Soil pollution repairing condition regulating device

Abstract

The invention relates to a soil pollution repairing condition regulating device. The device comprises a peristaltic pump for providing power and controlling the flow, one end of the peristaltic pump soft pipe is inserted into a conditioning agent, the other end of the soft pipe is connected to a connecting pipe through an inside-outside thread connector, the connecting pipe is fixedly connected to a main pipeline, the main pipeline is communicated with a rotary three-way connector, the other end of the rotary three-way connector is communicated with a branched pipe, and the outlet end of the branched pipe is connected to an acid and alkali resistant rubber pipe containing a water permeable stone. The structure of the device is simple, the manufacture cost is low, the device is user-friendly, and the controllability is strong. The device is suitable for controlling multiple conditions during the process of soil pollution repairing, such as nutrition and water supply, inoculation of microecological preparation, oxygen increasing, pH adjustment, addition of chemical modifier, and the like. The environmental conditions of polluted soil can be continuously, evenly, and controllably adjusted by controlling the flow and flow speed of the peristaltic pump and the water absorption and control release effect of the water permeable stone.

Description

technical field [0001] The invention relates to an environmental condition control system, in particular to a soil pollution restoration condition control device. Background technique [0002] With the rapid development of modern industry and agriculture and the continuous improvement of people's living standards, a large amount of pollutants continue to enter the soil environment in various ways, which seriously affects the ecological function and use value of the soil, environmental quality decline, ecological degradation and other environmental problems Therefore, the remediation and control of soil environmental pollution is imminent. At present, the main remediation methods are chemical remediation and microbial remediation. The chemical remediation method is mainly to add some chemical reagents (chemical modifiers) to the soil to chemically react with the pollutants in the soil, so as to achieve the purpose of pollution removal or passivation. The microbial remediati...

Problems solved by technology

However, due to the physical characteristics of the soil, the injected substances cannot migrate, diffuse and dilute as easily as in the atmosphere and water bodies. Often, the concentration of the injected substances in a local area is too high, or the soil conditions change too quickly, causing adverse effects. Moreover, The adjustment of environmental conditions lacks continuity and controllability, resulting in very limited restoration effects
