Characteristics Of Catering Wastewater

The food industry has a wide variety of raw materials, a large amount of wastewater discharge, and significant differences in water quality. The main pollutants in these wastewater include: solid suspension or sediment, proteins, sugars, starch, oils, various chemical and biological additives, and other organic substances. Food wastewater generally does not have significant toxicity, but its high organic content can easily cause eutrophication of water bodies, worsen water quality, and further pollute the environment. Due to differences in raw materials and processes, there are significant differences in the characteristics of wastewater generated. Based on the characteristics of food wastewater, a suitable wastewater treatment process plan is developed and key equipment that meets the requirements is selected.

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.

Process Description

The sewage flows into the regulating tank through a 1-2mm grid, where the quality and quantity of incoming water are regulated; Impurities intercepted by grid deletion need to be cleaned regularly. Next, the sewage in the regulating tank is pumped to the mbr system, where microorganisms decompose and reduce pollutants, including aerobic and anaerobic reaction zones. Impurities that cannot be degraded and activated sludge are separated by membrane components and left in the membrane tank. The water produced by membrane filtration meets the

standards for reuse or discharge

Characteristics of mbr sewage treatment process:

1) The use of unique regular water backwashing, chemical backwashing, and chemical cleaning processes ensures the water production capacity and membrane flux of membrane components.

2) The transmembrane pressure (TMP) is low, usually between 0.01 and 0.06 MPa. It can utilize the siphon principle to produce water without the need for additional suction power, resulting in low system operating costs.

3) The mbr process adopts a combination of hypoxia and aerobic forms. The sewage first enters the anoxic zone, where it decomposes large molecular weight long chain organic matter into easily biodegradable small molecule organic matter. Then, the sewage enters the aerobic zone for organic matter biodegradation, while undergoing biological nitrification

The process is resistant to impact load, has high pollutant removal efficiency, strong nitrification ability, can carry out nitrification and denitrification at the same time, and has the function of nitrogen and phosphorus removal. It is very suitable for the treatment of dispersed sewage such as laundry wastewater. The effluent can be reused or discharged directly to the standard, which can meet the needs of users for water quality.

Membrane bioreactor pool of trachea were divided into two road, all the way to the surrounding aeration activated sludge, the other all the way to aeration membrane module of diaphragm, the advantage for the scouring force made by membrane aeration diaphragm slapping each other, so that we can shake off attached calcification on the surface of the sludge in the membrane pores, the membrane flux greatly improve extend the service life of the membrane, which reduces the running cost.

MBR membrane bioreactors have been widely used in wastewater treatment due to their advantages such as good effluent quality, small footprint, and short residence time. The MBR membrane module is an important core component that has good retention performance for the large amount of pollutants contained in food industry processing wastewater. It can intercept substances that cannot meet the standards in traditional processes, making the effluent meet the standards and can be directly reused.
