Urban wastewater disinfection preparation and application thereof

Abstract

The invention discloses an urban wastewater composite disinfection preparation and an application thereof. The preparation is prepared from the following components in percentage by weight: 20-40 percent of composite quorum sensing inhibitor, 20-40 percent of sodium hypochlorite, 20-30 percent of surfactant, 10-20 percent of inorganic polymer coagulant, and 0-20 percent of composite solubilizer. The preparation is prepared by compounding the quorum sensing inhibitor serving as a main component with the sodium hypochlorite, the surfactant and the coagulant with disinfection, sterilization, coagulation and other functions, can be used in further treatment of urban wastewater, can be used for improving the effects of disinfection and sterilization, and is safer, more environment-friendly and more effective.

Description

technical field

[0001] The invention relates to the application field of water treatment, in particular to a disinfectant for urban tail water and its application. Background technique

[0002] With the continuous improvement of my country's urbanization and level, the urban population has grown rapidly, and residents' requirements for quality of life have also been continuously improved. The impact of urban sewage treatment plant effluent on water bodies has also attracted widespread attention to health and safety issues. Generally, after the secondary treatment of urban sewage, the water quality has been improved and the bacterial content has been greatly reduced, but the absolute number of bacteria is still high, and there is a possibility of pathogenic bacteria. These microorganisms and some difficult-to-remove trace inorganic or Wastewater can be safely discharged into water bodies or recycled after removing organic pollutants. In the "GB18918-2002 Pollutant Discharge ...
