Description

A kind of water floating head shape regulating reservoir

Technical field

This utility model relates to technical field of landfill leachate treatment, is specifically related to a kind of regulating reservoir for percolate.

Background technology

Along with the continuous quickening of urbanization process, China's municipal refuse annual production is also increasing year by year. At present urban domestic refuse sanitation burying landfill is processed and attaches great importance to by country, newly-built many large-scale landfills. But, the percolate produced in garbage loading embeading process is as a kind of important underground environmental pollution source, and its process problem is restriction garbage loading embeading technical development and the bottleneck problem controlling landfill yard ambient contamination. Landfill yard day processes increasing of quantity of refuse, result also in the increase year by year of percolate yield. The leachate equalization basin of landfill yard is the important polluter producing foul smell, and biogas produced by the percolate that regulating reservoir stores belongs to flammable explosive gas, so to biogas Ying You tissue collecting and guide. Substantial amounts of percolate enters regulating reservoir eventually through collection system, and the design of percolate from garbage filling field regulating reservoir is had higher requirement by this.

At present, leachate equalization basin mainly adopts armored concrete pool structure. Due to factors such as the heat of hydration, temperature, solar radiation, the deformation of concrete early-age shrinkage, humidity change and foundation deformations, easily there is crack in steel reinforced concrete pool pool wall, causes that regulating reservoir anti-permeability performance declines, and percolate leaks, and pollutes surrounding. Domestic at present also have employing geomembrane, but rain and can make geomembrane compressing deformation, even results in geomembrane deformation fracture, makes rainwater penetrate in regulating reservoir, strengthen the treating capacity of percolate. The design storage capacity of the leachate equalization basin of domestic landfill yard is generally large, and the surface of most regulating reservoirs is opened wide and arranged, foul smell is naturally excessive, and surrounding is caused serious pollution by this. Building lid according to steel construction, its cost is high, and sealing effectiveness is poor, and steel construction is easily subject to corrosion for a long time under sewage and foul smell environment.

Further, described discharge tube wall is evenly distributed with gas collection hole, for collection and the discharge of gas.

Further, described regulating reservoir includes percolate drainage device, and one end of described percolate drainage device is connected by pipeline with bottom of the reservior, soot, and the other end is connected with percolate treating stations by pipeline.

Further, described geomembrane is HDPE geomembrane, and described float tube is HDPE float tube.

Further, the periphery of described geomembrane and limit, regulating reservoir storehouse are by anchoring groove fixing seal.

Compared with prior art, a kind of water floating head shape regulating reservoir provides the benefit that: float tube is floated the water surface by rainwater by (1) water floating head shape covering system, thus rainwater and percolate being effectively isolated, it is prevented that rainwater mixes with percolate, reduce percolate treating capacity; (2) barrier properties of geomembrane is good, can effectively prevent leachate leaking; (3) regulating reservoir is discharged by gas gathering system foul smell is organized to be collected, and by the gas collected by spontaneous combustion or recycling, reduces the foul smell pollution to environment; (4) setting of percolate guide system, has effectively contained the leakage of percolate in whole garbage processing procedure.
