Abstract

The invention provides a multifunctional water treatment agent for landfill leachate. The multifunctional water treatment agent for the landfill leachate comprises the following raw material components in parts by weight: 43-46 parts of polyacrylamide, 18-22 parts of pyrophyllite, 18-22 parts of medical stone, 18-22 parts of expanded graphite, 33-36 parts of modified palm bark, 25-30 parts of modified luffa fibers, 22-26 parts of cocoanut active charcoal, 10-12 parts of moringa oleifera bark powder, 13-16 parts of tourmaline powder and 8-11 parts of potassium ferrate. The multifunctional watertreatment agent for the landfill leachate has multiple functions of flocculation, oxidation, adsorption, sterilizing and the like, harmful organic matters and heavy metal ions in domestic garbage leachate can be removed effectively, furthermore, microorganisms such as bacteria in the leachate can be killed effectively, and thus, load and influences to a follow-up treatment process are relieved.

Description

technical field [0001] The invention relates to the field of landfill leachate treatment, in particular to a multifunctional water treatment agent for landfill 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, microorganisms, ...
