Organic fertilizer making process for reducing heavy metal pollution of soil

Abstract

The invention discloses an organic fertilizer making process for reducing heavy metal pollution of soil. The process adopts a bottom plate, wherein a support column is fixedly arranged at the upper end of the bottom plate; a storage bucket is arranged at the upper end of the support column; a conveying cavity is formed in the storage bucket; and a crushing device capable of cutting straw is connected inside the conveying cavity in a sliding manner. The organic fertilizer making process smartly utilizes the principle that a gravity center is kept perpendicular to the ground, a baffle door and a pendulum bob valve structure which are opened and closed through gravity are designed, unrelated impurities can be prevented from being mixed inside in the machining process, and in addition, through a blue alga storage tank of a constant volume and an automatic straw feeding mechanism, an appropriate mixing ratio of glue algae and straw can be ensured; and in addition, before mixing, the straw is cut and crushed, so that the mixing efficiency can be improved, the straw and the blue algae can be uniformly mixed and distributed, and the capability of treating heavy metals in soil can be ensured.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to an organic fertilizer production process for reducing soil heavy metal pollution. Background technique [0002] The chemical pollutants in the soil not only pollute the environment, but also affect the fertility of the soil, which may threaten the lives of the eaters. Therefore, making organic fertilizers that can reduce heavy metals is an important task facing modern science and technology. The combination of straw waste and blue-green algae, and adding a small amount of biomass conversion compound bacterial agent, can form a kind that can limit the mobility of heavy metals in the soil and reduce their bioutilization activity, reduce the toxicity of heavy metal pollutants to environmental organisms, and achieve Organic fertilizer for the purpose of repairing heavy metal polluted soil. [0003] The production method of this organic fertilizer requires step-by-step work,...

Problems solved by technology

[0003] The production method of this organic fertilizer requires step-by-step work, and the addition of straw and blue-green algae requires manual deployment of a suitable ratio. There are certain human subjective judgment factors in this process, which will affect the ability of the organic fertilizer to deal with heavy metals and cause secondary pollution. A kind of device that the present invention illustrates can solve the above problems
