Treatment equipment for soil contamination

Abstract

The invention discloses treatment equipment for soil contamination. The treatment equipment comprises a base plate, a cylinder body, a water tank, a crushing cavity and a stirring cavity; the upper end of the base plate is fixedly connected to the crushing cavity through a supporting rod; the lower end of the right side of the crushing cavity communicates with the upper end of the left side of thestirring cavity through a through hole; the water tank is arranged at the upper end of the stirring cavity and communicates with the cylinder body arranged at the left end of the water tank through aguide pipe;a one-way valve is arranged in the guide pipe; a feed hopper is arranged at the upper end of the crushing cavity; a second motor is fixedly arranged at the lower end of the stirring cavity; the output end of the second motor is fixedly connected to a second rotating shaft; the lower end of the cylinder body communicates with spray pipes arranged at the upper end of the inner side of the stirring cavity through a guide pipe. The treatment equipment has the advantages that the design is novel, the operation is easy, soil is stirred when the soil is crushed and is added with an agentso that the agent can make full contact with the soil, the soil can be treated thoroughly, and therefore the defect that the soil is not comprehensively treated can be overcome, and the treatment effect can be improved.

Description

technical field [0001] The invention relates to soil treatment equipment, in particular to a treatment equipment for soil pollution. Background technique [0002] Due to the rapid growth of population and the rapid development of industry, solid wastes are continuously stacked and dumped on the soil surface, harmful waste water is continuously infiltrated into the soil, and harmful gases and floating dust in the atmosphere are also continuously falling into the soil with rainwater, resulting in soil pollution. Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium and fluorine, etc. Organic pollutants mainly include organic pesticides, phenols, cyanides, petroleum, synthetic detergents, 3,4-benzopyrene, and harmful microorganisms brought by urban sewage, sludg...

AI Technical Summary

Problems solved by technology

[0003] Most of the soil treatment is to spray liquid chemical reagents to the sudden surface to achieve the purpose of treatment. However, this method cannot uniformly treat all soils, the treatment effect is poor, and it will also lead to waste of liquid chemical reagents, and the cost investment is large.
