Abstract

The invention relates to a refuse leachate treatment system. The refuse leachate treatment system comprises a waste water regulating pond, a coagulating sedimentation pond, a packing-type anoxia anaerobic reaction pond, an electrolytic pond, an aerobic contact oxidation pond and a sand filter pond; the coagulating sedimentation pond comprises a mixing stirring area and a sedimentation area, the bottom of the mixing stirring area is provided with a waste water inlet pipe, the middle-upper part of the mixing stirring area is provided with a liquid charging system for charging a coagulating agent, and the middle part of the stirring area is provided with a stirring apparatus; the packing-type anoxia anaerobic reaction pond comprises an anoxic section, an anoxia section and an anaerobic section; the electrolytic pond is provided with a water inlet pipe and a water outlet pipe, the electrolytic pond is of a structure of two chambers in the left-right direction, i.e. a positive electrode chamber and a negative electrode chamber; the middle-lower part in the aerobic contact oxidation pond is provided with a water inlet pipe, the lower part of the water inlet pipe is provided with a water distribution triangular cone, the lower part of the water distribution triangular cone is provided with an aeration control system, and the aeration control system comprises an aeration disc, an air blower and a dissolved oxygen measurement control apparatus.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a landfill leachate treatment system. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards, there are more and more garbage, which produces a large amount of landfill leachate. Landfill leachate is highly toxic and contains a variety of organic matter, high concentrations of ammonia nitrogen, inorganic salts, heavy metals and many other pollutants, and its water quality varies greatly. Improper treatment will pose a threat to surrounding soil, surface water, groundwater and human health. [0003] Biochemical treatment of landfill leachate has the advantages of good treatment effect and low cost. It is currently a widely used wastewater treatment method. However, for landfill leachate with low biodegradability and high toxicity, the effect of biochemical treatment is often not ideal. [0004] The co...
