Characteristics Of Catering Wastewater

Restaurant waste water refers to the restaurant waste water is the residue and waste generated by catering industry and the canteen, and another refers to the oily slops generated by restaurants and guesthouses, including rice washing water, rice soup, leftovers, fish bones, melon and vegetable skin.

The main components of food and beverage wastewater are residual food and water, starch, food fiber, animal fat and other organic compounds as the main components, with high nutrient composition, high moisture content, high oil and salt content, perishable fermentation odor and other characteristics. If it is collected, transported and disposed together with household garbage, it will seriously affect the city environment and residents' life, and also affect the disposal effect of household garbage. In addition, food waste contains a large number of organic matter, its nutrition is comprehensive and rich, as long as through the appropriate treatment technology, can make food waste water to be fully "resource" utilization.

Due to its high organic content and high BOD/COD value, catering wastewater is a kind of highly concentrated organic industrial wastewater with good biochemical properties. With many years of practical experience, past and combining domestic and foreign similar wastewater treatment process and effect, to biochemical treatment should be adopted as the main body and membrane filtration process routes, specific to the original catering wastewater by anaerobic pretreatment, to improve the efficiency of wastewater treatment, save the project cost, reduce the processing cost, and then to aerobic treatment by membrane filtration, To meet emissions requirements. In order to improve the treatment effect, the main process of aerobic treatment is easy to adopt the new wastewater treatment process of advanced technology, simple process flow, stable treatment effect and strong impact load resistance, hydrolytic acidification + contact oxidation treatment +MBR membrane process.

1. Physical and chemical treatment

• Drain well

Because waste water contains animal and vegetable oil, fat. The effective treatment method of oil is oil isolation and air flotation. We choose gravity separation oil trap to coarsely granulate oil, that is, the oil trap is filled with oil-hydrophilic and hydrophobic materials to gather oil particles. When the oil particles become large, they float up because the specific gravity is lighter than that of water, and then the floating oil is removed by fishing.

• The flotation

Flotation is the process of chemical demulsification, coagulation and removal of dispersed oil and part of floating oil by air flotation. According to the characteristics of wastewater in this project, it is obvious that the flotation function can not be well played if only oil is removed by flotation method. Through the experiment, after adjusting the pH and coagulation reaction, the suspended solids in the wastewater are lighter, and the precipitation time is longer, so flotation can achieve twice the result with half the effort.

2. Biochemical treatment of food wastewater

After air flotation by coagulation, the biodegradability of the wastewater can be cleared. In addition to the addition of biological agents, the microbial method is used to treat this kind of wastewater. After analysis and comparison, we recommend the selection of floatation, anaerobic and aerobic respectively

• U/A/S/B reactor

It can adapt to high concentration wastewater, strong impact load resistance, good granular sludge character, and can adapt to S food wastewater treatment after intensive inoculation.

• Aerobic process

The main removal objects of aerobic biological treatment are dissolved and colloidal organic pollutants in sewage. Through the metabolism of microorganisms to be transformed and stabilized, to achieve harmless.

Main advantages of biological contact oxidation:

(1) Due to the large specific surface area of fillers and good oxygenation conditions in the tank, the biomass per unit volume in the oxidation tank is higher than that in the activated sludge aeration tank and biological filter tank, which can achieve a higher volume load;

(2) There are a large number of highly active microorganisms on the fillers of the contact oxidation pool, which can quickly adsorb, synthesize and oxidize organic matter in sewage. Because the aging biofilm on the filler will constantly fall off, so that the biofilm attached to the filler can maintain high activity for a long time, so the sludge reflux is not needed, the sludge yield is low, no sludge bulking, and the operation is stable

(3) High oxygen utilization rate;

(4) Compared with activated sludge process and oxidation ditch process, although the volume load of contact process is higher, the sludge yield is lower, mainly because: a. The microbial chain in the oxidation pool is relatively complete and stable. b. The endogenous respiration of microorganisms is more complete, and the synthetic substances are further oxidized; c. There are anoxic and anaerobic zones in the biological filler, which can partially decompose and transform organic matter.
