Method for biodegradation of pesticide residual liquid by using edible fungus chaff

Abstract

A method for biodegradation of a pesticide residual liquid by using edible fungus chaff comprises the following steps: respectively naturally air-drying the edible fungus chaff, surface soil and straw, and then crushing or chopping; mixing the edible fungus chaff, the surface soil and the straw evenly to obtain a mixed matrix, and adding water to make the water content be 60% of the maximal water-holding capacity; curing the mixed matrix for 10 days at the room temperature; filling the cured mixed matrix into a pesticide degradation reactor; arranging the pesticide degradation reactor near a farmland; and evenly spraying a pesticide on the surface of the pesticide degradation reactor, and making the pesticide biodegraded by the edible fungus chaff in the pesticide degradation reactor. The method has the advantages that the method is simple in process, easy to operate, and high in pesticide degradation effect; the used raw materials of the mixed matrix are rich in sources and low in price; and the method not only reduces the effects of pesticide point source pollution on soil and surface water, but also effectively utilizes waste, protects the ecological environment, is obvious in economic and technical effects, and is applicable to vigorous popularization and application.

Description

technical field [0001] The invention belongs to the technical field of pesticide degradation, and in particular relates to a method for degrading pesticide residual liquid by using edible mushroom chaff. Background technique [0002] For a long time, due to the improper handling of pesticides in the process of application, a large amount of high-concentration pesticide stock solution has been released into the soil or water with the process of dilution, filling to spraying equipment, cleaning spraying equipment, and residual pesticide treatment. They are all concentrated in the fixed places of the farmland, so the high-concentration and repeated point source discharge of pesticides has caused serious pollution of surface water, groundwater and soil. [0003] Bio-bed technology is a new type of pesticide microbial degradation technology, which has the characteristics of low cost, high efficiency, and easy operation and management. It has been put into use in developed countr...
