Abstract

The invention relates to a wastewater treating agent, a preparation method and a wastewater treatment method. According to the oil paint wastewater treating agent, the formula comprising a corrosion inhibitor, a scale inhibitor, a sterilizing agent and a flocculating agent is adjusted, and an auxiliary chemical is added, so that the wastewater treatment process is easy to control, the treatment period is short, and the treatment effect is remarkably improved; the wastewater treating agent comprises the corrosion inhibitor, the scale inhibitor, the sterilizing agent, the flocculating agent and the auxiliary chemical; the corrosion inhibitor comprises sodium polyphosphate, calcium gluconate, alkyl epoxy sodium carboxylate, potassium iodide and gelatin; the scale inhibitor comprises trisodium phosphate, tannin, sodium humate, sulfoacid copolymers and TH-0100 type reverse osmosis scale inhibitors; the sterilizing agent comprises potassium permanganate, didodecyl dimethyl dibenzyltinoammonium chloride and nano-zinc oxide; the flocculating agent comprises lignin, chitosan, quaternary amine type cationic starch, polyaluminum chloride , polymeric ferric sulfate and diatomite earth; the auxiliary chemical comprises polyaspartic acid and alky epoxy carboxylate. An experiment result proves that the wastewater treating agent has an excellent effect.

Description

technical field [0001] The invention belongs to the field of wastewater treatment, and in particular relates to a wastewater treatment agent, a preparation method and a wastewater treatment method. Background technique [0002] With the development of society, the massive discharge of industrial sewage and urban wastewater has brought great challenges to the environment. Wastewater produced in different environments has great differences in ammonia nitrogen, COD content, PH value, and electrical conductivity, making it difficult to have wastewater treatment agents and water treatment methods suitable for multiple industries. Water treatment agents can be divided into two categories: one is chemicals with clear molecular structural formula and compound name, which are part of fine chemicals; The molecular structural formula and the name of the compound, and the product is named after its use, performance characteristics (often with a brand name). People often refer to the f...
