技术领域 technical field
本发明涉及厌氧/好氧/氯气消毒领域，具体为一种生活污水处理装置。 The invention relates to the field of anaerobic/aerobic/chlorine gas disinfection, in particular to a domestic sewage treatment device.
背景技术 Background technique
生活污水的处理主要是处理水质中的有机物，COD作为有机物相对含量的一项综合指标，所以测量水质的COD即可看出水质质量，COD越大，水体污染越严重。目前，生活污水处理方法主要有物化处理法和生物处理法。物化处理法是应用物理化学作用及其原理将废水中的污染物成分转化为无害物质，使废水得到净化的方法，如化学氧化法和膜分离法等；生物处理法是利用微生物降解水中的污染物质作为自身的营养和能源，同时使废水得到净化的方法。生物法处理生活污水的主要方法有厌氧生物处理、好氧生物处理。 The treatment of domestic sewage is mainly to deal with the organic matter in the water quality. COD is a comprehensive indicator of the relative content of organic matter. Therefore, the water quality can be seen by measuring the COD of the water quality. The greater the COD, the more serious the water pollution. At present, domestic sewage treatment methods mainly include physical and chemical treatment and biological treatment. Physicochemical treatment is a method of converting pollutants in wastewater into harmless substances by applying physical and chemical effects and principles, such as chemical oxidation and membrane separation; biological treatment is the use of microorganisms to degrade pollutants in water. Pollutants are used as their own nutrients and energy sources, while the wastewater is purified. The main methods of biological treatment of domestic sewage are anaerobic biological treatment and aerobic biological treatment.
厌氧折流板反应器（ABR）是上世纪80年代开发的一种高效厌氧反应器，ABR是一个由多隔室组成的高效新型反应器，ABR反应器是一种连续流的多隔室结构，污水依次流经各隔室而得到降解，反应器每个隔室都有一个厌氧污泥层，其功能与UASB反应区类似，不同的ABR反应器不设置三相分离器。其工艺既有生物截留能力强、运行管理方便、性能可靠等优点。但ABR反应器作为厌氧生物处理工艺的一种，具有厌氧生物处理的共性，即对有机物虽然有着较高的处理率，但反应器出水中仍就含有大量有机物，出水不能达到排放标准，往往在厌氧反应器后需要加好氧处理，进一步去除厌氧反应器出水的有机物。 Anaerobic Baffled Reactor (ABR) is a high-efficiency anaerobic reactor developed in the 1980s. ABR is a high-efficiency new reactor composed of multiple compartments. The structure of the chamber, the sewage flows through each compartment in turn to be degraded, each compartment of the reactor has an anaerobic sludge layer, its function is similar to that of the UASB reaction zone, different ABR reactors do not have a three-phase separator. The process has the advantages of strong biological interception capacity, convenient operation and management, and reliable performance. However, as a kind of anaerobic biological treatment process, the ABR reactor has the commonality of anaerobic biological treatment, that is, although it has a high treatment rate for organic matter, the effluent of the reactor still contains a large amount of organic matter, and the effluent cannot meet the discharge standard. It is often necessary to add aerobic treatment after the anaerobic reactor to further remove the organic matter in the effluent of the anaerobic reactor.
