Problems solved by technology
[0002] When biochemical treatment is used to treat sewage in alpine regions, there are the following problems: the inlet temperature of sewage biochemical treatment facilities is low, especially in winter, far below the 10-12 ℃ required for biological treatment, and it is difficult to meet the standards for biochemical treatment
If the sewage is firstly heated by simple heating, and then transported to the biochemical treatment tank for treatment, there will be a problem of high energy consumption

Embodiment Construction
[0027] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0028] The present invention provides a decentralized sewage station effluent temperature recycling heating energy-saving system, which is applied to sewage treatment in alpine or northern regions, and the high-temperature effluent discharged from sewage facilities is recycled to the front-end heat exchange device through a circulating water pump Heat exchange is carried out to increase the temperature of the sewage inlet water, and the use of residual temperature recycling technology greatly reduces energy consumption and achieves the purpose of practical energy saving. ...

The invention provides a distributed sewage station effluent waste heat recycling heating energy-saving system and method. A preheating water tank, a heating water tank, a biochemical treatment tank, an intermediate water tank and a drainage tank are sequentially arranged from front to back; a heat exchange device is arranged in the preheating water tank; a liquid level meter and a circulating water pump are arranged in the middle water tank; the circulating water pump is communicated to a water inlet of the heat exchange device through a first water conveying pipeline; and a water outlet of the heat exchange device is communicated to the water drainage tank through a second water conveying pipeline. The invention provides a distributed sewage station effluent waste heat recycling heating energy-saving system which is applied to sewage treatment in high and cold areas or northern areas, high-temperature effluent discharged by sewage facilities is recycled to a front-end heat exchange device through a circulating water pump for heat exchange, the temperature of sewage inlet water is increased, energy consumption is greatly reduced through the waste heat recycling technology, and practical and energy-saving purposes are achieved.
Description
technical field [0001] The invention belongs to the technical field of waste heat utilization, and in particular relates to an energy-saving system and method for reusing and heating the waste water of a distributed waste water station. Background technique [0002] When biochemical treatment is used to treat sewage in alpine regions, there are the following problems: the inlet temperature of sewage biochemical treatment facilities is low, especially in winter, far below the 10-12 °C required for biological treatment, and it is difficult to meet the standards for biochemical treatment. If the sewage is firstly heated by simple heating, and then transported to the biochemical treatment tank for treatment, there will be a problem of high energy consumption. Contents of the invention [0003] In view of the defects existing in the prior art, the present invention provides a decentralized waste water station outlet water heating and energy-saving system and method, which can e...
