conventional activated sludge treatment system to reduce the COD to 20 mg / L. The treated wastewater is discharged into a watercourse.
Beverage wastewater treatment scheme: The adjustment tank commonly used in the adjustment tanks of basic structures, the inlet water is gravity flow, and the effluent is pumped up by the pump. In addition, the intermittent discharge liquid with high alkalinity should be stored separately and then quantitatively discharged into the adjustment tank. Drugs required to reduce p H regulation.
The acidification tank is mainly used by acid-producing bacteria to hydrolyze and acidify various complex macromolecular organic compounds into small molecular fatty acids, alcohols, aldehydes, hydrogen and other substances. The acidification tank has a volume of 500 m3, which is a concrete structure. Dimensions: length × width × depth = 1318 m × 713 m × 515 m; hydraulic retention time 6 h; volume load 25 to 50 kg / (m31 d); mixer power 3kW (610 W / m3).
Upflow anaerobic sludge bed reactor (UASB) Upflow anaerobic sludge bed reactor is a compact anaerobic reactor that integrates biological reaction and sedimentation. It is mainly composed of 5 parts: inlet water distribution system, reaction zone, three-phase separator, air chamber (also known as air collecting hood), and treated water discharge system. Compared with other types of anaerobic reactors, the upflow anaerobic sludge bed has a series of advantages, including: (1) the biomass in the sludge bed is large, and the reduced concentration can be calculated to 20-30 g / L; (2) The volumetric load rate is high. Under medium temperature fermentation conditions, it can generally reach about 10 kg / (m3 • d), and even up to 15-40 kg / (m3 • d). The hydraulic retention time of wastewater in the reactor It is short, so the required tank capacity is greatly reduced; (3) The equipment is simple and convenient to operate.There is no need to set up a sedimentation tank and sludge return device, no filling is required, and no mechanical stirring device is required in the reaction zone. Low, easy to manage, and there is no blockage. The designed COD volume load is 6 kg / (m3 • d), and the volume of the UASB reaction cell is 667 m3. The designed removal rate reached 90% after anaerobic treatment, that is, the COD concentration after treatment was 200 mg / L, the BOD concentration was 135mg / L, and the sludge generation amount was 0104 kg / kg, so the total sludge production was 144 kg / d. The biogas produced is approximately 1440 m3 / d (containing 75% methane).
After the activated sludge aerobic system is treated by the anaerobic system, 80% to 90% of the organic matter is removed from the sewage. To ensure that the national first-level discharge standards can be reached, the anaerobic sewage is treated by a traditional activated sludge treatment system Reduce the COD to about 20 mg / L. Residual sludge from the activated sludge system will be returned to the acidification tank and other sewage will be sent to the anaerobic system for digestion. BOD contained 270 kg / d, the designed F / M ratio was 013 kg / (kg • d), and the concentration of MLVSS was 2250 mg / L. The volume of the aeration tank is 400 m3. Two aeration tanks are used, and the oxygen demand is 540 kg / d. The aeration head uses a standard oxygen transfer rate (depth 412 m) of 50186 g / (m3 • m), and the number of aeration heads required according to 8 m3 / (h • m) is 56 m. Use 80 aeration heads for safety reasons. The required air volume for aeration is 44204 m3 / h, so two 240 m3 / h (515 kW) blowers are selected. The remaining sludge volume was 55 kg / d, and the sludge moisture content was 9912%.
The sedimentation tank is calculated based on a flow of 2000 m3 / d, a surface load of 110 m3 / (m2 • h), and a central tube flow rate of 108 m / h. The diameter of the pool is 1013 m.
Beverage wastewater treatment scheme: System characteristics The anaerobic process effluent partial reflux acidifier has a high VFA concentration, low alkalinity and p H, and methanogens are suitable for growing in environments where p H is neutral or slightly alkaline. If the effluent from the acid generator directly enters the methanator, it is difficult for methanogens in the methanator to obtain optimal growth conditions, and the treatment efficiency of the reactor is bound to be affected. Therefore, it is an economical operation method to return the effluent of the methanator with higher pH and alkalinity, mix it with the acidifier effluent, and then enter the methanator.
The three groups of activated sludge systems are designed in parallel to provide a large degree of freedom in operation, so that the operator can adjust the appropriate operation mode according to the site conditions. In the system, the remaining sludge can be pumped to the acidification tank and the sewage enters the UASB for digestion. The UASB only needs to discharge the sludge once a year. The sludge is stable and its moisture content is about 85% to 90%. To compost it, there is no need to add sludge dewatering equipment to the system. The sludge can be stored for a longer period of time for use in debugging other systems.
Inflow water heating (used in winter) In winter, the low temperature of the sewage is 10 ℃, and the low temperature of the anaerobic tank is 24 ℃. Therefore, a waste heat recovery system must be added to the system to raise the temperature of the sewage after anaerobic. The steam demand is 1290 kg / h.
