Abstract

The present invention discloses an efficient and economical waste water treatment coagulating agent, which comprises ferrous sulfate, aluminum sulfate, ferric chloride, polysilicic acid, zeolite powder, polysilicic aluminum ferric chloride, poly dimethyl diallyl ammonium chloride, an inorganic acid, an organic matter decoloring agent, a heavy metal capturing agent montmorillonite, and a COD absorption agent. The waste water treatment coagulating agent has the following beneficial effects that: heavy metals and organic compounds in waste water are removed through multiple effects, a decoloring effect is further provided, and an efficacy range is wide.

Description

technical field [0001] The invention belongs to the field of chemical industry, in particular to a method for preparing coagulant for wastewater treatment. Background technique [0002] With the development of industry, the pollution of the environment is becoming more and more serious. For example, there are more and more sewage containing heavy metal ions. The sewage containing heavy metal ions mainly comes from mechanical processing, mining, metal smelting, electronics industry and some chemical industries. industry. Acute or chronic poisoning can be caused when excessive heavy metals are ingested. Harmful to human health, waste water contains dozens of polycyclic and heterocyclic biodegradable substances such as phenol, benzene, pyridine, indole, quinoline, and harmful pollutants such as inorganic fluoride ions, ammonia nitrogen ions, and cyanide ions. The composition is complex , high pollution [0003] Traditional sewage treatment methods include chemical precipitat...
