Abstract

The invention discloses a high-chromaticity / high-turbidity wastewater treatment material, comprising the following materials according to parts by weight: 40-60 parts of a composite coagulant, 30-50 parts of a composite flocculant, 3-7 parts of magnesium sulfate, 5-10 parts of carboxyl methyl cellulose, 2-6 parts of porous hydroxyapatite powder, 4-8 parts of expanded vermiculite powder, and 10-15 parts of polyamino polyether methylene phosphonate (PAPEMP); the composite coagulant is made from polysilicate ferric chloride, polyethyleneimine-sodium xanthogenate and polysulfate ferric chloride according to a weight ratio of 2-3:1:1-2; the composite flocculant is made from anionic polyacrylamide and polyepichlorohydrin according to a weight ratio of 1-3:1; the invention also discloses usage of the high-chromaticity / high-turbidity wastewater treatment material. The treatment material provided herein is useful in treating high-chromaticity / high-turbidity wastewater difficult to treat and has good settling effect, and emitted water meets the standard for emission.

Description

technical field [0001] The invention relates to the technical field of sewage treatment materials, in particular to a treatment material for high chroma / high turbidity sewage and a method for using the same. 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 increasing water pollution has attracted more and more a...
