Problems solved by technology

Catering wastewater has the characteristics of high BOD and COD concentration, high oil content, and large discharge. At the same time, because there are relatively few toxic substances in this type of wastewater, it is generally discharged directly into the water body without treatment, resulting in eutrophication of the water body. For catering The main problems in sewage treatment are oil removal, reduction of CODCr and turbidity

Abstract

The invention provides a method for treating kitchen waste water. It includes the following steps: (1) Take the sludge from the anaerobic section and mix it with kitchen wastewater, put it into the anaerobic column, settle after stirring, and discharge the sludge at the bottom; Continuously feed water into the oxygen column, and react after the column is full of water, wherein the biofilm filler is prepared from the following ingredients: Step 1: Mix and dissolve shellac resin and absolute ethanol; Step 2: Add anion Ball milling of cellulose, sepiolite clay and peanut shell biochar; Step 3: Add the remaining ingredients, microwave treatment, ultrasonic oscillation; Step 4: After the absolute ethanol has evaporated, put it into a twin-screw extruder to extrude Get it by granulating; (3) Drain the treated water and measure its index. The purpose of the present invention is to provide a method for treating kitchen waste water, which can effectively remove the grease in the waste water, and has a good removal effect on COD and BOD in the waste water.

Description

technical field [0001] The invention relates to a method for treating kitchen waste water. Background technique [0002] With the rapid development of our country's economy, the catering industry and tourism industry have also developed. The related problems are the pollution of kitchen wastewater in hotels, hotels and other catering industries, and the amount of wastewater discharged is increasing. The pollution problem of catering wastewater is becoming more and more serious. Because the wastewater contains a high concentration of animal and vegetable oils and a large amount of suspended solids, it becomes an important source of water pollution. Catering wastewater has the characteristics of high BOD and COD concentration, high oil content, and large discharge. At the same time, because there are relatively few toxic substances in this type of wastewater, it is generally discharged directly into the water body without treatment, resulting in eutrophication of the water bo...
