Leachate pool capping structure

Abstract

The invention discloses a percolate pool capping structure which comprises a floating cover film body and further comprises a concrete anchoring foundation, the floating cover film body is formed by welding a plurality of floating cover films, a plurality of floating ball strings are evenly distributed and connected to the bottom of the floating cover film body, and the edge of the floating cover film body is provided with an anchoring part exposed out of a percolate pool. The floating ball string anchoring part is flatly laid on the concrete anchoring foundation, a stainless steel plate is laid on the floating ball string anchoring part, the end, away from the percolate pool, of the floating ball string anchoring part is reversely rolled and laid on the stainless steel plate, and the floating ball string stainless steel plate and the anchoring parts located on the upper side and the lower side of the stainless steel plate are fixed in a penetrating mode through stainless steel expansion bolts. A concrete ballast layer covering the anchoring part, the stainless steel plate and the stainless steel expansion bolts is poured on the anchoring part located on the upper side of the floating ball string stainless steel plate, and a pedestrian path and a maintenance hole are formed in the upper surface of the floating ball string floating cover film body. The covering structure for the percolate pool is good in sealing effect, simple in structure and capable of preventing rainwater from entering the pool in rainy days.

Description

technical field [0001] The invention relates to the technical field of domestic waste treatment equipment, in particular to a capping structure for a leachate pool. Background technique [0002] At present, sanitary landfill is still the most important method of municipal solid waste disposal. As one of the structures set up in front of the leachate treatment system of the landfill, the leachate pool plays an important role in homogenization, regulation and storage or combined sewage pretreatment. If the pool is exposed and the covering system is not added in time, the odorous substances will diffuse into the atmosphere, bringing air pollution to the surrounding environment and seriously affecting the environment. At the same time, when it rains, a large amount of rainwater enters the pool, which will increase the amount of sewage produced. The traditional treatment methods are: biochemical method, light steel structure method and dry method. However, because the biodegra...

Problems solved by technology

Dry operation not only needs to empty the leachate tank, but also needs to clean up the sludge and other sediments in the tank, and it will also damage the anti-seepage system in the tank
