Safe and environment-friendly sewage disinfection powder

Abstract

The invention discloses safe and environment-friendly sewage disinfection powder, which comprises, by weight, 30-50% of potassium monopersulfate, 3-10% of sodium chloride, 6-22% of sulfamic acid, 11-13% of a surfactant, 8-16% of a pH buffer agent, 10-41% of a stabilizing agent, 0-5% of an anticaking agent and 1-6% of a coating agent. Through the above mode, the product of the invention can be used for disinfection and sterilization of hospital wastewater, sewage from domestic sewage plants and industrial circulating water, and is non-combustible and in-explosive so as to eliminate the risk of chlorine leakage and explosion. According to the invention, safety, economy, environmental protection and high efficiency are integrated.

Description

Technical field [0001] The invention relates to the field of sewage disinfection powder, in particular to a safe and environmentally friendly disinfection powder for domestic sewage and hospital sewage. Background technique [0002] Urban domestic sewage refers to the waste water introduced into the sewage discharge pipe and defecation pipe, which includes domestic water, bathing water, and fecal flushing water. With the acceleration of economic development and the acceleration of urbanization and the improvement of living standards, the amount of sewage discharge is also increasing, and the environmental pollution is becoming more and more serious. Generally, domestic sewage contains 100,000 to 1 million bacilli / ml, in addition to various pathogenic bacteria, intestinal bacteria and worm eggs. [0003] Hospital sewage refers to the sewage discharged from the hospital to the natural environment or urban pipelines. The main pollutants contained in hospital sewage are: pathogens (p...

Problems solved by technology

The chlorination method has the advantages of convenient dosing, low price, and high reliability, but at the same time, monochloramine, dichloramine and trichloramine can be formed, and carcinogenic chloroform (THM) can also be formed, as well as in terms of safety. hidden dangers, prone to explosion, personal injury and other accidents

The ozone method is used for sewage disinfection, which can effectively kill coliform bacteria, and is not affected by the ammonia nitrogen content and pH value in sewage, but has the disadvantages of inability to sustain sterilization and high cost

Ultraviolet disinfection is more environmentally friendly and has strong sterilization ability, but it has no continuous sterilization ability, is affected by suspended solids and turbidity, and has high cost and expensive equipment
