Abstract

The invention discloses an autogiration-type anaerobic positive penetration membrane penetration membrane bioreactor, and applications thereof, and belongs to the technical field of sewage processing.A processing method comprises following steps: raw water is introduced into an anaerobic reaction zone through a water inlet pump, generated biogas is subjected to water sealing and collecting recycling; a part of sewage is subjected to separation purifying under the effect of a FO membrane, and is subjected to processing recycling using a RO membrane; the other part of sewage is delivered through a MF membrane for separation purifying. According to the autogiration-type anaerobic positive penetration membrane penetration membrane bioreactor, a blade type FO membrane assembly is fixedly arranged on a rotating shaft, and is pushed to perform rotation motion under the effect of inlet water flow, so that transmission effect is improved, FO membrane pollution is alleviated, and reactor operation time is prolonged; the MF membrane is adopted to control salinity accumulation; reactor occupied space is small; organic matters in sewage are recycled in the form of biogas; and automatic controlof the whole system is realized.

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...
