Abstract

The invention discloses a processing device for slaughter wastewater. The device comprises a water distribution system (1), a filtering system (2) and a water collection system (3), wherein the filtering system comprises a supporting layer and multiple layers of active filler layers, the water distribution system (1) comprises a water distribution mother tube and a water distribution branch tube, the tube diameter is DN400-800, the multiple layers of active fillers are biological fillers, the height of the filler layers is 1500 mm-2500 mm and is specifically determined according to the water quality of inlet water, water quantity and the like, and the water collection system (3) comprises a water collection mother tube and a water collection branch tube.

Description

technical field [0001] The invention relates to a method and device for treating waste water, in particular to a method and device for treating waste water from slaughtering, which are mainly applicable to newly-built, rebuilt and expanded slaughter waste water treatment plants, and can also be used in industrial sewage treatment plants with similar working conditions. Background technique [0002] Slaughtering industry is one of the pillar industries for earning foreign exchange through export and ensuring supply in my country. Slaughtering wastewater comes from livestock, poultry, and fish slaughtering and processing, and is one of the largest sources of organic pollution in my country. According to the survey, the discharge of slaughtering wastewater accounts for about 6% of the national industrial wastewater discharge. With the development of the economy and the improvement of people's living standards, the meat food processing industry will have greater development. The ...
