Summary:
　　Food wastewater including alcohol, beer, gourmet powder, starch, lactose, citric acid, vegetable processing and various kinds of soft drinks to remove waste water processing, if not timely processing waste water will cause great pollution to the environment.
　　The main pollutant food wastewater are:
　　1. Floating solids in the wastewater, such as vegetable, fruit, meat and poultry feathers, etc.;
　　2. The suspended substance in waste water with oil, protein, starch, colloidal substance, etc.;
　　3. The dissolved in wastewater of acid, alkali, salt, sugar, etc. :
　　4. The raw materials with mud, sand and other organic matter, etc.;
　　5. Pathogenic bacteria such as poison.Food industry wastewater is characterized by high organic matter and suspended solids content, easy to corruption, there is no greater toxicity.The harm is mainly the eutrophication of water bodies, so that the cause of aquatic animals and fish, prompting subaqueous sedimentary organic produce odor, deteriorating water quality, the environmental pollution.
　　The food industry has the characteristics of large scale and a lot of sewage, and sewage often contains a large number of carbohydrate, protein, and N, P compound microbial bacteria.So food hydraulic load of wastewater and organic load is higher, the environmental pollution is very strong, especially can cause eutrophication of water body, destruction of water self-purification ability.If direct emissions, water body pollution degree, was palpable.
　　Our company combined with years of experience of the pollution treatment, the tireless efforts of many designers and engineers, production integration of sewage treatment equipment, sewage disposal in food has made good benefit.Are presented as follows:

　　Equipment parameters:
　　Product name: food wastewater treatment equipment
　　Model: zl - spws001
　　Sewage quantity: 1-1000 (m3 / h)
　　Ozone dosage: 1-1000 (g/h)
　　Air quantity: 1-1000 (m3 / min)
　　Aerator power: 0.75 (kw)
　　Pump power: 0.75 (kw)
　　Processing custom:

　　Basic principles:
　　Pool material made with high and new technology, make the sewage treatment equipment of whole set to advanced technology, reasonable configuration, excellent performance, good corrosion resistance, convenient maintenance, beautiful appearance.Pool material according to different reactor in the form of anticorrosive prefabricated steel plate, special sealing material leak proof, this kind of prefabricated steel plate form a protective layer can not only prevent the corrosion of tank, and has the function of strong acid, strong alkali resistance.Short build period;Corrosion resistance is strong;The sewage plant expansion to less investment and put into production soon.

　　Technological process:
　　Adjust the pool - gas fugitive dust fall pool - YanYangChi - biological aerobic pool - the second pond - filter - water recycling pool

　　Process description:
　　The design of the equipment is mainly for domestic sewage and industrial organic wastewater treatment.The main processing method is to use the relatively mature contact oxidation pool biochemical treatment technology.Water quality design parameters according to the sewage water is 250 mg/L BOD5, effluent BOD5 calculation for 20 mg/L.At the beginning of a total of seven parts: pond;Anaerobic pool;Contact oxidation pool;The second pond;Pool disinfection, disinfection device;The sludge pool;The wind of computer room.
　　The pond at the beginning: the early pond for vertical flow sedimentation tank, sewage in the rising velocity of settling basin is 0.3 ~ 0.4 mm/SEC, settle sludge to sludge pools.SFW - 5 pond, early and the following equipment is not set.
　　2. Oxygen pool: oxygen pool Settings for nitrogen treatment, pool YDT stereo elastic filler is installed inside, as the carrier of denitrifying bacteria, nitrifying back into nitrate in liquid ammonia and acid state oxygen in under the action of denitrifying bacteria, reduction of nitrogen, achieve the goal of denitrification, anaerobic pool effective retention time was 2.5 ~ 3.5 h, dissolved oxygen control in 0.5 mg/L or less.
　　3. The contact oxidation pool: complete wastewater biochemical treatment, to touch the touch the three levels, the residence time is 8 h, (enhanced equipment contact oxidation time up to 8 ~ 12 h) novel packing for elastic filler, conjunctiva, non-clogging, gas-water contact oxidation pool than about 15:1.
　　4. The second pond: biochemical sewage flows into the second pond, the pond for the vertical sedimentation precipitation, surface load as < m2 of 1.0 m3 / h, dredge up to the sludge pool.
　　5. Pool disinfection, sterilization device: disinfection pool according to the specification: "TJ14-74" standard for not less than 30 minutes, and if the hospital sewage, disinfection pool can increase the residence time to 1 ~ 1.5 h.
　　6. Contact disinfection using solid chlorine tablets dissolve ways of disinfection disinfection device can be changed according to the size of the water yield is not following the dosage, achieve water add more medicine, less water less dosing, the purpose of need other disinfection device can be made separately.

　　The key technologies:
　　The key to the high and new technology is:
　　1. The overall design of the reasonable structure of the reactor tank.
　　2. Prepare special anticorrosive coating process.
　　3. Advanced processing technology.
