Embodiment 1

[0025] A sewage treatment agent, in parts by weight, consists of the following components:

[0026]

[0027]

[0028] In the formula (1-1), a is 70 mol%, b is 8 mol%, c is 8 mol%, and d is 14 mol%, and the number average molecular weight of the copolymer is about 2 million.

[0029] The modified nano sepiolite powder is prepared according to the following method: after the sepiolite is pulverized, add 2mol / L hydrochloric acid aqueous solution for soaking treatment, the soaking time is 24h, the soaking temperature is 45°C, and the solid-liquid ratio is preferably 1: 15 (g : ml); suction filtration, the gained filter cake is washed to neutrality with deionized water, and dried to obtain acid-modified sepiolite powder; the quaternized dimethylaminoethyl acrylate (DMAEA) monomer is formulated into 15mmol / For the aqueous solution of L, add the acid-modified sepiolite powder in an amount of 1:15 (g:ml) according to the solid-liquid ratio, and after magnetic stirring at room t...

Abstract

The invention provides a high-efficiency sewage treating agent, comprising modified nanometer meerschaum powder, polyferric silicate sulfate, diethylenetriamine pentaacetate, polyferric chloride, sodium lignosulfonate, modified chitosan, resorcinol-thiourea-formaldehyde polycondensate, modified coconut shell-based active carbon and a copolymer as shown in a formula (I) which is defined in the specification. Through synergism of the above components of the sewage treating agent, the sewage treating agent has excellent comprehensive sewage treating capacity.

Description

technical field [0001] The invention relates to the field of urban sewage purification and treatment, in particular to an efficient sewage treatment agent and a preparation method thereof. Background technique [0002] According to the statistical analysis of environmental monitoring results, although my country has increased investment in environmental protection and strengthened comprehensive environmental management, the situation of water pollution in my country is still very severe, with a large amount of pollutant discharge and a relatively high level of pollution. Urban sewage discharge is already the main source of pollution in Chinese cities. With the acceleration of urbanization, the increase of water consumption and the increase of drainage, the demand for sewage treatment also increases, and the sewage treatment and regeneration industry has received unprecedented attention. [0003] At present, the most harmful to water bodies is man-made pollution, which is ma...
