Embodiment 1

[0023] A sewage purifier for efficiently removing total ammonia nitrogen, comprising the following raw materials in parts by weight: 40 parts of modified bentonite, 30 parts of modified medical stone, 35 parts of modified clay, 4 parts of microbial strains, and 1 part of mullein isoflavones , 2 parts of calcium stearate, 3 parts of carboxymethyl cellulose, 1 part of sodium lignosulfonate, 2 parts of chitin, and 2 parts of humic acid.

[0024] Wherein, the preparation method of described modified bentonite is as follows: after bentonite, sulfuric acid and modifier poly-behenyltrimethyl ammonium chloride are mixed homogeneously at 8:1:1 according to mass ratio, react at 50° C. 1h; after the reaction, filter after washing to neutrality, and the obtained filter cake is dried and activated at 100 ° C to obtain modified bentonite. Compared with ordinary bentonite, it has ultra-high porosity and specific surface area and is light in weight and has a high adsorption capacity. high.

Abstract

The invention discloses a sewage purifying agent for efficiently removing total ammonia nitrogen, which comprises the following raw materials: modified bentonite, modified medical stone, modified clay, microbial strains, mullein, calcium stearate, carboxymethyl fiber By adding modified bentonite, it has ultra-high porosity and specific surface area, light weight and high adsorption capacity. By adding modified medical stone, it can greatly improve The ion exchange capacity and adsorption capacity of medical stone can be used to adsorb and remove ammonia nitrogen and heavy metal ions to achieve the effect of purifying water. By adding modified clay, it has a large number of nano-micropores, which has strong adsorption and can absorb algae pollution. By adding carboxymethyl cellulose and sodium lignosulfonate, the two synergistically improve the efficiency of sewage treatment. processing effect.

Description

technical field [0001] The invention relates to the technical field of sewage purifying agents, in particular to a sewage purifying agent for efficiently removing total ammonia nitrogen and a preparation process thereof. Background technique [0002] Sewage treatment: The process of purifying sewage in order to make it meet the water quality requirements for discharge into a body of water or for reuse. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering and other fields, and is increasingly entering the daily life of ordinary people. [0003] In sewage treatment, sewage purifiers are commonly used, but although most of the treated or purified water quality has been improved, the efficiency of sewage treatment is not high, and the treated water often fails to meet the discharge or use standards, requiring secondary treatment. deal with.
