由于垃圾渗滤液水质复杂，含有大量有机污染物，在垃圾渗滤液的处理过程中，为了保证出水效果，要注意以下问题：

1、水量和水质的季节性变化

垃圾渗滤液处理的水量和水质随季节而变化。一般来说，每年的雨季是5月到10月，旱季是11月到4月。雨季和旱季的水量几乎翻了一番，雨季的污染物浓度也远高于旱季。在运行过程中应制定不同的水量和水质变化响应计划。

2. Anaerobic system

If the anaerobic system of landfill leachate equipment adopts UASB process, the influence of large amount of water and water load should be avoided in the operation process to ensure the stability of UASB process system. At the same time, attention should be paid to the effluent phenomenon, timely monitoring of anaerobic effluent, timely treatment.

3. Supplement carbon sources

Since the discharge standard is "Domestic Waste Landfill Pollution Control Standard" (GB 16889-2008), the total nitrogen discharge standard is less than 40mg/L. Therefore, a secondary biochemical system was designed and operated in this project. According to the actual water intake and water quality, adjust the carbon source reflux ratio in time to ensure that the total water output of the system reaches the standard.

4. Membrane system is running

Landfill leachate membrane system mainly includes ultrafiltration system, nanofiltration system and reverse osmosis system. According to the inlet water quality, membrane operating pressure and other parameters timely maintenance, regular cleaning and maintenance. The system can run stably for a long time

5, safe operation
