Problems solved by technology

[0012] At present, there are no good engineering examples for the treatment of kitchen filtrate with this concentration. If it is discharged into the water body, it will make the water body too fertile, cause the trophic phenomenon of the water body, cause extremely serious harm to the aquatic organisms in the water area, and destroy human beings. Water resources for survival

Abstract

The invention discloses kitchen waste filtrate treatment equipment and method. The treatment method comprises the steps that the kitchen filtrate firstly enters an oil separation tank used for separating oil substances from water substances; the water after separation is converged into a regulating tank and the water quality and quantity are regulated; the effluent enters a reaction tank, PAC (polyaluminium chloride) and PAM (polyacrylamide) are added to the effluent, so that fine particles in the water form a plenty of alum flocs, and then the alum flocs precipitate to be separated in a precipitation tank, thus removing most oil and scum; the effluent from the precipitation tank automatically flows into a neutralization tank, the pH value is regulated to neutral and then the effluent enters a pressure dissolved air floatation tank used for removing the scum formed by the flocculated suspended matter particles or oil particles brought on the water surface from the wastewater; then the pollutants such as organic matters, ammonia nitrogen and the like are removed by the pretreatment+anaerobic+aerobic precipitation+sand filtration technology of an exclusively added backflow sludge contact reactor; finally the wastewater reaches discharge standard.

Description

technical field [0001] The invention belongs to the field of waste water treatment, and in particular relates to a treatment device and method for kitchen waste filtrate. Background technique [0002] The food waste filtrate comes from the production processes such as screening and extrusion of the food waste treatment station. The sources of food waste mainly include food waste generated in canteens such as hotels, office buildings, communities, and schools. [0003] Kitchen filtrate wastewater has the characteristics of high COD, high oil content, high salinity, high chroma, and large slag content. It belongs to the difficult wastewater treatment. [0004] Wastewater raw water contains a lot of oil and suspended solids. If all these substances enter the follow-up units such as biochemical reactions, the sludge will float up, and even the microorganisms will die. As a result, the quality of the effluent water will be unqualified. The separation of vegetable oil and some ...
