Abstract
The invention discloses a wastewater treating agent containing calcite powder. The treating agent comprises the following components in weight ratio: 18-26 parts of calcite powder, 13-16 parts of polylactic acid fiber, 12-15 parts of bamboo carbon fiber, 14-15 parts of poly-zinc silicate sulfate, 4-7 parts of silicon carbonate and 155-195 parts of water. The prepared wastewater treating agent can be used for remarkably reducing the contents of benzopyrene and ethylbenzene in industrial wastewater.
Description
Technical field
The present invention relates to a kind of waste water conditioner, particularly relate to a kind of waste water conditioner that contains calcite in powder.
Background technology
In the Chemicals manufacturing processed of chemical enterprise, can produce a certain amount of benzopyrene, these benzopyrenes are strong carcinogens, also have in addition ethylbenzene, the pollution of above-mentioned two kinds of materials is very serious.Therefore need to reduce the content of above-mentioned two kinds of materials in waste water.Reduce the benzopyrene content in black water, can adopt physisorphtion, method of chemical treatment etc.But the treatment effect of aforesaid method is not good, need to find a kind of method that can obviously reduce benzopyrene and ethylbenzene in waste water, remove benzopyrene and ethylbenzene in trade effluent.
Summary of the invention
The technical problem solved: the high problem of benzopyrene and ethyl-benzene level in trade effluent.
Technical scheme: the invention discloses a kind of waste water conditioner that contains calcite in powder, treatment agent is comprised of according to weight ratio following composition: calcite in powder is that 18～26 parts, acid fiber by polylactic are that 13～16 parts, bamboo-carbon fibre are that 12～15 parts, polysilicate sulfuric acid zinc are that 14～15 parts, carbonic acid silicon are 155～195 parts of 4～7 parts, water.
The preparation method is as follows: get each composition of environment-friendly type water treatment agent, calcite in powder is that 18～26kg, acid fiber by polylactic are that 13～16kg, bamboo-carbon fibre are that 12～15kg, polysilicate sulfuric acid zinc are that 14～15kg, carbonic acid silicon are 4～7kg, water 155～195kg.Above-mentioned each composition is poured into water, stirs 30 minutes, stirring obtains waste water conditioner after finishing.
Beneficial effect: the benzopyrene in trade effluent and ethylbenzene are after processing through treatment agent of the present invention, and benzopyrene content wherein is reduced to 1.3mg/L～1.7mg/L from 55mg/L, and ethyl-benzene level is reduced to 2.7mg/L～3.3mg/L from 72mg/L.
