Abstract

The invention provides a landfill leachate composite water treatment agent which comprises the following raw material component in parts by weight: 42-50 parts of polyacrylamide, 34-40 parts of polyaluminium sulfate, 34-40 parts of sodium polyacrylate, 25-30 parts of chitosan, 23-26 parts of potassium ferrate, 25-30 parts of expanded graphite, 25-30 parts of pyrophyllite, 25-30 parts of medical stone, 25-30 parts of coal ash, 33-36 parts of modified palm barks, 33-36 parts of active cocoanut charcoal and 18-22 parts of horseradish tree bark powder. The landfill leachate composite water treatment agent provided by the invention has multiple functions of flocculation, oxidation, adsorption, sterilization and the like, not only are harmful organic substances and heavy metal ions in living landfill leachate efficiently removed, but also microorganisms such as bacteria in the leachate can be effectively killed, and burden and influence upon later treatment processes can be alleviated.

Description

technical field [0001] The invention relates to the field of domestic garbage leachate treatment, in particular to a composite water treatment agent for domestic garbage leachate and a preparation method thereof. Background technique [0002] With the acceleration of industrialization and urbanization in our country, the total amount of urban waste is increasing year by year. At present, the treatment methods of municipal solid waste mainly include incineration and landfill, no matter which method is used to deal with waste, landfill leachate will be produced. Compared with urban domestic sewage and industrial wastewater, domestic waste leachate has more obvious characteristics. Its water quality components are quite complex, generally containing high concentrations of organic matter, heavy metal salts, SS and ammonia nitrogen, as well as many bacteria and microorganisms. In the early stage of pretreatment, if the high-concentration organic matter, heavy metal salts, microo...
