Problems solved by technology

[0002] In the process of sewage treatment, a large amount of activated sludge will be produced. At present, physical separation methods are usually used to achieve the purpose of dehydration, such as centrifugal force method, gravity method and other methods. Separation of substances and mineralization by adding chemicals to liquid substances; this traditional method consumes a lot of energy and easily causes secondary pollution

Abstract

The present invention discloses a biological treatment mineralization ecological system for sludge. Said system includes artificial wetland bed which is a pool-shaped structure with four walls, on the four walls and bottom portion a water-proofing layer is respectively laid, on the water-proofing layer a filling material layer is set, said filling material layer includes coarse river sand and turf mixed layer, rice straw layer, large grain size broken stone layer and small grain size broken stone layer which are successively distributed from top to bottom. On the coarse river sand and turf mixed layer several slurry transmission pipes are horizontally laid, in the bottom portion of artificial wetland bed several water discharge pipes are horizontally laid, on the filling material layer the wetland plants can be planted, in its interior the microbe can be added.

Description

technical field [0001] The invention relates to a sludge biological treatment mineralization ecosystem. Background technique [0002] In the process of sewage treatment, a large amount of activated sludge will be produced. At present, physical separation methods are usually used to achieve the purpose of dehydration, such as centrifugal force method, gravity method and other methods. The material is separated and mineralized by adding chemicals to the liquid material; this traditional method consumes a lot of energy and easily causes secondary pollution. Contents of the invention [0003] In view of the above situation, the object of the present invention is to provide a sludge biological treatment mineralization ecological system that saves energy, does not need to add chemicals, is more natural, more ecologically harmonious, and environmentally safe. [0004] For achieving the above object, technical solution of the present invention is: [0005] A sludge biological tr...
