Particle microalgae system for mariculture wastewater treatment

Abstract

The invention discloses a particle microalgae system for mariculture wastewater treatment. The particle microalgae system comprises a microalgae reactor, and the microalgae reactor is communicated with a water inlet tank and a microalgae collecting tank through a conveying part and a control part; the microalgae reactor comprises a microalgae reaction tank and a microalgae storage tank, the bottom end of the microalgae reaction tank is fixedly connected with the top end of the microalgae storage tank, the microalgae reaction tank is communicated with the microalgae storage tank, the water inlet end of the microalgae reaction tank is communicated with the water inlet tank, and the microalgae storage tank is communicated with the microalgae collection tank; two baffles are oppositely arranged in the microalgae reaction tank, are fixedly connected with the side wall of the microalgae reaction tank, and are matched with the microalgae reaction tank to form a middle compartment and two side compartments. The problems that in an existing microalgae membrane reactor, microalgae particles are prone to disintegration, low in activity and poor in settleability, biomass is not prone to being collected and the like can be solved, the microalgae particles in a good state are cultured, and meanwhile the purpose that the particle microalgae membrane bioreactor efficiently treats mariculture wastewater is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a granular microalgae system for mariculture wastewater treatment. Background technique [0002] Membrane bioreactor has the dual advantages of efficient removal of pollutants and clean output. The combination of biological reaction system and flat membrane module can effectively ensure the stability of effluent water quality and system treatment efficiency; at the same time, it can realize efficient mud-water separation process and ensure the reactor The relatively high sludge concentration is conducive to improving the environmental impact resistance of the sludge system, especially in seawater environments with high salinity and complex chemical composition, which has great application potential and is the most attractive in the field of marine ecological environmental protection. one of the subjects. [0003] Microalgae treatment of sewage can realize resource utili...
