Description

Technical Field

[0001] The utility model relates to the technical field of soil restoration, in particular to a soil odor removal system. Background Art

[0002] Soil pollution refers to the presence of harmful substances in the soil that exceed the level of adverse effects on human health, ecosystems or economic activities. These harmful substances can include chemical substances such as heavy metals, organic compounds, radioactive substances, microorganisms and other pollution sources. Soil pollution is usually caused by human activities, such as industrial emissions, the use of pesticides and fertilizers, improper waste disposal, etc. The impacts of soil pollution on the ecosystem include affecting plant growth, water resource pollution, food chain poisoning and biodiversity loss. In the process of soil remediation at sites contaminated by pesticides, chemicals, etc., the soil is often troubled by odor. According to the "Technical Guidelines for Soil Pollution Risk Assessment for Construction Land" (DB33 / T 892-2022), a comprehensive analysis of the risks of implementing remediation is required, that is, the possible risk level of implementing the remediation project is determined from the types of remediation pollutants, the degree of pollution, the depth of remediation, the distribution of surrounding sensitive points, etc. This means that many odor sites cannot directly implement soil excavation and subsequent remediation. Therefore, it is usually necessary to remove the odor from the site before subsequent remediation work can be carried out.

The recovery device comprises a second water pump 4, and the second water pump 4 can adopt a model such as 300QZ, which can dive to a depth of two to twenty-five meters, and can effectively extract the wastewater and waste gas in the extraction well 13. The second water pump 4 is arranged in the extraction well 13, and one end of a pumping pipe 41 is fixedly installed at the water outlet of the second water pump 4, and the other end of the pumping pipe 41 is fixedly connected to a separation pipe 42, and one end of the separation pipe 42 is fixedly connected to an exhaust gas treatment device 43, and the exhaust gas treatment device can adopt a model such as KJ1600, which is small in size and convenient for installation while effectively treating exhaust gas, and the other end is fixedly connected to a wastewater tank 44.

[0021] like Figure 2 , Figure 3 and Figure 4 The separation device 5 shown includes a handle 51 and a ball valve 53. A transmission column 52 is fixedly connected to the bottom of the handle 51. The ball valve 53 is arranged at the junction of the water pumping pipe 41 and the separation pipe 42. The transmission column 52 passes through the water pumping pipe 41 and is fixedly connected to the ball valve 53 with the separation pipe 42. A guide hole 54 is opened in the ball valve 53, and the guide hole 54 is L-shaped. A water valve 6 is arranged in the third water pipe 34. The water valve 6 can adopt models such as GU16. This model can adjust the size of the water flow passing through, which is convenient for adjusting the flow rate of the deodorant. A water level sensor 7 is fixedly installed on the outer wall surface of one end of the water pump 41 close to the second water pump 4. The water level sensor 7 can adopt models such as CYW11. This model can effectively detect the water level height, which is convenient for timely extraction of waste water in the extraction well 13. It should be noted that the injection well 12 and the extraction well 13 in this equipment need to be dug in advance by the user using appropriate tools, and the injection well 12 and the extraction well 13 are as follows.

When the waste water in the extraction well 13 is extracted, you can hold the handle 51 and rotate it. The rotation of the handle 51 drives the transmission column 52 to rotate, and then drives the ball valve 53 to rotate, thereby changing the direction of the guide hole 54. At this time, starting the second water pump 4 will extract the waste gas in the extraction well 13 into the suction pipe 41, and make the waste gas pass through the guide hole 54 to flow to the waste gas treatment equipment 43 for storage, which is convenient for centralized treatment.
