Abstract
The invention discloses a method for processing food product factory waste water. The method comprises the following steps: firstly, waste water flows into an anaerobic fermentation tank and anaerobic fermentation is carried out; secondly, the waste water after anaerobic fermentation is transferred to an aerobic fermentation tank and aerobic fermentation is carried out; thirdly, the waste water after fermentation in the second step is subjected to precipitation separation in a precipitation tank, the supernatant is transferred to a disinfection tank, is subjected to disinfection processing and then is discharged; fourthly, residues in the precipitation tank are collected regularly, and the residues are subjected to high temperature disinfection and then are employed as a forage. The method can achieve innoxious disposal, resource-recovering and reduction of food product factory waste water, and has advantages of simple technology and strong controllability.
Description
Technical field
The invention belongs to sewage treatment area, be specifically related to the method for a kind of food processing plant waste water.
Background technology
Because food variety is various, raw material sources are extensive, and food industrial wastewater has suspended substance, fat content is high, heavy metal ion is many, COD and BOD numerical value is large, and who knows and water yield vary within wide limits, nitrogen, phosphorus compound content are high, in some cases water temperature also comparatively high.Sewage treatment process is divided into coagulation, second-stage treatment and tertiary treatment.For foodstuffs industry sewage, coagulation is generally adopt solid-liquid separation technique to remove suspended substance in sewage and floating matter; Second-stage treatment is main processes, and the general biologic treating technique that adopts removes the toxic substances such as Organic substance in water, generally adopts the technology such as membrane processing method, strong oxidizer to be evolved further by sewage.
Food wastewater can produce the animals and plants waste produced in mud, waste oil, spent acid, salkali waste, the course of processing in treating processes also should carry out harmless treatment.
Food processing wastewater is mainly from three production workshop sections.
(1) raw material cleaning workshop section.A large amount of sand foreign material, leaf, skin, squama, meat, plumage, hair etc. enter in waste water, make in waste water containing a large amount of suspended substance.
(2) production workshop section.In raw material, a lot of composition can not all utilize in the course of processing, does not utilize part to enter waste water, makes waste water contain large amount of organic.
(3) forming station.For increasing food color, extending preservation period, employing various foodstuff additive, a part runs off and enters waste water, makes waste water complex chemical composition.
The water quantity and quality characteristic of food processing wastewater is mainly reflected in 6 aspects:
(1) produce with seasonal variation, the waste water quality water yield is also with seasonal variation.
(2) wastewater flow rate is not of uniform size, and foodstuffs industry is from the small-scale of household industry to various integrated mill, and range of product is various, and the difference such as its raw material, technique, scale are very large, and wastewater flow rate is not from several m3/d to thousands of m3/d etc.
(3) in food industrial wastewater, biodegradable component is many, for normal food industry, because raw material sources are in nature organic substance, composition in its waste water is also based on natural organic matter matter, not containing toxic substance, therefore biodegradable is good, and its BOD5/COD is up to 0.84.
(4) high-concentration waste water is many.
(5) contain various microorganism in waste water, comprise pathogenic microorganism, waste water is easily corrupt smelly.
(6) in waste water, the content of nitrogen and phosphorous is high.
Select food sewage effluent treatment process, not only will consider the composition of objectionable impurities in sewage, and will understand the instantaneous variation situation of effluent sewerage water quality, the water yield, these are all very important to selection sewage treatment process, equipment and operational management in the future.
Summary of the invention
The object of the invention is to provide the method for a kind of food processing plant waste water.
Technical scheme of the present invention is: the method for a kind of food processing plant waste water, is characterized in that, comprise the steps:
(1) waste water is flowed in anaerobically fermenting pond carry out anaerobically fermenting;
(2) waste water after anaerobically fermenting is proceeded in aerobic fermentation pond carry out aerobic fermentation;
(3) the waste water precipitate and separate in settling tank after step (2) being fermented, supernatant liquor proceeds in sterilization pool and discharges after disinfection;
(4) residue of periodic collection settling tank, using after residue high-temperature sterilization as feed.
Further, the method for sterilization is in step (3): filtered by the part water in sterilization pool, then the water after filtering is used for chlorine dioxide generator with water, then water backflow such as the sterilization pool containing dioxide peroxide is used for the sterilization of sterilization pool.
Further, the method for filtration is: adopt quartz filter and activated charcoal filter coupling to filter, water first passes through activated charcoal filter again after quartz filter.
The present invention compared with prior art tool has the following advantages:
Method of the present invention can realize innoxious, resource utilization, the minimizing of food plant wastewater, has the advantage that technique is simple, controllability is strong.
