The invention discloses a landfill leachate treatment process and special equipment thereof. A landfill leachate is subjected to membrane separation, deamination and oxidation treatment, the obtainedeffluent ammonia nitrogen and COD meet emission standards, and the obtained ammonium salt can be recycled, thereby solving the problem that the landfill leachate with low C/N and high ammonia nitrogenis difficult to treat. 本发明公开了种填埋场垃圾渗滤液处理工艺及其专用设备，将填埋场垃圾渗滤液进行膜分离、脱氨、氧化处理，得到的出水氨氮、COD均满足排放标准，同时得到的铵盐可回收利用，解决了低C/N、高氨氮垃圾渗滤液难处理的问题。
