Abstract

The invention discloses a pathogen sewage treatment material which includes the raw materials including, by weight, 40-60 parts of a composite flocculant, 30-50 parts of a composite sterilizing agent, 10-20 parts of modified attapulgite, 10-15 parts of sodium carboxymethylcellulose, 2-6 parts of porous hydroxylapatite powder, 3-7 parts of poly-epichlorohydrin and 10-15 parts of polyamine polyether methylene phosphonic acid (PAPEMP). The composite flocculant includes cationic polyacrylamide, polysilicate ferric chloride and polyethyleneimine sodium xanthate according to the mass ratio of 1:2-3:1-2. The composite sterilizing agent includes sodium dichloroisocyanurate, polyhexamethylene biguanidine and water according to the mass ratio of 1:2-3:5-10. The invention also discloses a use method for the pathogen sewage treatment material. The pathogen sewage treatment material is easy to use and easy to promote, can treat sewages, such as domestic sewage, medicinal sewage, livestock and poultry breeding farm sewage, and wastewaters from leather production, scouring and slaughtering industry, etc., which contains pathogens and various pollutants, thereby protecting environment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment materials, in particular to a treatment material for pathogen sewage and a use method thereof. Background technique [0002] Although 70.8% of the earth is covered by water, fresh water resources are extremely limited. What we can really use are rivers, lakes and groundwater, which only account for 0.26% of the total water on the earth, and the distribution is uneven. After the 1950s, the global population grew rapidly and industries developed rapidly, accompanied by the rapid deterioration of the global water resources situation, and the "water crisis" became increasingly serious. On the one hand, the human demand for water resources is increasing at an alarming rate; on the other hand, the increasingly serious water pollution erodes a large amount of water resources available for consumption. [0003] The situation of water pollution continues to aggravate, which has attracted more and...
