Problems solved by technology
Assuming that all water is treated as highly polluted water will cause a lot of waste of energy consumption, assuming that all water is treated according to the treatment standard of low-polluted water, it is easy to cause the sewage treatment to fail to meet the standard

Embodiment Construction
[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0031] Such as figure 1 As shown, an energy-saving urban sewage treatment system includes a sewage diversion module 1 for diverting different sewage, a primary sedimentation tank 2 for precipitating impurities in water, an electrolytic tank 3 for treating heavy metal ions in wastewater, and a secondary sedimentation tank for re-precipitating impurities in water. Sedimentation tank 4, biological treatment tank 5 for treating organic matter in wastewater, coagulation sedimentation tank 6 for suspended impurities in sedimentation water, and filter tank 7 for filtering residual impurities in water. The sewage passes through the primary sedimentation tank 2, the electrolytic tank 3, the secondary sedimentation tank 4, the biological treatment tank 5, the coagulation sedimentation tank 6 and the filter tank 7 in sequence.
[0032] Such as figure 1 As shown, the s...

The invention relates to the technical field of sewage treatment, in particular to an energy-saving town sewage treatment system. The energy-saving town sewage treatment system comprises a sewage flowdividing module, a primary sedimentation pool, an electrolysis pool, a secondary sedimentation pool, a biological treatment pool for treating organic matter in wastewater, a coagulation sedimentationpool for sedimentation of suspended impurities in the water, and a filter pool for filtering residual impurities in the water; the sewage flow dividing module comprises a rainwater pipe assembly anda wastewater pipe assembly; the rainwater pipe assembly comprises a rainwater feeding pipe and a rainwater temporary storage pool connected with the rainwater feeding pipe; the side face, close to thebottom, of the rainwater temporary storage pool is connected with a rainwater discharging pipe which is connected with the primary sedimentation pool; and the side face of the upper end of the rainwater temporary storage pool is connected with an overflow pipe, and the overflow pipe is connected with the coagulation sedimentation pool. The water of different pollution degrees is conveyed to the different sewage treatment pools to be subjected to different treatment processes, excessive treatment of low-pollution water is avoided, and energy consumption is reduced.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an energy-saving urban sewage treatment system. Background technique [0002] Urban sewage also includes domestic sewage and industrial sewage, etc. For the discharge of industrial sewage, the state has formulated relevant standards, requiring enterprises that produce a large amount of sewage to have sewage treatment capabilities, and discharge can only be carried out after meeting the discharge standards; but there is no relevant standard for domestic water ; Domestic sewage is mainly treated by a sewage treatment plant; because domestic sewage contains a large amount of organic matter, the activated sludge method is generally used in the prior art for treatment. [0003] The core of the activated sludge method lies in the aeration tank and the sedimentation tank. The sewage mixed with sludge enters the aeration tank, and the organic matter in the sewage is eliminated t...
