Decolouring deodorizing sewage treatment agent

Abstract

The invention discloses a decolouring deodorizing sewage treatment agent. The decolouring deodorizing sewage treatment agent is prepared from, by mass, 1.5 to 2.5 parts of polyacrylamide, 1 to 2 parts of a coagulant aid, 3 to 8 parts of potassium peroxodisulfate, 3 to 5 parts of bentonite, 10 to 20 parts of starch, 5 to 10 parts of solvent lignin, 5 to 10 parts of a sodium phosphate-sodium dihydrogen phosphate buffer system, 10 to 15 parts of nekal, 8 to 10 parts of polyepoxysuccinic acid, and 2 to 3 parts of aluminium polychlorid. The decolouring deodorizing sewage treatment agent is used for solving technical problems of the prior art that conventional flocculating agents are poor in effects, and secondary pollution is caused by reagent ingredients; the decolouring deodorizing sewage treatment agent is wide in pollutant treatment range, excellent in effect, and wide in raw material resource, is friendly to the environment, and is non-toxic; the structural design of the coagulant aid is special, and obvious effects on the aspects of algae killing, decolouring, deodorizing, and organic matter degradation are achieved.

Description

technical field [0001] The invention relates to the technical field of chemical wastewater treatment, in particular to a sewage treatment agent capable of decolorizing and deodorizing. Background technique [0002] With the technological innovation and rapid development of the industry, more and more wastewater has the characteristics of refractory biodegradability and high COD. The fine chemical industry often produces high-concentration ammonia-nitrogen wastewater. The concentration of ammonia nitrogen and COD in the wastewater is high. COD will cause the deterioration of the water quality of natural water bodies, destroy the water body balance, and cause the death of almost all organisms except microorganisms, which is extremely harmful to the water environment. It is very difficult to deal with.
