Contaminated soil in-situ remediation equipment

Abstract

Provided is contaminated soil in-situ remediation equipment. The contaminated soil in-situ remediation equipment comprises a traveling rack. The traveling rack is sequentially provided with a rotatable soil loosening bar, rotatable soil breaking bars and a rotatable soil remediation bar. The soil loosening bar, the soil breaking bars and the soil remediation bar are connected with the top of the traveling rack through a first telescopic rod, second telescopic rods and a third telescopic rod. Soil scarifiers are evenly distributed on the outer wall of the soil loosening bar. The two soil breaking bars are distributed side by side and are opposite in rotation direction. A gap allowing soil to pass through is reserved between the soil breaking bars. The soil remediation bar and the third telescopic rod are both of a hollow structure and communicate with each other. Chemical spray holes are formed in the soil remediation bar. The top of the third telescopic rod communicates with a chemical tank arranged on the top of the traveling rack. The contaminated soil in-situ remediation equipment can carry out loosening, breaking and remediation of soil simultaneously, the remediation procedures of contaminated soil are simplified, the remediation efficiency of contaminated soil is greatly improved, and the remediation effect is good.

Description

technical field [0001] The invention belongs to the technical field of remediation of polluted soil, and in particular relates to a device for remediating polluted soil in situ. Background technique [0002] As the foundation of human survival, soil is an indispensable material wealth in our life. The utilization and protection of soil resources are closely related to the survival and development of human society. With the continuous acceleration of the industrialization process, the unreasonable exploitation of mineral resources and their smelting discharge, the long-term sewage irrigation and sludge application to the soil, the atmospheric subsidence caused by human activities, and the application of chemical fertilizers and pesticides have caused serious soil pollution. pollute. Soil pollution can directly pollute crops and reduce production, leading to direct economic losses. At the same time, harmful substances can accumulate in crops and enter the human body through t...
