Abstract
The invention relates to the technical field of sewage purification treatment, in particular to a catering sewage treatment method with high treatment efficiency and good purification effect. The method comprises the following steps: step 1: enabling catering sewage with grease materials to pass through a filter screen to filter solid wastes with relatively large size; step 2, sending the sewage passing through the filter screen to a microbial fermentation container for fully reacting, and then sending the obtained mixture to a settling pond; step 3, adding a flocculating agent to the settling pond; step 4, sending a mixed solution after flocculation treatment to an anaerobic reaction device; step 5, draining the solution after anaerobic treatment to a secondary settling pond, adding a sewage treatment agent to the secondary settling pond for fully reacting, and finally draining through the filter screen. Compared with the prior art, the treatment method is simple, convenient and easy to operate, can effectively reduce the content of the grease materials in the catering waste water, and prevents plenty of grease materials from adhering to the inner part of a drainage pipeline to rot and cause germs.
Description
Technical field:
The present invention relates to the dirty water decontamination handles technical field, specifically the food and drink class sewage water treatment method of high, the good purification of a kind of processing efficiency.
Background technology:
Along with social development and the raising of living standards of the people, catering industry is become increasingly prosperous.The sewage of catering industry discharge generally contains grease, and the residual chemical substance of washing composition of cleaning grease, if this type of sewage directly discharges, can cause environmental pollution, because the oil material existing in this type of sewage easily attaches on drainage pipeline, long-term accumulation easily causes line clogging.The waste water of food and beverage enterprise and businessman's generation is general direct at present enters municipal sewage plant by water exhaust system, in municipal sewage plant, be provided with biochemical treatment system, by microorganism, the heavy metal in waste water, nitrogen, phosphorus and other objectionable impuritiess are decomposed, but the oil material containing in food and drink class sewage easily makes the microbial death in biochemical treatment system, cause that sewage treating efficiency is low, decontamination effect improving is poor, discharge is not up to standard.
Summary of the invention:
The present invention is directed to the shortcoming and defect that prior art exists, proposed that a kind of processing efficiency is high, the food and drink class sewage water treatment method of good purification.
The present invention reaches by following measures:
A kind of food and drink class sewage water treatment method, is characterized in that comprising the following steps:
Step 1: make the food and drink class sewage that contains grease material by filter screen, the solid refuse that filtering volume is larger;
Step 2: will send into microorganism fermenting container by the sewage after filter screen, be provided with aerobic microbiological in microorganism fermenting container, pass into air in microorganism fermenting container, and stir, fully after reflection, mixture after reaction is sent into settling tank;
Step 3: add flocculation agent in settling tank, the mixture after flocculation treatment passes through filter screen;
Step 4: the mixing solutions after flocculation treatment is sent into anaerobic reaction device, be provided with anaerobic sludge in anaerobic reaction device, be further processed for the objectionable impurities to mixing solutions;
Step 5: the solution through anaerobic treatment is discharged into secondary sedimentation basins, adds sewage-treating agent in secondary sedimentation basins, fully reaction, discharges through filter screen.
Described in step 5 of the present invention, sewage-treating agent comprises following component: water glass 4-12 part, magnesium chloride 1-6 part, iron(ic) chloride 0.5-1.5 part, polymerize aluminum chloride 0.2-1.2 part, cationic-type polyacrylamide 0.2-2.5 part; When interpolation, the weight ratio of sewage-treating agent and sewage is 1: 6500-1: 25000.
Step 2 time length of the present invention is 7-10 hour, and makes solution temperature in microorganism fermenting container remain on 20-40 DEG C.
Described in step 3 of the present invention, flocculation agent adopts biological flocculant, the objectionable impurities in sewage fully can be discharged by the processing of biological flocculant.
In step 5 of the present invention, also comprise sewage-treating agent mixture after treatment is carried out to adsorption treatment, add sorbent material, sorbent material can adopt gac, and the sewage after adsorption treatment is finally discharged after net filtration after filtration.
Compared with prior art, treatment process is simple and easy to operate in the present invention, can effectively reduce the content of grease material in food and drink class waste water, avoids a large amount of grease materials to stick to rotten breed bacteria in drainage pipeline.
Embodiment:
Below in conjunction with embodiment, the present invention is further illustrated.
A kind of food and drink class sewage water treatment method that the present invention proposes, is characterized in that comprising:
Step 1: make the food and drink class sewage that contains grease material by filter screen, the solid refuse that filtering volume is larger;
Step 2: will send into microorganism fermenting container by the sewage after filter screen, in microorganism fermenting container, be provided with aerobic microbiological, in microorganism fermenting container, pass into air, and stir, the continuous time is 7-10 hour, and make solution temperature in microorganism fermenting container remain on 20-40 DEG C, fully after reflection, mixture after reaction is sent into settling tank;
Step 3: add flocculation agent in settling tank, the mixture after flocculation treatment passes through filter screen;
Step 4: the mixing solutions after flocculation treatment is sent into anaerobic reaction device, be provided with anaerobic sludge in anaerobic reaction device, be further processed for the objectionable impurities to mixing solutions;
Step 5: the solution through anaerobic treatment is discharged into secondary sedimentation basins, in secondary sedimentation basins, add sewage-treating agent, fully reaction, discharge through filter screen, described sewage-treating agent comprises following component: water glass 4-12 part, magnesium chloride 1-6 part, iron(ic) chloride 0.5-1.5 part, polymerize aluminum chloride 0.2-1.2 part, cationic-type polyacrylamide 0.2-2.5 part; When interpolation, the weight ratio of sewage-treating agent and sewage is 1: 6500-1: 25000.
In step 5 of the present invention, also comprise sewage-treating agent mixture after treatment is carried out to adsorption treatment, add sorbent material, sorbent material can adopt gac, and the sewage after adsorption treatment is finally discharged after net filtration after filtration.
Compared with prior art, treatment process is simple and easy to operate in the present invention, can effectively reduce the content of grease material in food and drink class waste water, avoids a large amount of grease materials to stick to rotten breed bacteria in drainage pipeline.
