Abstract

The invention relates to a purification and disinfection method for domestic water. The purification and disinfection method comprises the following steps: mixing chlorite and two acidic substances inproportion to obtain a purified water main material; heating and adhering a reverse osmosis membrane to the surface of a bag made of non-woven fabric to prepare a reverse osmosis membrane bag; preparing according to the size of a water body, and filling the purified water main material into the reverse osmosis membrane bag to prepare a chlorine dioxide slow-release bag; putting the chlorine dioxide slow-release bag into a pre-prepared balance container with the chlorine dioxide concentration of 1g / L; and pumping 1000ml of liquid from the balance container into one ton of domestic water, and maintaining the concentration of chlorine dioxide in the water body to reach 1mg / L. According to the purification and disinfection method for the domestic water, the chlorine dioxide slow-release bag is used for slowly releasing chlorine dioxide in the domestic water, the defects that a large water plant is high in investment requirement, high in site requirement and high in maintenance cost are overcome, and the purification and disinfection method can be conveniently popularized in villages, towns and remote areas to effectively solve the problem of the domestic water.

Description

technical field [0001] The invention belongs to the field of purification and disinfection, and relates to a purification and disinfection method for domestic water, in particular to a purification and disinfection method for urban and rural domestic water. Background technique [0002] At present, although my country has initially established a technical system for drinking water safety assurance, it still needs to be further improved. The statistical results of the National Bureau of Statistics show that with the increasingly serious environmental pollution, the treatment of domestic water in villages and towns has attracted more and more attention. At present, most rural households in our country live in scattered state, and they neglect the management of domestic water. Therefore, small domestic water purification devices suitable for single or joint households have gradually developed into the main technology of domestic water decentralized treatment in our country. ...
