Sewage is very common in production and life. It not only pollutes the environment, but also endangers people's health. Therefore, we need to use decontamination equipment to further repair, we can learn from the practice of life is that domestic sewage treatment equipment in many areas are useful, its wide range is easy to deal with a variety of complex pollution basic magic weapon, the key lies in the governance, its operation cost output is not high, and indeed is low cost and high efficiency. Besides, it has many advantages. For example, the whole equipment is very compact and does not take up too much surface area. It is also particularly effective in the quality, stability, separation and removal of effluent water. Therefore, this natural decision of the surplus sludge production is also very small, will not use too much manpower and material resources. It will give you a lot of free time, which is no doubt in the processing effect, can be removed easily degraded, more convenient and efficient operation and management. In fact, the most important thing is that it is not clear about the traditional process, some kind of transformation, application, etc. . It is important to understand that domestic sewage treatment equipment, which mainly deals with domestic sewage and similar industrial waste water, can be used to treat sewage efficiently. It is also considered to be one of the main methods of wastewater treatment to date, using physical filtration, biodegradation and plant retention techniques to effectively remove organic matter. Certain substances can also be removed through a combination of aquatic plants and microorganisms, especially through treatment and reuse. This in part promotes the clean water system of domestic sewage, rivers and natural lakes.
