Description
技术领域technical field
本实用新型涉及一种垃圾渗滤液膜浓缩液深度处理成套装置，属于渗滤液处理技术领域。The utility model relates to a complete set of device for advanced treatment of landfill leachate membrane concentrate, which belongs to the technical field of leachate treatment.
背景技术Background technique
城市垃圾填埋和焚烧技术中渗滤液的污染控制是的一大技术难题，目前渗滤液的处理大多采用“预处理+MBR膜生物系统+纳滤/反渗透深度处理”的组合工艺，出水基本能够达到我国2008年最新修订的《垃圾填埋场污染物控制标准》GB16889-2008的排放标准，由于垃圾渗滤液的处理中NF、RO膜的广泛使用，则必然产生一定量的膜浓缩液，约是进水规模的20％左右。浓缩液含有大量难降解的有机物、以及氨氮、总氮、高价盐分等，如果直接排入水体会致使水体污染，而且会对水体中动植物造成巨大的毒害作用，最终威胁到人类生命健康，还会带来巨大的经济损失。The pollution control of leachate in urban waste landfill and incineration technology is a major technical problem. At present, most leachate treatment adopts the combined process of "pretreatment + MBR membrane biological system + nanofiltration/reverse osmosis advanced treatment", and the effluent is basically It can meet the discharge standard of GB16889-2008 of the latest revision of the "Landfill Pollutant Control Standard" in 2008. Due to the wide use of NF and RO membranes in the treatment of landfill leachate, a certain amount of membrane concentrate will inevitably be produced. It is about 20% of the water intake scale. The concentrate contains a large amount of refractory organic matter, as well as ammonia nitrogen, total nitrogen, high-priced salt, etc. If it is directly discharged into the water, it will cause water pollution, and it will cause great toxicity to animals and plants in the water, eventually threatening human life and health. would cause huge economic losses.
目前，国内外处理垃圾渗滤液纳滤浓缩液的主要方法有：回喷焚烧、回灌、高级氧化和蒸发法等。回喷焚烧存在很多弊端，不仅损失燃烧热值，还会对焚烧设备造成很大的腐蚀，缩短焚烧设备的寿命；回灌是将浓缩液直接注入垃圾填埋厂，但是回灌会导致渗滤液中的溶解盐类和难降解有机物大量累积，从而导致整个渗滤液处理系统不稳定。蒸发工艺是将浓液中的水直接蒸干，该方法处理彻底，但是该工艺运行费用较高且装置投资大。高级氧化法包括电极氧化、光催化氧化、臭氧氧化法和Fenton氧化法等，该方法能够产生极强氧化能力的羟基自由基，能够无选择性的将水体中的有机物氧化为二氧化碳和水，但是运行成本较高，同时不能解决出水总氮超标的问题。At present, the main methods for treating landfill leachate nanofiltration concentrate at home and abroad are: backspray incineration, recharge, advanced oxidation and evaporation. There are many disadvantages in backspray incineration, not only loss of combustion calorific value, but also great corrosion to incineration equipment, shortening the life of incineration equipment; backfilling is to inject the concentrated liquid directly into the landfill plant, but backfilling will lead to leachate The dissolved salts and refractory organic matter in the leachate accumulated in a large amount, which led to the instability of the entire leachate treatment system. The evaporation process is to directly evaporate the water in the dope to dryness. This method is thorough, but the operating cost of this process is high and the equipment investment is large. Advanced oxidation methods include electrode oxidation, photocatalytic oxidation, ozone oxidation, and Fenton oxidation. The operating cost is high, and at the same time, it cannot solve the problem that the total nitrogen in the effluent exceeds the standard.
