Description
技术领域 technical field
本实用新型属于污水处理技术，尤其涉及一种污水处理的中水回用系统。The utility model belongs to the sewage treatment technology, in particular to a reclaimed water reuse system for sewage treatment.
背景技术 Background technique
传统的污水处理技术是采用前置处理、生化处理和后处理三过程将需要处理的污水处理达到国家或当地排放指标后，就将处理后的污水排放掉，这样失去了水资源再次利用的价值，不利于循环经济的发展。中水回用技术的发明和使用是当前解决水资源循环利用的重要课题。膜生物反应器（MBR）是一种由膜分离单元与生物处理单元相结合的新型水处理技术，由于MBR将传统污水处理的曝气池与二沉池合二为一，并取代了三级处理的全部工艺设施，因此可大幅减少占地面积，节省土建投资。与传统的生化水处理技术相比，MBR具有以下主要特点：处理效率高、出水水质好；设备紧凑、占地面积小；易实现自动控制、运行管理简单。“以膜组件取代二沉池在生物反应器中保持高活性污泥浓度减少污水处理设施占地”为代价，带来的缺点膜堵塞后清洗膜非常麻烦、对入水水质要求较高，故应用在工业污水处理突显成本较高。The traditional sewage treatment technology uses three processes of pre-treatment, biochemical treatment and post-treatment to treat the sewage to be treated after reaching the national or local discharge indicators, and then discharge the treated sewage, which loses the value of water resources reuse , is not conducive to the development of circular economy. The invention and use of reclaimed water reuse technology is an important issue to solve the recycling of water resources. Membrane bioreactor (MBR) is a new type of water treatment technology that combines a membrane separation unit with a biological treatment unit. Since MBR combines the aeration tank and the secondary sedimentation tank of traditional sewage treatment into one, it replaces the three-stage All the process facilities are processed, so the floor area can be greatly reduced and the civil construction investment can be saved. Compared with the traditional biochemical water treatment technology, MBR has the following main features: high treatment efficiency, good effluent quality; compact equipment, small footprint; easy to realize automatic control, simple operation and management. At the cost of "replacing the secondary settling tank with membrane modules to maintain a high concentration of activated sludge in the bioreactor and reducing the land occupation of sewage treatment facilities", the shortcomings brought about by the membrane blockage are very troublesome to clean the membrane, and the requirements for the quality of the influent water are high, so the application The high cost of industrial sewage treatment is highlighted.
