Abstract

The invention discloses a deodorization and degradation treating agent for garbage leachate, which is used or carrying out treatment aiming at leachate of garbage from an urban garbage landfill and agarbage power plant, The deodorization and degradation treating agent is prepared from the following components in parts by weight: 7 to 10 parts of ammonium persulfate, 4 to 7 parts of sodium persulfate, 14 to 17 parts of sodium carbonate, 3 to 5 parts of sodium silicate, 8 to 10 parts of sodium cetyl sulfate, 4 to 6 parts of lauroyl aspartic acid, 3 to 5 parts of sodium oleyl sulfate, 6 to 9 parts of sodium stearyl sulfate, 5 to 8 parts of fatty alcohol polyoxyethylene ether, 3 to 5 parts of dilauryl tartrate, 9 to 12 parts of polyglycerol, 5 to 8 parts of potassium carboxylates, 3 to 6 parts of sodium n-alkyl sulfate and 7 to 10 parts of n-butyl polyacrylate. An aqueous solution, with a mass concentration of 0.5 to 0.8 percent, of the treating agent can be used for thoroughly dissolvingsulfur-containing and nitride-containing stinking water within several seconds in a normal-temperature condition to remove a peculiar smell, and can be used for decreasing BOD5 (Biochemical Oxygen Demand 5) in black garbage leachate with a foul smell to 50 percent or below within several minutes. The invention also relates to a preparation method of the deodorization and degradation treating agent for the garbage leachate.

Description

technical field [0001] The invention relates to a garbage leachate deodorization and degradation treatment agent for treating the leachate of garbage in urban garbage landfills and garbage power plants. The invention also relates to a preparation method of the landfill leachate deodorization and degradation treatment agent. Background technique [0002] In recent years, with the rapid development of my country's economy and the advancement of urbanization, the problem of urban waste disposal in my country has become increasingly prominent. The improvement of people's living standards has led to a sharp increase in the types and quantities of garbage. The problem of environmental pollution caused by landfill leachate has become increasingly prominent, and the quality of living environment has gradually declined, which has seriously affected people's living standards and physical health. [0003] Landfill leachate refers to the moisture contained in the garbage itself in the ...
