According to monitoring, the national wastewater discharge increased from 310.50 billion tons in 1980 to 63/kloc-0.50 billion tons in 2002. Groundwater in most cities has been polluted to varying degrees, and it is getting worse year by year. The increasingly serious water pollution not only reduces the use function of water bodies, further exacerbates the contradiction of water shortage, but also seriously threatens the drinking water safety and health of urban residents.
Now the country is also trying to find ways to govern, but it takes a lot of time, money and manpower, and it is difficult to see results in a short time. Therefore, during this period, the health of drinking water depends on yourself. You can install a water purifier at home to keep the water clean and healthy. In addition, you should strengthen the awareness of protecting water resources and reduce water pollution.
