Abstract

The invention provides a water purification method, and belongs to the technical field of environmental protection. The method comprises the steps that physical purification is conducted first, then electrostatic bunching is conducted, and finally supernatant is filtered with particles made from silicon dioxide, activated carbon, calcium bicarbonate and ammonium bicarbonate. By means of the water purification method, the purification effect is good, impurity removal is thorough, water quality is further treated with microorganisms, the pH, chromaticity, COD, BOD5 and the content of sulfides, nitrides and organophosphorus are all decreased to be within specified standards, and therefore the purpose of water purification is achieved. It is shown through experiments that river water and lake water can be directly purified to be at the drinking water level by means of the purification method.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a water purification method. Background technique [0002] At present, the commonly used water purification methods are as follows: one is to purify with inorganic salts such as polyaluminium chloride, aluminum chloride hexahydrate, and aluminum sulfate; the other is to use high molecular polymers to purify; purify. Its cost is high, and the purification process is directly added to water for purification, and its purification effect is lacking. Contents of the invention [0003] In order to solve the above technical problems, the invention provides a method for water purification, the specific scheme is: [0004] A method for water purification, comprising the steps of: [0005] 1) Physical purification, adding 1 to 3% of its weight of physical water purifying agent to the water, and stirring for 30 to 60 minutes; [0006] 2) Electrostatic floc...
