Abstract

The invention relates to the technical field of sewage purification, and particularly relates to an urban sewage purification material which is prepared from the following raw materials in parts by weight: 15-30 parts of natural zeolite, 10-15 parts of a hydrochloric acid solution, 18-20 parts of a potassium aluminum sulfate solution, 20-25 parts of a sodium hydroxide solution, 16-18 parts of a ferric chloride solution, 20-30 parts of an acrylamide monomer, 26-28 parts of attapulgite powder, 12-16 parts of ferrous sulfate, 14-18 parts of sodium hydrogen sulfite and an appropriate amount of deionized water. In a modified zeolite filter material, the ion exchange adsorption capacity is increased, the service life is prolonged, the water purification effect is significantly improved, moreover, fluorine, arsenic, ammonia nitrogen, heavy metals and other pollutants in the water can be simultaneously removed; in addition, since a modified cationic flocculant is rich in high-density positivecharge, a stable treatment effect can be maintained when the water temperature is low; and moreover, the modified cationic flocculant is rich in micro-fiber pore adsorption material, which can adsorband remove multiple types of dirt in a water body.

Description

technical field [0001] The invention relates to the technical field of sewage purification, in particular to an urban sewage purification material. Background technique [0002] Urban sewage refers to domestic sewage, industrial wastewater and runoff sewage within urban areas. Generally, it is collected by urban pipes and canals and should be treated by urban sewage treatment plants before being discharged into water bodies. In addition to containing a large amount of organic matter, germs and viruses in urban sewage, due to the high development of industry, the water volume of industrial wastewater (accounting for about 60-80% of the total urban sewage), the water quality is becoming more and more complex and the pollution of runoff sewage is becoming more and more serious, making urban sewage Contains various types and degrees of various toxic and harmful pollutants. The treatment of urban sewage involves many aspects, and comprehensive planning must be carried out for t...
