Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of water body substrate soil pollution remediation, and particularly relates to a deep treatment module of a water body substrate soil in-situ remediation device. BACKGROUND

[0002] Water body substrate soil refers to the soil deposited at the bottom of a water body, which is influenced by both the water body and the land, and is seriously polluted. Water body substrate soil pollution mainly includes heavy metal pollution, organic pollutant pollution, and acid pollution, etc. Common water body substrate soil pollution includes: 1) heavy metal pollution, which is the main type of water body substrate soil pollution. Heavy metals mainly come from human activities, such as industrial wastewater discharge, pesticide and fertilizer use, mining, etc. Heavy metal pollution can cause serious damage to the water ecosystem and enter the human body through the food chain, endangering human health. 2) organic pollutant pollution, which includes petroleum, pesticides, fertilizers, and organic industrial waste, etc. Organic pollutants can destroy the ecological balance of the water body and harm human health.

[0003] Water body substrate soil pollution can cause serious harm to the water ecosystem, crop production, and human health. 1) Water body substrate soil pollution can destroy the water ecosystem and cause fish and other aquatic organisms to die. 2) Water body substrate soil pollution can pollute crops, leading to excessive heavy metals and excessive organic pollutant content in agricultural products. 3) Water body substrate soil pollution can enter the human body through the food chain, causing heavy metal poisoning and cancer and other diseases in the human body.

[0004] At present, common methods for water body substrate soil pollution remediation include:

[0005] 1) Physical remediation technology:

[0006] Dredging: polluted sediment is excavated by mechanical equipment and treated or disposed of. It is suitable for areas with serious pollution, but the cost is high and can easily cause secondary pollution.

[0007] Covering: a layer of clean soil, sand or other materials is covered on the contaminated sediment to isolate pollutants. It is suitable for areas with low or stable pollution.

[0008] Solidification / stabilization: by adding solidification agents, pollutants are fixed in soil particles to reduce their migration and release. It is suitable for heavy metal contaminated soil.

[0009] 2) Chemical remediation technology:

[0010] Chemical oxidation-reduction: by adding oxidizing agents or reducing agents, toxic pollutants are converted into non-toxic or low-toxic substances. For example, hydrogen peroxide, ozone and other oxidizing agents are used to treat organic pollutants.

[0011] Chemical precipitation: By adding chemical reagents, dissolved pollutants are converted into insoluble precipitates, reducing their bioavailability. For example, by adding lime, phosphate, etc., heavy metals form insoluble compounds.

[0012] Adsorption: Using activated carbon, zeolite, and other adsorbent materials, pollutants are removed from water. Suitable for a variety of organic pollutants and some heavy metals.

[0013] 3) Bioremediation technology:

[0014] Biodegradation: Using microorganisms to degrade organic pollutants. By introducing specific microbial strains or activating the original microbial community, the degradation of organic pollutants can be accelerated.

[0015] Phytoremediation: Using aquatic plants to absorb and accumulate pollutants. Suitable for slightly polluted water bodies, by planting water hyacinth, reed and other plants, part of the heavy metals and organic pollutants can be removed.

[0016] Bioaugmentation: By adding nutrients or electron acceptors, the metabolic activity of microorganisms is enhanced, promoting the degradation of pollutants.

[0017] However, the use of the above repair technology alone usually requires large investment in manpower, materials and machines, and is easy to produce waste with high toxicity, causing secondary pollution.

[0018] In recent years, integrated remediation technology has been increasingly applied to water body foundation improvement projects. For example:

[0019] 1) Ecological restoration: Combining various biological, physical and chemical methods to restore the balance of water ecosystem. For example, through dredging, covering, phytoremediation and other comprehensive measures, not only pollutants are removed, but also ecological environment is improved.

[0020] 2) In-situ remediation: Without excavating the bottom mud, by adding remediation materials (such as activated carbon, microbial inoculum, etc.) and using devices for mixing and stirring, pollutants are degraded or fixed in-situ.

[0021] Although the current water body foundation soil treatment method has achieved certain results in pollution control, there are still problems such as high cost, secondary pollution, low efficiency and difficult monitoring.

[0022] In summary, the current conventional water body foundation soil treatment method has the following problems:

[0023] 1) High cost:

[0024] Dredging: The cost of mechanical dredging and disposal of contaminated bottom mud is very high, especially for large areas of contaminated areas.

[0025] Chemical remediation: The use of chemical agents is costly and requires precise control of dosage and reaction conditions.

[0026] 2) Secondary pollution:

[0027] Dredging: The dredging process can cause pollutants to resuspend in the water body, causing secondary pollution.

[0028] Chemical remediation: Improper use of chemical agents can lead to the generation of new pollutants or the accumulation of byproducts.

[0029] 3) Inefficiency and unstable effect:

[0030] Bioremediation: Affected by environmental conditions such as temperature, pH, and oxygen concentration, leading to unstable remediation efficiency and effect.

[0031] Phytoremediation: Plants absorb pollutants slowly, and the effect is limited in highly polluted areas.

[0032] 4) Difficulty in monitoring and control:

[0033] It is difficult to monitor and control the remediation process in real time, making it difficult to accurately assess the remediation effect and removal rate of pollutants.

[0034] 5) Limited scope of application:

[0035] Each method has its specific scope of application, and a single method cannot cope with complex and diverse pollution situations. SUMMARY
