1, water source water protection: in order to control water pollution, should be prohibited within the watershed of the water source to develop heavily polluting industries to reduce the discharge of pollutants. But from the momentum of the current economic development and the actual situation of the relevant national laws and regulations and the implementation of the strength of the water in the short term to improve the quality of water is a very serious subject, there will be a long process.
2, the water plant process equipment transformation: the transformation of the water plant can improve the quality of tap water to a certain extent, but can not fundamentally solve the problem, especially the pipeline of the secondary pollution problem. And transformation costs are huge, from the point of view of China's current national conditions, it can be predicted that the water plant equipment and technology updates and the overall transformation of the water pipeline network in 10-20 years is difficult to achieve.
3, pipeline quality water supply: the use of pipeline quality water supply, because of its engineering costs, design and construction, management and maintenance, water charges, health indicators and safety and so on, there are many problems. In addition, the pipeline quality water supply can only be for new buildings, for our existing large number of residential areas, due to the re-laying of the pipeline involved in the problem of water pollution still can not be solved.
4, the family network terminal water purification: the International Health Organization research shows that the most effective way to enjoy the health of the water in the municipal water supply network at the end of the family water terminal installed a purified tap water purifier.
