Description

technical field [0001] The invention relates to the technical field of water purification devices, in particular to an energy-saving and environment-friendly water purification device for waterworks. Background technique [0002] At present, with the development of China's industry, the spread of air pollution and the use of pesticides in recent years have caused the quality of domestic water to decline year by year while the economy is developing. The traditional water purification method of waterworks is to use it in pools or tanks. The flocculant is flocculated and precipitated, and then passed into the filter tank, filtered through the filter medium, and then disinfected with a disinfectant. This water purification method is not only cumbersome to operate, but also the flocculant and disinfectant used are chemical reagents. The use cycle is short, and there are many by-products. While purifying water, it also brings chemical pollution. Therefore, in order to improve peo...
