A precipitation infiltration measurement structure and its construction and measurement method

Abstract

The invention discloses a precipitation infiltration measurement structure and its construction and measurement method, and relates to the technical field of domestic waste treatment. The precipitation infiltration measurement structure includes a leachate guiding structure and at least one unit pile, and an anti-seepage layer is laid on the In the pit dug on the ground, its edge extends to the outside of the pit, domestic garbage is piled in the pit, above the anti-seepage layer, and a blind ditch is opened at the bottom of the pit below the anti-seepage layer , the blind ditch is filled with crushed stones to form the unit stack. The present invention is built near the landfill where facilities need to be built, and reproduces the climate, meteorology, geology, organic matter, garbage water content, rainfall and other conditions at the location of the landfill to the greatest extent, and accurately obtains different rainfall and different garbage treatment processes The actual output of landfill leachate under certain conditions can be used to guide the design and construction of landfill facilities with accurate data, improve the accuracy of design, and reasonably reduce the construction cost of facility construction.

Description

technical field [0001] The invention relates to the technical field of domestic waste treatment, in particular to a precipitation infiltration measurement structure, a construction method of the structure, and a method for measuring precipitation infiltration using the structure. Background technique [0002] Domestic waste is solid waste generated in daily life or activities that provide services for daily life. Simple landfill is a low cost, easy maintenance and operation method of domestic waste disposal. In the process of simple landfill of domestic waste, landfill leachate that is easy to cause secondary pollution to water body, soil and atmosphere will be produced. Therefore, it needs to be carried out strictly in a sanitary landfill. [0003] At present, the design and construction of treatment facilities in sanitary landfills are guided by the leachate production calculated by the seepage coefficient method, and the calculation formula of the seepage coefficient meth...

AI Technical Summary

Problems solved by technology

However, there is no specific collection and evaluation method for landfill leachate; at the same time, there is a 5-50% difference between the landfill leachate production predicted by the model and the actual production

Therefore, it cannot guide the actual landfill project very well

[0014] Through the above search, it is found that the above prior art does not affect the novelty of the present invention; and the mutual combination of the above prior art does not destroy the inventiveness of the present invention
