      填埋场垃圾渗滤液处理设备的优点是什么?

      2021-02-03 11:53:59

        垃圾渗滤液是指来源于垃圾填埋场中垃圾本身含有的水分、进入填埋场的雨雪水及其他水分,扣除垃圾、覆土层的饱和持水量,并经历垃圾层和覆土层而形成的一种高浓度的有机废水。

        垃圾渗滤液组成复杂,水质和水量变化大,有机物和氨氮浓度高,微生物营养元素不平衡。填埋场垃圾渗滤液处理设备有效地解决了垃圾的处理问题,近年来得到了广泛的推广。让我们一起来看看吧:

      1. Reduced surplus sludge production


      The process of landfill leachate treatment equipment can be operated under large capacity load and low sludge load, and the surplus sludge yield is low (theoretically zero sludge discharge can be achieved), thus reducing the cost of sludge treatment.


      Landfill leachate treatment equipment occupies a small area and is not subject to installation restrictions


      The bioreactor can maintain a higher concentration of microbial biomass, and the treatment unit has a higher volume load, which greatly saves the floor space. Simple process, compact structure, save floor space, and is not limited by the installation site, suitable for any occasion, and can do ground, semi-underground and underground.


      2. The water quality of effluent is stable


      Because the membrane separation efficiency is high, the separation effect is much better than the traditional sedimentation tank. After treatment, the water quality is extremely clear, suspended solids and turbidity are close to zero, bacteria and viruses are greatly removed, and the water quality of effluent is better than the standard of living miscellany water quality promulgated by the Ministry of Construction. (CJ25.1-89) can be directly reused as non-potable water.


      At the same time, the membrane separation can also completely shut down the microorganism in the bioreactor, so that the higher microsystem in the system can be maintained.


      Biological concentration not only improves the overall removal efficiency of pollutants in the reactor, but also ensures good effluent quality. At the same time, the reactor has good adaptability to various changes of influent load (water quality, quantity), and can resist impact load. Stably obtain high quality effluent water quality.


      3, convenient operation and management, easy to achieve automatic control


      The process of landfill leachate treatment equipment realizes the complete separation of hydraulic residence time and sludge residence time, and the operation control is more flexible and stable. It is a kind of new technology which is easy to realize equipment and microcomputer automatic control in sewage treatment, so as to make operation and management more convenient.


      4, easy to convert from the traditional process


      Urban landfill leachate treatment equipment technology can be used as an advanced treatment unit of the traditional sewage treatment technology, and has a broad application prospect in the field of sewage treatment of urban secondary sewage treatment plants.


      5, can remove ammonia nitrogen and difficult to degrade organic matter


      Because microorganisms are completely shut down in the bioreactor, it is beneficial to the growth of slow-growing microorganisms such as nitrifying bacteria, which improves the nitrification efficiency of the system. At the same time, the hydraulic retention time of some refractory organic compounds in the system can be increased, which is beneficial to improve the degradation efficiency of refractory organic compounds.
