Problems solved by technology

However, due to its complicated preparation process, high cost and little impact on Escherichia coli and Enterococcus (Wang Cheng, et al. Chinese Journal of Agricultural Sciences, 2010, 26 (3): 23-26), to a certain extent, it restricts the production of Bacillus subtilis The antibacterial application of bacilli is also difficult to use on a large scale
The Chinese invention patent with the application number 200810030166.2 has announced a new type of compound quaternary ammonium salt disinfectant and its preparation method. Although it has the advantages of bactericidal spectrum, stable effect, non-toxic and non-irritating, it is easy to bring The problem of drug resistance in the process of antibacterial

Embodiment 1

[0052] according to figure 1 The formula and preparation process shown: First, weigh 20 kg of polyoxyethylene ether and 18 kg of anhydrous sodium bicarbonate, put them into a blender and stir evenly to prepare a composite solubilizer. Then weigh indole 30kg, 3,4-dibromo-2(5H)-furanone 30kg, AIP compounds (structural formula shown in formula (1), wherein R 1 and as R 2 Take the first type) 20kg, 20kg of 6-aminopenicillanic acid, and 20kg of coumarin and put them into a blender and stir evenly to prepare a compound quorum sensing inhibitor. Take 10kg of the above-mentioned composite solubilizer, 30kg of composite quorum sensing inhibitor, 25kg of sodium hypochlorite, 10kg of polyaluminum ferric chloride, and 25kg of dodecyl dimethyl benzyl ammonium chloride and put them into a blender to mix and stir evenly. After stirring for more than 30 minutes, use Sieve through a sieve with more than 200 meshes, filter out larger particles, press it into a sheet-like disinfectant, meet th...

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 ...
