          • 生活污水处理设备选择的技巧

          生活污水的处理时一项需要大家重视的环境保护措施,在对生活污水进行处理时我们要采取什么样的措施呢?是怎么样一个操作模式呢?我们应该选用什么样的生活污水处理设备呢?   

                由于生活污水处理的核心是生化部分,因此我们称污水处理工艺是特指这部分,如接触氧化法、SBR法、A/O法等。在采用用生化法(包括厌氧和好氧)处理生活污水的污水处理工艺,在处理时根据生活污水的水量、水质及现场的条件而选择不同的污水处理工艺对投资及运行成本具有决定性的影响。多年以来,城市中生活污水的二级生物处理多采用活性污泥法,它是当前世界各国应用一种二级生物处理流程,具有处理能力高,出水水质好等优点。

                 目前在城市生活污水处理研究和应用领域,普遍存在的问题有: 

                (1)采用传统的活性污泥法,往往基建费、运行费高,能耗大,管理较复杂,易出现污泥膨胀现象;

                (2)随着污水排放标准的不断严格,对污水中氮、磷等营养物质的排放要求较高,传统的具有脱氮除磷功能的污水处理工艺多以活性污泥法为主,往往需要将多个厌氧和好氧反应池串联,形成多级反应池,通过增加内循环来达到脱氮除磷的目的,这势必要增加基建投资的费用及能耗,并且使运行管理较为复杂。 

                (3)目前城市污水的处理多以集中处理为主,庞大的污水收集系统的投资远远超过污水处理厂本身的投资,因此建设大型的污水处理厂,集中处理生活污水。许多地方开始采用生活污水处理设备,对污水有一个很好的处理。   

                采用合适的生活污水处理设备,让我们的生活污水得到有效的处理,让我们的生态环境可持续发展,也给我们提供了一个安全健康的生活环境。

          The treatment of domestic sewage is an environmental protection measure that needs everyone's attention. What kind of measures should we take when we treat domestic sewage? What is the mode of operation? What kind of domestic sewage treatment equipment should we choose? As the core of domestic sewage treatment is the biochemical part, so we call the sewage treatment process refers to this part, such as contact oxidation, SBR, a / O, etc. . In a wastewater treatment process using biochemical processes including anaerobic and aerobic treatment of domestic wastewater, according to the quantity, quality and site conditions of domestic sewage, the choice of different sewage treatment process has a decisive impact on investment and operation cost. For many years, the secondary biological treatment of domestic sewage in cities mostly uses activated sludge, which is a secondary biological treatment process applied in the world at present, and has the advantages of high treatment capacity and good effluent quality. At present, in the field of research and application of municipal domestic sewage treatment, the common problems are as follows: 1 using the traditional activated sludge, the capital cost and operation cost are often high, the energy consumption is large, the management is complex, the sludge bulking is easy to occur; 2 with the increasingly strict wastewater discharge standard, the demand for nitrogen, phosphorus and other nutrients in wastewater is higher, and the traditional wastewater treatment process with the function of nitrogen and phosphorus removal is mainly activated sludge, many anaerobic and aerobic reaction pools are often connected in series to form multi-stage reaction pools, and the purpose of nitrogen and phosphorus removal can be achieved by increasing internal circulation. 3 at present, the treatment of urban sewage is mainly concentrated treatment, the investment of huge sewage collection system far exceeds the investment of the Sewage Treatment itself, so the construction of large-scale Sewage Treatment, centralized treatment of domestic sewage. Many places began to use domestic sewage treatment equipment, sewage has a good treatment. By adopting proper sewage treatment equipment, we can effectively treat our sewage, make our ecological environment sustainable, and provide us with a safe and healthy living environment.
