Abstract

The invention discloses a self-rotating anaerobic forward osmosis membrane bioreactor and an application thereof, belonging to the technical field of sewage treatment. The method of the present invention is aimed at organic waste water, comprising the following steps: the raw water enters the anaerobic reaction zone through the water inlet pump, and the biogas produced is collected and reused after being water-sealed; part of the sewage is separated and purified under the action of the FO membrane, and then passed through the RO Membrane treatment realizes reuse; another part of sewage is separated and purified by MF membrane. The invention fixes the blade-type FO membrane module on the rotating shaft, and pushes it to rotate through the power of the influent water flow, which not only improves the mass transfer effect, but also alleviates the pollution of the FO membrane and prolongs the running time of the reactor; through the MF membrane, the salt The degree of accumulation is controlled; the reactor occupies a small area, and the organic matter in the sewage is recovered in the form of biogas; the entire system can realize automatic control.

Description

technical field [0001] The invention relates to a self-rotating anaerobic forward osmosis membrane bioreactor and its application, belonging to the technical field of sewage treatment. Background technique [0002] In recent years, with the rapid development of the national economy, the discharge of domestic sewage and industrial wastewater is increasing. Industries represented by petroleum, chemical industry, papermaking, medicine, food, textile, etc. discharge a large amount of industrial wastewater. This type of wastewater has a high concentration of organic matter, complex components, and contains both biodegradable and non-degradable parts. Some Also contains toxic substances. Statistics show that the annual discharge of industrial wastewater exceeds 20 billion tons in general. If it is directly discharged into the water body without treatment, the water body will be polluted and pose a serious threat to human health and the ecological environment. Therefore, the trea...
