Antipercolator for preventing soil pollution

Abstract

The invention provides an antipercolator for preventing soil pollution, which comprises an activated carbon fiber felt and a culture media which is arranged on the activated carbon fiber felt and contains microbial stains. Activated carbon fibers are large in specific surface area, fast in adsorption rate and desorption rate, high in adsorption efficiency and adsorption broad spectrum, good in adsorbing ability of various pollutants in soil and capable of avoiding soil pollution. Simultaneously, the activated carbon fiber felt can not block normal circulation of moisture in the soil, and therefore dead soil can not form. After the activated carbon fiber felt adsorbs the pollutants, the microbial strains in the culture media can decompose the absorbed pollutants in situ mode, and the pollutants can not be automatically released to cause secondary pollution. In addition, the activated carbon fiber felt can be regenerated in real time, thereby avoiding adsorbing saturation and influence on anti-seepage performance of the antipercolator, and further greatly prolonging service life of the antipercolator.

Description

technical field [0001] The invention belongs to the technical field of pollution prevention and control, and in particular relates to an anti-seepage device used for preventing soil pollution. Background technique [0002] With the development of industrialization, soil pollution is becoming more and more serious. Compared with air and water, the self-purification ability of soil is relatively low. Once it is polluted, it is difficult to repair. Moreover, after soil is polluted, it will directly affect the local vegetation, crops, groundwater and other ecological factors that are directly related to human survival. For example, after oil leaks into the soil, the oil pollutants will block the soil pores, reduce the air permeability and water permeability of the soil, change the carbon-nitrogen ratio and carbon-phosphorus ratio of soil organic matter, cause changes in soil biological communities and flora, and damage the soil micro-ecological environment; at the same time, pe...

However, this type of leak-proof membrane is generally a waterproof membrane. While blocking pollutants, it also blocks the normal circulation of water in the soil, making the soil in this area dead and destroying its normal ecological environment.
