As the end point of urban waste treatment, the operation of landfills is not only related to the final destination of solid waste, but also closely related to the surrounding ecological environment and the health of residents. Greenhouse gases such as methane produced by landfills, as well as pollutants such as heavy metals in leachate, may cause irreversible damage to the environment. Therefore, we need to build a multi-dimensional risk assessment and prevention and control system to ensure the sustainable operation of landfills.

In-Depth Analysis Of Landfill Environmental Pollution And Health Hazards

The environmental pollution generated by landfills is not a single dimension. As a potent greenhouse gas, the impact of methane emissions on global climate change cannot be ignored. In addition, landfills may also release harmful gases such as hydrogen sulfide and ammonia, causing direct pollution to the atmospheric environment.

Leachate is another major hidden danger of landfill environmental pollution. Leachate contains high concentrations of organic matter, heavy metals and other toxic substances. If not handled properly, it will cause serious pollution to the soil and groundwater, threatening the drinking water safety of surrounding residents.

Long-term exposure to the environment around the landfill may lead to a variety of health problems. Respiratory diseases, skin diseases, digestive system diseases, etc. may be related to pollutants produced by landfills. In addition, some studies have shown that long-term exposure near landfills may also increase the risk of diseases such as cancer.

Refinement Of Multi-Dimensional Risk Assessment And Prevention And Control

Intelligent network for gas leak monitoring:

1. Traditional point monitoring is difficult to cover the entire landfill, while modern methane detectors, combined with the characteristics of expanding the detection range (300 meters), can build a monitoring network covering the entire field.

2. The characteristics of fast response (10 milliseconds) can quickly capture the instantaneous changes of gas leaks, combined with Internet of Things technology, to achieve real-time data transmission and remote monitoring.

3. Through detailed reporting of concentration and GPS leak location identification, not only can the leak point be accurately located, but also the severity and potential impact of the leak can be evaluated through data analysis.

Refined Management of Leachate Treatment:

1. Traditional leachate treatment mainly relies on physical and chemical methods, and modern treatment technologies also include biological treatment, membrane treatment, etc.

2. By regularly monitoring the leachate, we can understand the changes in its composition, adjust the treatment process in time, and ensure the treatment effect.

3. Using big data analysis, we can predict the amount of leachate produced and the changes in its composition, and provide decision support for the operation and management of treatment facilities.

Three-dimensional system for soil and groundwater monitoring:

1. Traditional soil and groundwater monitoring mainly rely on manual sampling and laboratory analysis, and modern monitoring technologies also include online monitoring, remote sensing monitoring, etc.

2. By setting up multiple monitoring points around the landfill, a three-dimensional monitoring system can be built to fully understand the spread of pollutants.

3. Using the geographic information system (GIS), the monitoring data can be visualized, which makes it easier for decision makers to understand the pollution situation and formulate remediation plans.

Diversified Measures for Health Protection of Surrounding Residents:

1. Traditional health protection mainly relies on health education and medical services, and modern health protection also includes environmental monitoring, risk assessment, etc.

2. By establishing a resident health file, the health status of residents can be tracked, and health problems can be discovered and dealt with in a timely manner.

3. Using big data analysis, the potential impact of landfills on residents’ health can be evaluated, providing a scientific basis for the formulation of health protection measures.

In-Depth Application Of Methane Detector In Environmental Pollution And Health Protection

Build an Environmental Monitoring and Early Warning System:

Integrate methane detectors with other environmental monitoring equipment to build a comprehensive environmental monitoring and early warning system.

By analyzing the monitoring data in real time, abnormal environmental pollution can be discovered in time, early warning can be given, and the impact of pollution on the environment and residents’ health can be reduced.

Assist in Environmental Pollution Source Tracing Analysis:

The precise positioning function of the methane detector can quickly locate the gas leakage point and assist in environmental pollution source tracing analysis.

By analyzing the composition of the leaked gas, the source of pollution can be determined, providing a basis for the formulation of governance measures.

Participate in Environmental Risk Assessment:

Incorporating the monitoring data of the methane detector into the environmental risk assessment model can improve the accuracy of risk assessment.

By analyzing the results of risk assessment, a scientific environmental risk management plan can be formulated to reduce environmental pollution and health hazards.
