Problems solved by technology

However, soil remediation using the in-situ remediation method is usually a short-term treatment project. Once the water quality returns to normal, the project can be completed, and the supporting equipment will be removed from the project site. Therefore, the equipment is required to be easily disassembled and the auxiliary equipment is small.

Abstract

The invention discloses a highly-integrated multifunctional in-situ soil repairing complete apparatus. The apparatus comprises a main reaction tank and an integration device room which are connected by a pipeline, the main reaction tank comprises a dosing and reacting chamber, a Fenton oxidation chamber, a neutralization reaction chamber, a coagulation reaction chamber, an inclined plate sedimentation chamber, a sludge tank and a clear water tank which are sequentially connected, and an active carbon filter connected with the inclined plate sedimentation chamber and the clear water tank is arranged between the inclined plate sedimentation chamber and the clear water tank; and a self-cleaning filter, a sulfuric acid dosing device, a hydrogen peroxide dosing device, a ferrous sulfate dosingdevice, an alkali dosing device, a PAM dosing device and a volute sludge dewatering machine are arranged in the integration device room. The invention also discloses a water treatment method of the apparatus. The characteristics of an in-situ soil repairing technology and a Fenton oxidation technology are combined, and soil repairers are assembled to form the complete apparatus for production, sothe occupied area of the apparatus is reduced, and the integrated apparatus has complete functions; and two pipelines are connected, and devices are connected by steel wire flexible tubes, so the apparatus is easy to transport, mount and dismount.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a complete set of highly integrated multifunctional in-situ repairing soil equipment and a water treatment method thereof. Background technique [0002] Soil and groundwater remediation has become a hot spot in environmental protection research at home and abroad. Contaminated soil and groundwater remediation can usually be carried out in two ways: ex-situ remediation and in-situ remediation. In situ remediation (ISCO) does not require excavation and transportation of soil, and is widely used because of its low processing cost, simple operation and less damage to the environment. However, soil remediation using the in-situ remediation method is usually a short-term treatment project. Once the water quality returns to normal, the project can be completed, and the supporting equipment will be removed from the project site. Therefore, the equipment is required to...
