Description
技术领域 technical field
本发明涉及一种垃圾中转站渗滤液处理与回用方法。The invention relates to a method for treating and reusing leachate in a garbage transfer station.
背景技术 Background technique
CN200910111323.7公开了“一种垃圾渗滤液零排放回用处理方法”，它的目的是利用物化、生化、膜过滤联用技术，提供一种垃圾渗滤液零排放回用处理方法。该发明申请的技术方案是：将垃圾渗滤液原液送入原水调节池，出水经膜混凝反应器去除悬浮固体和杂质，膜混凝反应器的反冲洗出水回流至原水调节池，排出的废水进入膜接触反应器，形成副产品硫酸铵溶液；膜接触反应器出水进入升流式厌氧生物反应器，进行厌氧生化处理，将升流式厌氧生物反应器的出水送入膜生物反应器进行好氧生化处理；将膜生物反应器的出水送入连续膜过滤系统进行过滤，将连续膜过滤系统的浓缩液和反冲洗水回流至原水调节池；将连续膜过滤系统的出水送入反渗透系统，将反渗透系统的浓缩液经锅炉氧化喷烧去除，反渗透系统的出水即为可回用的纯水。其不足之处是：反渗透系统的使用，增加设备的维护难度，投资成本高，而产生的浓缩液也增加后续处理的工作量。氨氮和有机物的去处一大部分靠物理化学方法分离而非生物方法，加药量大，增加了运行成本。CN200910111323.7 discloses "a treatment method for zero discharge and reuse of landfill leachate", which aims to provide a treatment method for zero discharge and reuse of landfill leachate by using combined technologies of physicochemical, biochemical and membrane filtration. The technical solution of this invention application is: send the stock solution of landfill leachate into the raw water adjustment tank, remove the suspended solids and impurities from the effluent through the membrane coagulation reactor, return the backwash effluent from the membrane coagulation reactor to the raw water adjustment tank, and discharge the waste water Enter the membrane contact reactor to form a by-product ammonium sulfate solution; the effluent from the membrane contact reactor enters the upflow anaerobic bioreactor for anaerobic biochemical treatment, and the effluent from the upflow anaerobic bioreactor is sent to the membrane bioreactor Carry out aerobic biochemical treatment; send the effluent of the membrane bioreactor to the continuous membrane filtration system for filtration, return the concentrate and backwash water of the continuous membrane filtration system to the raw water adjustment tank; send the effluent of the continuous membrane filtration system to the reverse Osmosis system, the concentrated solution of the reverse osmosis system is oxidized and burned by the boiler to remove it, and the effluent of the reverse osmosis system is pure water that can be reused. Its disadvantages are: the use of reverse osmosis system increases the difficulty of equipment maintenance, high investment cost, and the concentrated solution produced also increases the workload of subsequent treatment. Most of the removal of ammonia nitrogen and organic matter is separated by physical and chemical methods rather than biological methods, and the amount of dosing is large, which increases the operating cost.
