Solar thermodynamic cycle sewage treatment device

Abstract

The invention discloses a solar thermodynamic cycle sewage treatment device which comprises trough type solar energy, an air supplementing tank, an aeration tank, a temperature increasing tank and a settling tank, wherein the trough type solar energy is rotatably connected with the air supplementing tank, one end of the aeration tank is connected with the air supplementing tank through a pipeline,and the other end of the aeration tank is connected with the temperature increasing tank through a pipeline; and the other end of the temperature increasing tank is connected with the settling box through a pipeline. Trough type solar energy provides power for pumping outside air for the air supplementing box through high-temperature steam, power generation power is provided for the power generator through high-temperature steam again, the aeration box provides air through the air supplementing box to aerate sewage, more oxygen is provided for sewage microbiological treatment, and meanwhile,the temperature increasing tank utilizes heat of high-temperature steam to heat sewage, the activity of microorganisms in water is improved, the sewage treatment efficiency is improved, and the sewagetreatment device has the effect of efficiently treating sewage.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a solar thermal cycle sewage treatment device. Background technique [0002] With the continuous advancement of my country's urbanization process, the problem of water pollution has become increasingly prominent. However, due to the differences in natural conditions, living habits and economic development in various regions of our country, it is necessary to formulate different plans according to the specific status quo of different regions. , and considering the different water quality, water volume and discharge destination of each region to determine the sewage treatment technology according to local conditions, it will undoubtedly increase the workload, treatment difficulty and capital investment. [0003] With the increasingly prominent problem of water pollution, the method of purifying sewage by utilizing the physiological function synergy between microalgae and ba...

Problems solved by technology

[0006] Moreover, in recent years, the effect of magnetic field on sewage biodegradation has received more and more attention. Many studies have shown that magnetic field can greatly improve wastewater biodegradation The efficiency is conducive to improving the efficiency of sewage biological treatment and improving the shortcomings of large area occupied by biochemical treatment facilities

[0007]The existing biofilm sewage treatment technology is driven by electric energy, which consumes a lot of energy; temperature affects the metabolism of algae and bacteria, thus affecting the efficiency and stability of sewage treatment

The current bacteria and algae treatment device is easily affected by temperature in the sewage treatment process, the sewage treatment efficiency is not high, and the performance stability is poor, which seriously restricts the promotion and application of this technology

Especially in the north, due to climatic factors that directly affect the operation of the reactor, the internal temperature cannot be kept constant, which affects the stability of its operation, and cannot guarantee that it will react under the best conditions
