Embodiment 1

[0023] A sewage purifying agent 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 calycosin , 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 the modified bentonite is as follows: After mixing bentonite, sulfuric acid and modifier polybehenyltrimethylammonium chloride according to the mass ratio of 8:1:1, react at 50°C 1h; After the reaction, after washing to neutrality and filtering, the resulting filter cake was 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 high in adsorption capacity. high.

Abstract

The invention discloses a sewage purifying agent capable of efficiently removing total ammonia nitrogen, which is prepared from the following raw materials: modified bentonite, modified medical stone, modified clay, microbial strains, calycosin-7-O-glucopyranoside, calcium stearate, carboxymethyl cellulose, sodium lignin sulfonate, chitin and humic acid. The modified bentonite is added and has ultrahigh porosity and specific surface area, light weight and high adsorption capacity; the ion exchange capacity and adsorption capacity of medical stone are greatly improved by adding the modified medical stone, the modified medical stone can be used for adsorbing and removing ammonia nitrogen and heavy metal ions to achieve the effect of purifying a water body; themodified clayis added and has a large number of nano micropores by adding the modified clay, has very strong adsorbability, and can adsorb harmful substances or heavy metals such as algae pollutants, organic pollutants, chlorides, nitrites, cyanides, lead, mercury, arsenic and the like; and the carboxymethyl cellulose and the sodium lignin sulfonate are added and have a synergistic effect, so that the sewage treatment effect is improved.

Description

technical field [0001] The invention relates to the technical field of sewage purifiers, in particular to a sewage purifier for efficiently removing total ammonia nitrogen and a preparation process thereof. Background technique [0002] Sewage treatment: the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or for reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also 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 improved, the efficiency of sewage treatment is not high, and the treated water often cannot meet the discharge or use standards, and needs to be treated twice. deal with.
