Problems solved by technology

The physical treatment method is the simplest water treatment method, which recovers the insoluble suspended pollutants in the sewage through physical separation. The physical treatment method can only deal with some simple wastewater treatment, but the treatment is very incomplete and it is difficult to meet the discharge standard; The chemical treatment method is to use chemicals to treat pollutants, including neutralization, flocculation, redox, etc.; the biological treatment method is to dissolve pollutants in sewage through microbial metabolism, but this method requires large investment and high operating costs

Abstract

The invention discloses a sewage treating agent, which comprises the following components in parts by weight: 20-40 parts of sodium phosphate, 10-15 parts of Ethylene Diamine Tetra (Methylene Phosphonic Acid), 10-20 parts of sodium phosphate, 4-8 parts of sodium tripolyphosphate, 2-4 parts of silver nitrate, and 4-8 parts of sodium polyacrylate. The sewage treating agent is capable of effectively removing pollutants in water, low in cost, and capable of reaching the emission standards.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a sewage treatment agent. Background technique [0002] The existing industrial and urban wastewater treatment methods include physical treatment, chemical treatment and biological treatment. The physical treatment method is the simplest water treatment method, which recovers the insoluble suspended pollutants in the sewage through physical separation. The physical treatment method can only deal with some simple wastewater treatment, but the treatment is very incomplete and it is difficult to meet the discharge standard; The chemical treatment method is to use chemicals to treat pollutants, including neutralization, flocculation, redox, etc.; the biological treatment method is to dissolve pollutants in sewage through microbial metabolism, but this method requires large investment and high operating costs.
