Embodiment Construction

[0019] exist figure 1 Among them, the solar heat collector 1 adopts a vacuum type solar heat collector, and its function is exactly to obtain solar energy. The solar heat collector outlet pipe 2 is made of a steel pipe, and its effect is to deliver high-temperature water to the heating water tank 4. The solar heat collector return pipe 3 is made of a steel pipe, and its effect is to send back the low-temperature water in the heating water tank 4 li to the solar heat collector 1 li for heating. The heating water tank 4 is welded by steel plates, and is two layers inside and outside, and heat insulating material is filled in the interlayer, to reach the purpose of water tank insulation.

[0020] Components such as the solar heat collector 1 and the heating water tank 4 form a solar heat collection heat storage system, and the function of the system is to obtain solar energy and store it for later use.

[0021] A working medium generator 5 and B working medium generator 6 are a...

Abstract

The invention provides a solar-energy membrane bioreactor, which uses directly solar energy for heat-machine conversion, and completes dissolved-oxygen aeration and membrane reverse osmosis compression process without motor, fan and pump. This invention cuts cost greatly and has wide application.

Description

technical field [0001] The invention relates to solar energy utilization and sewage purification treatment, in particular to a solar membrane bioreactor. Background technique [0002] In the case of increasingly scarce water resources in our country, the recycling of sewage has become the main way to solve the urban water shortage and the main means to reduce water pollution. Membrane bioreactor, as one of the advanced technical methods for sewage purification and reuse, has been generally recognized and favored by experts and professors in the water treatment industry. This advanced technical method combines traditional water treatment technology and modern water treatment technology. Together, it has formed a unique technical advantage. It not only biodegrades sewage, but also performs membrane reverse osmosis treatment, which minimizes environmental pollution and improves the quality of purified water. technical support. However, due to the high en...
