Description

Food and drink waste water handles retracting device and method
Technical field:
The present invention relates to industrial wastewater treatment device and technology field, specifically a kind of non-secondary pollution, into This rational food and drink waste water processing retracting device and method.
Background technology:
With flourishing for catering industry, the discharge capacity of food and drink waste water is increasing, it has also become a weight of town sewage Source is wanted, its discharge capacity accounts for the 3% of municipal wastewater discharge capacity.But food and drink waste water COD and BOD5Contribution margin but to have reached 1/3 left It is right.This is because the high organic content of food and drink waste water, composition is sufficiently complex, mainly there is food fiber, starch, fat, dynamic plant Thing grease, all kinds of seasonings, detergent and protein etc..Therefore, the below standard discharge of food and drink waste water can not only increase municipal wastewater The load of processing, moreover, certain pollution will be produced to surrounding city river;In addition, the swill in food and drink waste water easily blocks up Sewer and urban sewage pipe are filled in, and distributes niff, under the conditions of long term hypoxia, food and drink waste water also easily arrange by corrosion Waterpipe.
Food and drink waste water is caused leftover and water during food and drink, with starch, food fiber class, tallow The organic matters such as fat class are main component, have high organic content, pH excursions are big, moisture content is high, perishable fermentation is smelly etc. Feature, it has also become one of city pollution sources of greatest concern.At present, food and drink waste water and unprocessed and be directly discharged into urban sewage Pipeline.Shown according to the testing result to China developed regions such as ground such as Guangzhou, Shanghai food and drink waste water, COD indexs in food and drink waste water For 1000mg/L or so, far above country《Integrated wastewater discharge standard》(GB8978-1996) emission level specified in, this nothing Doubt the processing load for adding municipal sewage plant.In addition, the direct discharge of food and drink waste water has an effect on urban drainage pipe network Discharge capacity, causes body eutrophication etc., serious threat environment and human health.Therefore, the improvement to food and drink waste water becomes Urgent problem.
At present, the processing for food and drink waste water mainly has bioanalysis (SBR methods, magnetic powder reinforcing activated sludge process, catalytic oxidation Method, MBR methods), gravity and centrifugal separation, Bubble-floating Method, absorption method, electrochemical process (electrocoagulation, light electrolysis-electrolysis, pulse Electric flocculation method), the methods of Coagulation Method, but more there are dosing, have the threat of secondary pollution, sludge quantity it is big, it is difficult or Filler easily blocks, and treatment effect fluctuates the problems such as larger with water quality index such as wastewater pHs.
The content of the invention:
The present invention is directed to shortcoming and defect existing in the prior art, it is proposed that a kind of non-secondary pollution, meal of reasonable cost Drink waste water treatment and reclamation device and method.
The present invention can be reached by following measures:
A kind of food and drink waste water handles retracting device, it is characterised in that equipped with for separating bulk foreign matter and sewage in waste water Separate tank, the pulverizer for being crushed to the bulk foreign matter isolated, the biography for foreign matter after crushing to be put into biochemistry pool Send mechanism, the sedimentation basin for carrying out precipitation filtering to waste water after separation, for carrying out the smelly of oxygenolysis to filtrate after precipitation Oxygen oxygenation machanism, for after being decomposed to ozone oxidation sewage carry out Air Exposure aeration tank, for being decomposed to biochemistry pool after Sewage carries out the filtering precipitation mechanism of filtration treatment.
Filling can cut grease and the aerobic microbiological of organic matter in biochemistry pool of the present invention, be equipped with biochemistry pool with The water distributor that sewage inlet is connected, is additionally provided with jet aerator, sewage (waste water) recirculating pump, microorganism sludge reflux mechanism, in work During work, the aerator in biochemistry pool pours air into sewage, and circulates water distribution, cloth by sewage (waste water) recirculating pump and water distributor Hydrophone includes supervisor and with being responsible for the more than two branch pipes being connected, supervisor and the water distribution that flat opening is equipped with branch pipe Hole, water distributor circulation water distribution can be such that grease in sewage and other organic matters are fully contacted with anaerobe.
The exhaust gear that ozone oxidation mechanism of the present invention includes ozone generator, is connected with ozone generator is smelly After oxygen is passed into sewage, energy oxygenolysis Organic substance in water is most strong to the oxidability of fiber, alkenes compounds, secondly Amine and hydrocarbon double bond are thirdly three keys of alkynes for compound, carbocyclic ring heterocyclic compound, sulfide, phosphide etc., ozone pair The singly-bound oxidability of alcohol, aldehyde, ether and nytron is weaker.Organic matter through ozonization, the increase of its biodegradable;It is smelly Oxygen can also remove stench in, by bacterial destruction, and neutralizing in the short time, decomposing poison gas.
The multistage filtering grid or more set gradually along waste water stream through direction is equipped with filtering precipitation mechanism of the present invention Level filter screen, crosses filter cake and is discharged by waste residue elevator, the compound discharge standard of waste water can be discharged directly or as garden Woods is irrigated.
The invention also provides a kind of food and drink waste water handles recovery method, it is characterised in that comprises the following steps:
Step 1:Food and drink waste water is sent into separate tank, bulk is isolated by filtering grid or filter screen in separate tank Foreign matter, and bulk foreign matter is sent into pulverizer and is crushed, waste water after filtering is discharged into sedimentation basin;
Step 2:By the waste water after filtering after sedimentation basin precipitates filtering, sewage is aoxidized by ozone oxidation mechanism Handle, the organic macromolecule material in sewage is broken down into small molecule structure material, and kills except harmful worm's ovum in waste water, carefully Bacterium, then send waste water into aeration tank;
Step 3:Waste water under the auxiliary through aerator, stops 2-3h, is admitted to biochemistry pool in aeration tank;
Step 4:Aerobic microbiological is filled with biochemistry pool, while the foreign matter in step 1 after crushing is also put into biochemistry pool, Under the action of sewage (waste water) recirculating pump and water distributor, sewage fully circulates in biochemistry pool, fully anti-with aerobic microbiological Should, pass through debirs in microbial degradation biochemistry pool;
Step 5:Waste water after biochemistry pool reaction is discharged into filtering precipitation mechanism, and after filtered precipitation, precipitation waste residue can be with Recycling is used as fertilizer, and filtering gained liquid can be discharged directly or as gardens agricultural irrigation water.
Compared with prior art, the present invention acidic materials or alkaline matter need not be added in sewage disposal process to dirt Water is adjusted, and does not produce secondary pollution, and waste residue and waste water can recycle after processing, have cost is low, working stability, The advantages that environment-protection low-consumption.
