Abstract

The invention relates to a process combination system for integrated treatment of micro-polluted raw water and a method of the process combination system. In a water inlet pre-oxidation area, an ozone adding point is arranged on a water inlet pipe, and after raw water is oxidized by ozone, alga and humic substances are oxidized; in a mechanical clarification area, the raw water is fully mixed by using mechanical stirring, so as to remove suspended matters, colloids and organic substances such as alga out of water; in an aerating biological filter area, alternating down-flow and up-flow biological filters are formed by virtue of a flow guide wall, so as to remove ammonia nitrogen, organic matters, odor, alga, turbidness and falling living bodies out of water; and in a sand filtering area, organic matters, bacteria, even viruses, and heavy metal substances such as iron and manganese in water are removed. The method and equipment for integrated treatment of micro-polluted raw water disclosed by the invention integrate a chemical oxidation method, a biological aeration filter method, a contact oxidation method, a biofilm process, a settling separation method and a rapid filtration method; and the processed water can reach the related national drinking water standards.

Description

technical field [0001] The invention relates to a treatment method for slightly polluted raw water, in particular to a combination of chemical oxidation, biological aerated filter method, contact oxidation method, biofilm method, sedimentation separation method and fast filtration method for treating slightly polluted raw water crafting system. Background technique [0002] In recent years, the problem of micro-pollution of drinking water sources in my country has become increasingly prominent, serious organic pollution, algae blooms, ammonia nitrogen exceeding the standard, and various plankton breeding. Therefore, how to upgrade the waterworks process on the basis of the existing process and explore advanced and efficient drinking water safety protection technology is an urgent problem to be solved in the water supply industry. [0003] Chemical pre-oxidation technology is to add chemical oxidants at the front end of the water treatment process, relying on its oxidation a...
