Embodiment Construction

[0074] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0075] This embodiment mainly has the following 10 processing units, which are summarized as follows:

[0076] 1. Grid / grit tank

[0077] After collecting the landfill leachate through the pipeline, it enters the coarse and fine grids and grit tanks to remove larger suspended matter, floating matter, fibrous matter and other larger solid particulate matter, and the separated matter enters the sand-water separator. Separate mud and sand.

[0078] 2. Regulating pool

[0079] The leachate flows into the regulating tank to be adjusted after sand settling. In this embodiment, the main functions of the conditioning tank are: ①, adjust the water volume and uniform water quality, reduce the impact load on the subsequent treatment system; ②, have a certain hydrolytic acidification effect. The adjustment tank transfers the excess leachate to the mud collecting well, and a ...

Abstract

The invention discloses a refuse incineration plant percolate treatment system, which comprises a coagulating sedimentation device, a biochemical device, a settling pond and a sludge concentration pond which are connected in series in turn, wherein the coagulating sedimentation device comprises a grid / grit chamber, a regulation pond and a reaction sedimentation pond, which are connected in turn in series; the biochemical device comprises an intermediate water pool, an upflow anaerobic sludge blanket (UASB) reactor, a secondary anacrobic / oxic (A / O) pond, a membrane bioreactor (MBR), a Fenton-electrochemical reactor and an aeration biological fluidized tank (ABFT), which are connected in series in turn; and the sludge in the reaction sedimentation pond, the UASB reactor, the MBR, the Fenton-electrochemical reactor and the settling pond is conveyed to the concentration pond. In the invention, the combined operation of the coagulating sedimentation pond, the UASB reactor, the secondary A / O pond, the MBR, the Fenton-electrochemical reactor and the ABFT is adopted, the ammonia nitrogen and organic matters in the percolate can be removed effectively, the amount of the concentrated liquidis reduced, the service life of the system is prolonged and the operation cost of the system is reduced.

Description

Technical field [0001] The invention relates to a garbage leachate treatment system, in particular to a garbage incineration plant leachate treatment system. Background technique [0002] The leachate is the sewage from the waste due to the decay, deterioration and fermentation of the organic matter of animals and plants. It usually has a foul smell and its main component is NH 3 -N, BOD, COD Cr , SS, Cl - And other filth. The leachate produced by the incineration process to treat garbage mainly refers to the water generated by the squeezing of the water contained in the garbage itself during the storage of the garbage and the water generated by the local anaerobic fermentation of the organic components in the garbage in the storage pit. A high-concentration organic wastewater with complex composition is formed. In addition, during the rainy season or after a long period of continuous heavy rain, garbage is washed by rain during transportation, and a large amount of rainwater is...
