In fact, whether it is Anhui integrated living sewage treatment equipment or other areas of the equipment, sewage treatment is a gradual process, the need for professional staff to maintain, and the situation is different in different terrains, the equipment can alleviate water pollution in local areas, but there is no way to quickly manage water pollution.
There are several reasons for this:
1, integrated domestic sewage treatment device is only a small part of the sewage treatment system, if the front-end sewage is not collected, it is difficult to solve the problem of water pollution.
Any set of sewage treatment system, it is necessary to establish a relatively complete sewage collection system. Town sewage treatment in the need for large-scale construction of sewage pipe network, and in small domestic sewage treatment projects also need to do a good job of sewage collection. Sewage project treatment is not a once-and-for-all project, to ensure long-term stable operation, the need for professional operation and maintenance management of the network.
2, conventional domestic sewage treatment plant is not suitable for mountainous and northwestern regions, economically less developed areas can not even afford.
The current cost of domestic sewage treatment plant is generally higher, the more economical AO process of domestic sewage treatment plant is still 5000 yuan / ton, MBR sewage treatment plant and a combination of process devices more expensive, if there is no government funding, the project simply can not be established. In addition to the lack of water resources in central and western China, the concentration of domestic sewage is high, we are familiar with a variety of domestic sewage treatment devices in the technical principles of the level is difficult to solve.
3, the stable operation of the domestic sewage treatment plant depends on professional operation and maintenance, and the cost is not low, the restoration of water ecology needs a long time.
Life wastewater treatment project is usually a long time, with the passage of time equipment failure rate will be enhanced, the water quality effect will also decline. Professional operation and maintenance personnel need to regularly debug the parameters of the equipment, sludge cleaning, add bacteria and pharmaceutical fillers. The restoration of water ecology is a long process, control point source, surface source pollution, promote regional governance, watershed management, multi-pronged, precise policy is the future trend of water environment management.
