Abstract

The invention provides a method for processing landfill leachate of incineration plants, relates to the technical field of landfill leachate processing, and solves the technical problem that the energy consumption and operation cost of a conventional landfill leachate processing system are high. The method comprises following steps: anaerobic reaction treatment: processing landfill leachate by anaerobic reactions, carrying out hydrolysis to produce acids and methane, and obtaining supernate of anaerobic reaction treatment; reverse osmosis treatment: and subjecting the supernate to a reverse osmosis treatment to obtain a reverse osmosis processing liquid, wherein the reverse osmosis treatment comprises two serially connected and graded reverse osmosis treatments. The provided method is usedto process landfill leachate of incineration plants.

Description

technical field [0001] The invention relates to the technical field of landfill leachate treatment, in particular to a method for treating landfill leachate in an incineration plant. Background technique [0002] The characteristics of the leachate water quality of domestic waste incineration plants include: ① There are many types of organic matter. Heterocyclic aromatic hydrocarbon compounds; ②The concentration of organic matter is high and the range of variation is large, and the COD (chemical oxygen demand) value is generally between 30-70g / L; ③The biodegradability is good, and the biodegradability ratio of the leachate of domestic waste incineration plants (BOD (biochemical oxygen demand) / COD) is generally around 0.5, and the C / N of the leachate is generally around 20, which is easy to carry out biochemical treatment; ④The ammonia nitrogen content is high, and the ammonia nitrogen value of the domestic waste leachate of the incineration plant is 1.2g / L or above, while ...
