Hazards of garbage leachate

Landfill leachate is a kind of highly polluted liquid produced in the process of landfill or incineration. It contains a variety of organic pollutants, heavy metals and biotoxic substances, which pose a serious threat to the environment and human health.

First of all, the garbage leachate has a strong odor, which seriously pollutes the atmospheric environment and affects the quality of life of the surrounding residents. Secondly, if the harmful substances in the leachate are discharged into the water body without treatment, it will seriously pollute the water source and destroy the water ecological balance. Moreover, when leachate enters the soil, it will change the composition and structure of the soil, affect the growth of crops, and even affect human health through the food chain. In addition, the toxic substances in leachate will destroy the physical and chemical properties of soil, reduce soil fertility and water content, and cause long-term effects on agricultural production and ecological environment.

In view of the serious harm of landfill leachate, it is particularly important to treat it efficiently and environmentally. MBR membrane technology is an effective means to treat landfill leachate at present.

Five advantages of MBR membrane treatment of landfill leachate

Efficient treatment effect: MBR membrane technology can degrade organic matter in leachate into harmless substances through microbial degradation, effectively remove harmful substances in leachate, and the treatment effect is far superior to traditional physical and chemical treatment methods.
High stability and reliability: the membrane separation technology in the MBR system can effectively prevent sludge loss and precipitation, maintain the stable operation of the system, and reduce the difficulty and cost of system maintenance.
Small footprint: Compared with traditional wastewater treatment processes, MBR technology uses membrane separation technology to make the reactor smaller in size and footprint, which is undoubtedly a major advantage for landfills with limited space in cities.
Low requirements for raw water quality: MBR technology can effectively separate solid particles and microorganisms in leachate through membrane separation, reducing the requirements for raw water quality and making the treatment process more flexible.
Environmentally friendly: MBR membrane technology does not produce secondary pollution in the treatment process, and has low energy consumption, which meets the requirements of green environmental protection, and is of great significance for protecting the ecological environment.
In summary, MBR membrane technology has significant advantages in the treatment of landfill leachate, and is an important technical means for the current and future landfill leachate treatment. With the continuous progress of technology and the promotion of applications, it is believed that MBR membrane technology will play a greater role in the field of environmental protection.
