Abstract

A production method of a silicon- and aluminum-containing humate flocculating water purifier. According to parts by weight, add 100 parts of humic acid on a dry basis into a kneader, add 50 parts of water and knead and stir evenly, and continue kneading and stirring While adding 10-15 parts of sodium silicate, 5-10 parts of sodium aluminate, 5-10 parts of potassium hydroxide, continue kneading and stirring for 30 minutes, then add 5 parts of sodium metabisulfite, 5 parts of sodium bisulfite, continue Knead and stir for 30 minutes, add to a screw extruder, adjust the temperature to 150-180°C to form irregular strips, cool naturally, and pulverize to obtain a silicon and aluminum humate flocculating water purifier. The advantages are: good water purification effect, can remove mineral salts, metal salts, nitrite in water and soil, friendly to the environment, no secondary pollution; used to purify sewage without heavy metal pollution such as breweries and food processing plants When used, the purified sludge can be used to produce organic fertilizers and flower support substrates, realizing the reuse of waste.

Description

technical field [0001] The invention relates to a production method of a flocculating water purifying agent containing silicon and aluminum humate. It is mainly used for harmless water purification treatment of breweries, food processing plants, agricultural production and urban domestic sewage, and the sludge can be reused. Background technique [0002] Commonly used flocculating water purifiers are polymer polyacrylamides produced from dimethylamine, polyethylene polyamine, formaldehyde and acrylonitrile as raw materials, and polymerized with an initiator. In the process of water purification, aluminates, silicates, and hydrogen peroxide should be used together, and the effect is obvious. The sludge after water purification contains many non-degradable toxic and harmful amides, which cause secondary damage to the environment and cannot be reused. With the enhancement of people's awareness of drinking water and food safety, the impact of dissolved pollutants in water and ...
