Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of separation and purification of pollutants and water in the waste water seeping out of domestic garbage dumps by means of a combination of chemistry and physics, so that the purified water can be discharged up to standard or reused for irrigating farmland, forests, etc.
The medicament used is the separated waste residue which will not cause secondary pollution to the environment

Abstract

The invention discloses a method for preparing and using a medicament for purifying and treating percolate waste water from a household garbage field, which relates to the field of waste water and air environment quality purification in the environment protection industry. In the invention, various chemical medicaments are prepared and diluted into liquid according to a certain proportion, and the liquid is dissolved in the garbage percolate waste water in three or four stages in different time, thus harmful impurities in the wastewater, such as COD, NH3-N, SS, heavy metal, colon bacillus, and the like are damaged and eliminated and completely separated from water and deposited, thus the water is clear and transparent, the household garbage burying pollution control standard GB16889-1997 and the integrated wastewater discharge standard GB8978-1996 can be reached or the water is reused for irrigating farmlands, forests, and the like. The wastewater can be continuously purified two or three times, and the reagent and the method can not cause secondary pollution to a water body.

Description

technical field [0001] The invention relates to the field of purification and slag removal of leachate wastewater from domestic garbage sites in the environmental protection industry. Background technique [0002] The composition of the liquid wastewater permeated from domestic garbage dumps is very complex, usually containing odor and high concentrations of soluble organic matter and inorganic ions, including a large amount of ammonia nitrogen and various dissolved cations, heavy metals, phenols, tannins, soluble fatty acids, coli and other organic pollutants. COD content in wastewater 3500mg / L, NH 3 -N400mg / L-560mg / L, COD-100mg / L higher than the standard required by the national environmental protection department, NH 3 -Dozens of times that of N15 mg / L, the traditional anaerobic, gas explosion, or biological treatment methods have been unable to completely solve the removal of high-level pollutants and odor in wastewater. It has been unable to adapt to solve the harm p...
