Description
Technical Field
The invention relates to the technical field of sewage treatment, in particular to a sewage plant equalizing basin pressurization pumping unpowered control energy-saving system.
Background
Whether it is industrial wastewater, municipal wastewater or domestic wastewater, the amount of wastewater discharged is not uniform within 24 hours. Generally, the fluctuation of industrial wastewater is larger than that of municipal sewage, and the fluctuation of medium and small-sized plants is larger. Such changes are very detrimental to the normal functioning of the wastewater treatment plant, and may even cause the wastewater treatment system to be paralyzed. Therefore, a surge and conditioning facility, i.e., a conditioning tank, is typically provided before the wastewater treatment system to ensure proper operation of the system.
Similarly, sewage plants in small towns and towns also have the same problems of industrial wastewater plants, and the stable operation of the sewage plants is influenced due to small design scale and large fluctuation of water inflow amount. The periodicity of the water consumption of small towns is obvious, and particularly, in small-scale sewage treatment plants mainly treating domestic sewage, water quantity regulation measures are also considered in the small-scale sewage treatment plants, and the similar sewage treatment plants can regulate the water quantity according to needs, namely, a water quantity regulation pool is arranged.
The regulation time of industrial sewage plants and sewage treatment plants in small towns is usually 4-6 h, or longer regulation time is set according to different sewage properties. The sewage plant booster pump generally adopts a submersible sewage pump, and a submersible sewage pump (not a separately arranged collecting tank) is arranged in a regulating tank to pressurize and lift sewage into a next-stage treatment structure.
The effective water depth of the adjusting tank of the sewage plant is generally 3-5m, and when the sewage plant enters the adjusting tank from the upper-level treatment structure, the sewage plant is generally lifted after water drop, so that the phenomena of energy head waste and energy conservation are avoided. The main defects of regulation and pressurization of the existing sewage plant are that water from a structure on a regulating tank falls into the regulation and storage tank, water head waste exists, electricity consumption is wasted due to water fall repressurization, energy is not saved, and the sewage plant is uneconomical.
