Sludge harmless condensation greening bag and method

Abstract

The invention discloses a sludge harmless condensation greening bag and a method. The greening bag comprises a waterproof bag body, which is communicated with a sludge inlet pipe; a filtering box bodyis fixed on the inner wall of the waterproof bag body; a plurality of water holes are formed in the surface of the filter box body; a gravel filtering layer and an activated carbon filtering layer are fixed in the filtering box body; the activated carbon filtering layer is located on the inner side of the gravel filtering layer; the filtering box body is communicated with a water outlet; at leastone green plant transpiration area is paved on the upper surface of the waterproof bag body and comprises a covering film, a biological capsule and a degradable permeable layer at the bottom, a breathable covering film layer is arranged above the degradable permeable layer, and a water retention layer is arranged between the degradable permeable layer and the breathable covering film layer; the biological capsules penetrate through the breathable film covering layer and are inserted into the water retention layer. The greening bag is simple in structure and convenient to use, the problem thatthe surrounding environment is easily polluted in the sludge treatment process is solved, meanwhile, green plant treatment on the ground is achieved, and in addition, underground water pollution caused by sewage seepage in sludge is also prevented.

Description

[0001] Technical field: [0002] The invention belongs to the field of sludge treatment, in particular to a sludge harmless condensation greening bag and method. [0003] Background technique: [0004] A lot of silt is usually dug out in river course improvement and village and town environment cones. Dedicated drainage and filtration pipes and sites are usually required during sludge treatment. If the silt is dehydrated in the open air, it is easy to deteriorate and emit a foul smell, and it is easy to be used as an egg-laying ground by flies, causing flies to breed, and in the drying process, usually after the surface layer is dry, the bottom silt is still very wet, and the surface layer is initially dry. Silt is easy to generate dust and cause pollution to the surrounding environment. In addition, some silt contains pollutants such as heavy metals, and there are also some high-permeability soil areas, etc., which have the problem of polluting groundwater sources with sewag...

Problems solved by technology

[0006] The purpose of the present invention is to provide a sludge harmless condensation greening bag and method. The present invention is simple in structure, easy to use, and realizes the greening treatment of the ground while preventing the pollution of the surrounding environment during the sludge treatment process. In addition, it also prevents the groundwater pollution caused by the sewage seepage in the sludge, and also solves the explosion accident caused by the accumulation of biogas that may be caused by the pond storage and bag storage of sludge
