Embodiment Construction

[0020] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] combine figure 1 As shown, the solar photovoltaic power generation integrated membrane bioreactor integrated device in this embodiment includes anoxic tank 1 , aerobic tank 2 , membrane module 3 , heating plate module 4 and solar photovoltaic power generation unit 5 .

[0022] An anoxic tank 1 is provided with a liquid inlet pipe 6 for introducing sewage to be treated. With the help of heterotrophic bacteria growing in the anoxic tank, suspended pollutants such as starch, fiber, and carbohydrates and soluble organic matter in sewage can be hydrolyzed into organic acids, macromolecular organic matter is decomposed into small molecular organic matter, and insoluble organic matter is converted into soluble organic matter.

[0023] The aerobic tank 2 is located downstream of the anoxic tank 1 , and the two are communicat...

Abstract

The invention belongs to the technical field of membrane bioreactors. In order to solve the problems of impact damage of large aeration rate to a membrane assembly, high cost and high energy consumption in the operation process of an existing membrane bioreactor, the invention discloses a solar photovoltaic power generation combined membrane bioreactor integrated device. The device comprises an anoxic tank, an aerobic tank, a membrane assembly, a heating plate assembly and a solar photovoltaic power generation unit. The anoxic tank is provided with a liquid inlet pipe, the aerobic tank is located at the downstream of the anoxic tank and is communicated with the anoxic tank through a connecting pipe, and liquid in the anoxic tank is guided into the aerobic tank. A heating plate is located in the anoxic tank, and the solar photovoltaic power generation unit is connected with the heating plate to provide electric energy to drive the heating plate assembly to release heat. The membrane assembly is positioned in the aerobic tank, and the aerobic tank is also provided with a water outlet pipe for leading out water treated by the membrane assembly. By adopting the solar photovoltaic powergeneration combined membrane bioreactor integrated device disclosed by the invention, the protection on the membrane assembly can be improved, and the cost and the energy consumption are reduced.

Description

technical field [0001] The invention belongs to the technical field of membrane bioreactors, and in particular relates to an integrated device of solar photovoltaic power generation combined with membrane bioreactors. Background technique [0002] In existing membrane bioreactors, in order to reduce and slow down membrane fouling, the method of adding adsorbents is usually used to remove organic matter, thereby reducing the amount of organic matter entering the membrane module, reducing the resistance of the filter cake layer, and reducing membrane fouling. This method Not only the effect is quick, but membrane fouling can be slowed down, and large-scale transformation is not required. Especially when sewage treatment is carried out in an environment with low water temperature in winter, the effluent water quality will not meet the standard due to the decrease of microbial activity and the decrease of reactor operating efficiency. Multi-organic matter is adsorbed and remove...
