Problems solved by technology
[0004] However, for sewage stations with small and medium water volumes such as village and town sewage, full-time personnel are set up to add carbon sources every day, and large municipal sewage treatment plants add carbon sources. Both labor costs and carbon source costs are very high, which is not conducive to saving water pollution treatment costs.

The invention discloses an energy-saving nitrogen and phosphorus removal integrated treatment biological purification tank which comprises a front anoxic and anaerobic precipitation tank, an access hole cover plate is installed at the top of the front anoxic and anaerobic precipitation tank, a water inlet pipe is installed in the front anoxic and anaerobic precipitation tank in a penetrating mode, one end of the water inlet pipe is connected with a lifting pipe, a lifting pump is connected to the bottom of the lifting pipe in a penetrating mode, a suction pipe is installed on the side face of the lifting pump in a penetrating mode, and an end aerator pipe is connected to the interior of the front anoxic and anaerobic precipitation tank in a penetrating mode; a first water pipe is installed in the front anoxic and anaerobic precipitation tank in a penetrating mode, one end of the first water pipe is connected with a first aerobic and anoxic precipitation tank, a second water pipe is installed in the first aerobic and anoxic precipitation tank in a penetrating mode, and one end of the second water pipe is connected with a second aerobic and anoxic precipitation tank. Chemical auxiliary phosphorus removal is configured on a pipeline before sewage enters a sedimentation clarification tank, so that the controllability of total phosphorus is stable and reaches the standard.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an energy-saving biological purification tank for integrated treatment of nitrogen and phosphorus removal. Background technique [0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] The problem of denitrification is the main problem of sewage treatment at present. Domestic denitrification needs to be solved by adding carbon source to the anoxic pool or denitrification filter. Carbon source personnel. For large municipal sewage treatment plants, automatic dosing is realized through fixed ope...
