Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0032] Such as figure 1 Shown, the present invention provides a kind of treatment method that is used for incinerator landfill leachate, comprises the following steps:

[0033] Anaerobic reaction treatment step: carry out anaerobic reaction treatment on the raw liquid of landfill leachate, the reaction of organic matter hydrolysis to produce acid and methane occurs, and anaerobic reaction treatment supernatant is obtained;

[0034] Reverse osmosis treatment st...

Abstract

The invention provides a treatment method for landfill leachate in an incineration plant. The treatment method comprises the steps that raw landfill leachate is subjected to anaerobic reaction treatment and reverse osmosis treatment. Preferably, the treatment method further comprises the steps of pretreatment, chemicals feeding for softening and flocculation precipitation treatment, and ion exchange treatment. A process and equipment which are high in energy consumption and operating cost are avoided, so that the operating cost is greatly lowered. The treatment method has a good operating, operation and maintenance environment, and is very important in the aspects of prolonging the service life of a system and ensuring stable operation of the system; and most operation can be automaticallycontrolled, engineering operation is stable, and the service life of a film assembly is long.

Description

technical field [0001] The invention relates to the technical field of landfill leachate treatment, in particular to a treatment method for 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. The leachate of domestic waste incineration plants is mostly fresh leachate in a short period of time, and has not undergone obvious biochemical effects (anaerobic fermentation, hydrolysis, acidification, etc.) in the reservoir area, so it contains a large amount of heterocyclic aromatic compounds; The range of variation is large, and the value of chemical oxygen demand (COD) is generally between 30-70g / L; ③Good biodegradability. The biodegradability ratio (BOD / COD ratio, BOD is biochemical oxygen demand) of the leachate of domestic waste incineration plants is generally around 0.5, and the carbon-nitrogen ratio (C / N) of the le...
