Description

technical field [0001] The invention belongs to the field of water purification devices to be treated, and in particular relates to a carbon sand double-layer filter enhanced water filtration system based on biological activated carbon. Background technique [0002] At present, my country's urban waterworks generally adopt the chlorine oxidation disinfection process, which plays an important role in ensuring the quality of drinking water, but it cannot effectively remove trace soluble organic pollutants in the source water, and its chlorination disinfection process Many halogenated organic substances have been produced in the environment, many of which are carcinogenic, teratogenic, and mutagenic substances. Powdered activated carbon has a good effect on reducing the chroma, volatile phenol, odor and taste of polluted source water, and has a good effect on COD Mn It also has a better removal effect. After being adsorbed by powdered activated carbon, the types of environment...
