Embodiment Construction

[0017] Unless otherwise specified in the present invention, the pool body adopts reinforced concrete structure.

[0018] The leachate from the garbage bin first enters the coarse filter to remove larger magazines and large particle suspended matter, and then enters the primary sedimentation tank to further remove the suspended matter. The effluent from the primary sedimentation tank enters the comprehensive adjustment tank after passing through the struvite pool deal with. The coarse filter is made of stainless steel mesh. The design size of the primary sedimentation tank: 4.5m×4.0m×6.0m, equipped with 2 sets of sludge pumps, the feed liquid overflows into the struvite tank; the design size of the struvite tank: 7.1m×4.0 m×5.8m, there is an aeration pipe leading to the bottom of the pool for aeration, and then overflows into the comprehensive adjustment tank; the design size of the comprehensive adjustment tank: 12.6m×11.9m×4.8m, equipped with one-to-two hydraulic mixers for a...

Abstract

The invention discloses a method of effectively treating landfill leachate, which is capable of effectively treating the landfill leachate by adopting a method of post-treatment, anaerobic reaction, high-intensity aerobic reaction, anaerobic ammonia oxidation reaction, multistage multi-circulation anaerobic (aerobic) reaction and aerobic reaction, and producing methane simultaneously. When the leachate is effectively treated, the recycling methane is generated, the system has stable operation and good COD (Chemical Oxygen Demand) and ammonia nitrogen removal effect, and the treatment effect is better under the condition of complicated water quality and water yield fluctuation of raw material fluid. The method is a treatment method with better application prospect.

Description

technical field [0001] The invention relates to a method for treating landfill leachate, which belongs to the technical field of sewage treatment. Background technique [0002] The conventional disposal method of domestic waste in our country is sanitary landfill, but in recent years, due to the increasing amount of domestic waste, many cities in our country have fallen into the dilemma of "garbage surrounds the city". In recent years, more and more waste-to-energy plants have been in operation or are under construction. Although the problem of domestic waste treatment and disposal has been solved, the treatment of the landfill leachate generated immediately has become an urgent problem to be solved. Landfill leachate is the water produced by the decomposition of organic substances in the garbage, the free water in the garbage and the sewage formed by leaching during the transfer and treatment of domestic garbage, which contains a large amount of organic pollutants, nitroge...
