The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The ingredient of the percolate is complex, and the prior technologies of fermentation, reverse osmosis and the like on the market can not meet the requirement of treating the percolate.
Among these, the permeate has various characteristics, such as:
1. the leachate has complex components: the percolate contains fatty acids with low molecular weight, carbohydrates with high molecular weight such as humic substances and fulvic acid substances with medium molecular weight. Although the concentration of a particular contaminant in the leachate is low, the total amount of the contaminant is large due to its wide variety;
2. the organic pollutant and NH +42N content are high: it was identified that there are 93 organic compounds in landfill leachate, 22 of which are blacklisted as EPA environmental priority pollutants. The high-concentration NH +42N is one of the important water quality characteristics of the landfill leachate of the middle-aged and the elderly people, and is also an important reason causing the treatment difficulty to be larger;
3. high heavy metal content, high chroma and malodor: the leachate contains various heavy metal ions, and the leaching amount of the heavy metal ions is usually higher when industrial garbage and household garbage are buried in a mixed manner. The chromaticity of the percolate can reach 2000-4000 times, and the percolate is accompanied by extremely heavy putrefactive odor. (4) Unbalance of the proportion of nutrient elements of the microorganisms: the content of organic matters and ammonia nitrogen in the landfill leachate is too high, but the phosphorus content is generally lower. (5) The COD and the BOD concentration are high, the COD is as high as tens of thousands, and the BOD also reaches thousands, but along with the extension of the landfill time, the BOD/COD value is even lower than 0.1, which indicates that the biodegradability of the percolate in the stable period and the old is poor.
