Description
Technical Field
The utility model belongs to the technical field of sewage treatment, and particularly relates to a biochemical pool heating system.
Background
In sewage treatment, the biochemical tank mainly utilizes the degradation effect of microorganisms to decompose organic pollutants in sewage. However, the activity of microorganisms is greatly affected by water temperature, and it is considered that the physiological activities of microorganisms are vigorous in the range of 15-30 ℃ and the capability of decomposing organic pollutants is strongest, and outside this temperature range, the oxidative decomposition reaction degree of activated sludge mainly composed of microorganisms is adversely affected. When the temperature is lower than 10 ℃, the metabolism function of the microorganism on the organic matters is obviously reduced; at the water temperature of 5 ℃, the microorganisms stop propagating, the organic pollutants are hardly decomposed, and the sewage treatment effect is greatly reduced.
On the other hand, in the sewage advanced treatment, ozone oxidation is often used as a sewage advanced treatment process. A large amount of heat is generated in the process of preparing ozone, the heat generated by circulating cooling water is required to be carried out of equipment, otherwise, the efficiency of an ozone generator is directly affected, and the running cost is increased. Specifically, the high-voltage discharge ozone generator used for ozone oxidation consists of external circulating cooling water and an internal circulating cooling water system, wherein the temperature of the external circulating water is less than 32 ℃, the temperature of the internal circulating water is less than 39 ℃, and the temperature rise DeltaT of inlet water and outlet water is less than or equal to 4 ℃. In order to ensure the water temperature index (especially the high temperature in summer) of the external circulating water, an external circulating water chilling unit is generally additionally arranged, and the external circulating water temperature is reduced.
In the sewage biochemical tank, in order to ensure the sewage biochemical treatment effect, the sewage needs to be heated under the condition that the water temperature of the sewage tank is too low. The conventional heating modes include steam, hot water and electric heating, but the heating modes consume energy sources, and directly increase the sewage treatment cost.
