Abstract

The invention discloses a sewage processing flocculating agent. The sewage processing flocculating agent comprises, by weight, 10 to 20 parts of diatomite, 8 to 15 parts of bentonite, 1 to 3 parts ofa microbial preparation, 3 to 8 parts of active carbon, 10 to 20 parts of bean leaf extracted product, and 10 to 15 parts of leaf extracted product. The sewage processing flocculating agent is short in flocculation time, and high in flocculation efficiency; combination of the bean leaf extracted product and the leaf extracted product is a key factor in increasing of the flocculation efficiency; after flocculation processing, no ingredient is left in water, no secondary pollution is caused. The sewage processing flocculating agent is suitable to be used for processing industrial wastewater anddomestic wastewater, and the suitable range is wide.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment flocculant. Background technique [0002] With the development of industrialization, more and more various industrial sewage and domestic sewage are discharged into the environment, polluting the environment and endangering human health. The methods currently used for sewage treatment include activated sludge method, permeable membrane method, and seepage method. and other methods. The biological removal of sewage by activated sludge is a widely used method. Activated sludge treatment of sewage requires the addition of flocculants to the sewage. The flocculation efficiency and quality of the flocculants are the key to the speed and quality of sewage treatment. [0003] Patent 200810022485.9 discloses a water treatment flocculant. Including metal cationic flocculants composed of one or more of aluminum sulfate, ferrous sulfate, zinc sulfa...
