Abstract

The invention discloses a hollow fiber gravity-driven membrane reactor for treating algae-containing water and a use method thereof and relates to a membrane reactor and a use method thereof. The hollow fiber gravity-driven membrane reactor solves the problem that the existing gravity-driven membrane reactor has a large covering area and a high infrastructure construction cost. The hollow fiber gravity-driven membrane reactor comprises a head water tank, a water storage tank, a membrane reaction vessel, a collecting bottle, a weighing device, a gravity-type hollow fiber membrane module and a light source. The head water tank is arranged above the water storage tank. The water storage tank is arranged above the membrane reaction vessel. The light source, the head water tank, the water storage tank and the membrane reaction vessel are arranged in parallel. The hollow fiber gravity-driven membrane reactor saves a covering area, a soil area and a corresponding infrastructure cost, has a low operation cost and a long service life and is suitable for algae-containing water treatment.

Description

technical field [0001] The invention relates to a membrane reactor and a method for using the same. Background technique [0002] Cyanobacteria blooms in water bodies and the toxic substances produced by cyanobacteria are extremely harmful to humans and animals. Algae blooms will also reduce the economic value of surface water and affect local tourism and the lives of residents. [0003] At present, gravity-driven membrane reactors usually use ultrafiltration membranes and microfiltration membranes, and generally use a water head of 40-100cm as the pressure. Gravity membrane equipment is simple and convenient in design, easy to use, and has a good removal effect on pathogens and suspended particles. At present, most of the gravity-driven membrane reactors use flat membranes. In practical applications, flat membrane reactors have problems such as large footprint and high infrastructure costs; and there are few successful cases of using gravity-driven membrane reactors to tre...
