A three-baffle plate reactor for marine aquaculture wastewater treatment and microalgae cultivation and harvesting

Abstract

The invention discloses a three-baffle plate reactor for the treatment of marine aquaculture wastewater and the cultivation and harvesting of microalgae. Each stage of the fluidized bed reactor is provided with a circular arc bottom plate and an aeration plate, and the aeration plate is an inverted "Y"-shaped structure. , the aeration plate includes a fixedly connected main plate and two side plates, the two side plates are fixedly connected with the arc bottom plate, the highest point of the main plate is lower than the highest point of the isolation plate; the water-lifting side of the main plate and the water supply side of the two side plates There are aeration holes on the top, and through holes are opened on the two side plates; the first two-stage circular arc bottom plates are fixedly connected with the bottom plate of the fluidized bed reactor, and the last level circular arc bottom plate and the bottom plate of the fluidized bed reactor are fixedly connected. An enrichment cavity is arranged, and a hollow fiber membrane assembly is arranged on the side of the main board in the last stage away from the isolation plate. On the basis of treating marine aquaculture wastewater, the invention solves the problems of low microalgae cultivation efficiency, difficulty in harvesting and the like, and realizes the purpose of simultaneous treatment and harvesting.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a three-baffle plate reactor for the treatment of marine aquaculture wastewater and the cultivation and harvesting of microalgae. Background technique [0002] Membrane bioreactor wastewater treatment technology has been developed for more than 30 years. Traditional membrane bioreactors use activated sludge as the main microorganism for wastewater treatment. It has the advantages of small footprint, high sludge concentration, good effluent quality, and low biological treatment cost, and has been widely used. Microalgae, as photoautotrophic organisms with strong production capacity, can effectively convert CO2, nitrogen, phosphorus, etc. into their own biomass through assimilation, and microalgae can be used as raw materials for bioenergy production, bait for aquatic products, Human health food is widely used in various industries. [0003] The combination of ...
