Abstract
The invention relates to the technical field of environmental protection, and particularly relates to a treatment method for wastewater generated in milk production process. The treatment method of milk production wastewater comprises the steps of: filtering production wastewater with a geogrid, then sequentially passing through an adjusting tank, a hydrolysis and acidification tank, a biological contact oxidation tank, an inclined tube sedimentation tank, a middle water tank, a multi-medium filter and a clean water tank, and discharging the processed wastewater after the processed wastewater reaches standard, wherein NaOH is added to the adjusting tank; impurities are removed by floatation in the hydrolysis and acidification tank; and PAC (polyaluminum chloride) is added to the inclined tube sedimentation tank. The treatment method has the advantages of simple structure, good wastewater treatment effect and short treatment time.
Description
Technical field
The present invention relates to environmental protection technical field, the method for wastewater treatment in the esp milk production process.
Background technology
The product of milk processing plant is a fresh milk.Milk-product such as sour milk; Its waste discharge mainly is the washing water of milk container and processor, and contained organic matter is mainly nutritive substances such as carbohydrate, protein, fat in the waste water, does not have toxicity; If but do not handle will turn sour smelly, thereby produce a large amount of bacterium contaminate environment.
Summary of the invention
The technical problem that the present invention will solve is: overcome the deficiency in the prior art, a kind of milk-producing method of wastewater treatment of simple in structure, good waste water treatment effect is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of milk-producing method of wastewater treatment; Factory effluent passes through equalizing tank, hydrolysis acidification pool, biological contact oxidation pond, tube settler, intermediate pool, more medium filter and clean water basin successively after putting down worker's grid filtration, last qualified discharge, and described equalizing tank need drop into NaOH; Hydrolysis acidification pool is floating with Impurity removal through vapour; Described tube settler drops into PAC, with the fine impurities conglomerate, makes its sedimentation.
Equalizing tank of the present invention and biological contact oxidation pond are through the gas blower bubbling air.
The sludge settling of intermediate pool of the present invention is to sludge thickener, and outward transport is disposed through pressure filter.
A part of waste water of more medium filter of the present invention gets into equalizing tank through backwash water.
More medium filter of the present invention links to each other through recoil pump with clean water basin.
The invention has the beneficial effects as follows: the present invention is simple in structure, good waste water treatment effect, and the treatment time is short.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a schema of the present invention.
Embodiment
Combine accompanying drawing and preferred embodiment that the present invention is further described now.These accompanying drawings are the synoptic diagram of simplification, substruction of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of milk-producing method of wastewater treatment; Factory effluent passes through equalizing tank, hydrolysis acidification pool, biological contact oxidation pond, tube settler, intermediate pool, more medium filter and clean water basin successively after putting down worker's grid filtration; Last qualified discharge; Described equalizing tank need drop into NaOH, and hydrolysis acidification pool is floating with Impurity removal through vapour, and described tube settler drops into PAC; Described equalizing tank and biological contact oxidation pond are through the gas blower bubbling air; The sludge settling of described intermediate pool is to sludge thickener, and outward transport is disposed through pressure filter; A part of waste water of described more medium filter gets into equalizing tank through backwash water; Described more medium filter links to each other through recoil pump with clean water basin.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
