Problems solved by technology

[0002] Domestic waste leachate is the secondary pollution produced after urban domestic waste sanitary landfill. It has the characteristics of various pollutants, large water volume, large fluctuations in water quality and no periodic changes. Under the action of the atmosphere, precipitation and garbage self-degradation , will directly or indirectly pollute water bodies, greatly affecting people's use of natural water bodies

Abstract

The invention relates to a pollutant retention performance test system and method of domestic waste leachate-based hydrogel. The test system includes a fan (1), an electric heating generator (3), an evaporator (7), and a condensation pipe ( 16), collection bottle (17), weight sensor (18) and display terminal (21), described blower fan (1), electric heating generator (3), evaporator (7), condensation pipe (16) and collection bottle (17) are connected in sequence, the collection bottle (17) is placed on the weight sensor (18), and the weight sensor (18) is electrically connected to the display terminal (21). Compared with the prior art, the present invention realizes the real-time measurement of the water release rate of domestic waste leachate-based hydrogel by evaporation, and realizes the quantitative research on its pollutant interception performance through the detection of water quality indicators.

Description

technical field [0001] The invention relates to the field of performance testing of pollutants, in particular to a pollutant retention performance testing system and method of domestic garbage leachate-based hydrogel. Background technique [0002] Domestic waste leachate is the secondary pollution produced after urban domestic waste sanitary landfill. It has the characteristics of various pollutants, large water volume, large fluctuations in water quality and no periodic changes. Under the action of the atmosphere, precipitation and garbage self-degradation , will directly or indirectly pollute water bodies, which greatly affects people's utilization of natural water bodies. In order to protect the natural environment and ensure people's normal production and life, effective treatment of landfill leachate is an urgent task. [0003] Based on the characteristic functional groups such as -COOH, -OH, and C=C contained in the leachate have the characteristics of free radical po...
