Ways to solve water pollution

The ways to improve water quality generally include:

1, source water protection;

2. Renovation of process equipment in waterworks;

3. Water supply by pipeline;

4. Water purification of household pipe network terminal.

In order to control water pollution, it is necessary to prohibit the development of industries with serious pollution in the watershed of water source areas, so as to reduce the emission of pollutants. However, from the current economic development momentum and the actual situation of relevant national laws, regulations and enforcement, it is a very serious issue to improve the water quality of water sources in a short time, and there will be a long process.

The renovation of waterworks can improve the quality of tap water to a certain extent, but it cannot fundamentally solve the problems, especially the secondary pollution of pipelines. From the current situation of our country, it can be predicted that the renewal of equipment and technology of waterworks and the overall transformation of water pipe network will be difficult to achieve in 10-20 years.

There are many problems in engineering cost, design and construction, management and maintenance, water charge, hygiene index and safety degree, etc. In addition, the pipeline water supply can only be aimed at newly-built buildings. For a large number of existing residential quarters, the water pollution problem cannot be solved because of the re-laying of pipelines.

According to the research of the International Health Organization, the most effective way to enjoy healthy water is to install a water purifier at the end of the municipal water supply pipe network, that is, the household water terminal, which can fundamentally solve the secondary pollution problem of the tap water pipeline. Moreover, through the advanced treatment of the terminal, it is the supplement and perfection of the urban tap water treatment process, thus greatly improving the tap water quality as a whole, which can not only meet the needs of household drinking water, but also meet the needs of household eating, bathing, washing and many other aspects in all directions. From the engineering point of view, no matter the cost, construction difficulty, management and maintenance, use cost, hygiene index and safety degree, adopting home terminal water purifier is the best choice to solve water pollution. Even in western developed countries where tap water can be drunk, 70% of households have installed household terminal water purifiers in order to avoid secondary pollution of the pipeline network.
