Why does landfill leachate need to be fully quantified?

The quantitative treatment of landfill leachate is very important to protect the environment. This treatment significantly reduces the potential harm to ecosystems and human health by thoroughly breaking down pollutants such as organic matter and heavy metals. Fully quantified treatment not only avoids secondary pollution, but also ensures water security and supports the Sustainable Development Goals.

Project background

Huilai Hanwei Pit landfill has accumulated a large amount of landfill leachate due to long-term operation. The composition of leachate is complex, containing high concentration of organic matter, heavy metal and other pollutants, and it is very difficult to treat. The concentrated liquid separated by the traditional membrane system cannot be effectively disposed of due to high pollutants such as COD, ammonia nitrogen and salt content, so it is usually returned to the landfill site. As a result, the water quality of the leachate in the landfill site becomes worse, and the subsequent treatment is increasingly difficult. Therefore, we decided to use MVR full quantization technology to treat the leachate concentrate.

Treatment technology

The project adopts the full quantization process route of "pretreatment +MVR evaporation". First of all, the PH and the stability of water quality and quantity are adjusted through the pretreatment system to create favorable conditions for the subsequent evaporation treatment. Then, MVR evaporation system is used to vaporize and concentrate the pre-treated concentrated liquid, and most of the water and organic matter are removed. The condensed water produced by MVR can be returned to the original membrane treatment system for treatment and discharge after reaching the standard, and a very small part of the concentrated mother liquor is dried for landfill treatment.

Treatment effect

The leachate of the landfill has been effectively treated by MVR full quantization process. After treatment, the water quality is stable, the removal rate of organic matter is significantly increased, and the harmful substances such as heavy metals are effectively removed. At the same time, the process also realizes zero discharge of leachate and reduces the pollution to the environment.

Technical characteristics and advantages

MVR full quantization process has the following significant technical characteristics and advantages:
High efficiency evaporation concentration: The MVR evaporation system uses the steam generated by itself to heat evaporation, which greatly improves the evaporation efficiency and reduces energy consumption.

Environmental protection and energy saving: The process realizes the recycling of energy and reduces the treatment cost by recovering steam and utilizing waste heat.
Stable and reliable: MVR evaporation system adopts advanced control technology and intelligent management to ensure the stability and reliability of the processing process.
Wide application range: The process is suitable for the treatment of landfill leachate of different scale and different composition, and has a wide application prospect.

Conclusion and prospect

MVR full quantization process has shown remarkable effect and advantage in landfill leachate treatment. In the future, with the continuous improvement of environmental protection requirements and continuous progress of technology, MVR evaporation system will play a greater role in the field of landfill leachate treatment and make greater contributions to the cause of environmental protection.

Please note that each specific MVR fully quantified landfill leachate treatment case has its own unique characteristics and solutions, so in practical applications, the process design and optimization need to be tailored to the specific situation. At the same time, it is also necessary to pay attention to the treatment of secondary pollutants such as waste gas and waste residue that may be generated during the treatment process to ensure the environmental protection and sustainability of the entire treatment process.
