Abstract

The invention discloses a tungsten salt composite photocatalytic suspension cascade biomembrane reaction device, and belongs to the technical field of water treatment. A first-stage reactor is arrangebelow the device, No.1 filler is arranged in the primary reactor, a second-stage reactor is arrange above the primary reactor, and No.2 filler is arranged in the secondary reactor; a third-stage reactor is wrapped on the surface of the second-stage reactor; No.3 filler is arranged in the three-stage reactor; a hydraulic valve is arranged at the junction of the first-stage reactor and the second-stage reactor; a sewage storage tank is arranged on the right side of the device and connected with the first-stage reactor through a water delivery pipe, and a water pump is arranged in the water delivery pipe; an aeration head is arranged in the first-stage reactor and connected with the air pump through an air delivery pipe. The tungsten salt composite photocatalysis suspension cascade biomembrane reaction device has excellent treatment effect on slightly polluted water.

Description

technical field [0001] The invention discloses a tungsten salt composite photocatalytic suspension cascade biofilm reaction device, which belongs to the technical field of water treatment. Background technique [0002] The biofilm method refers to a large number of microorganisms (aerobic bacteria, anaerobic bacteria, facultative bacteria, fungi, protozoa and algae, etc.) attached to the surface of the media filter material to form a biofilm. After the sewage is in contact with the biofilm, the biofilm The microorganisms use the organic pollutants in the sewage as nutrients, degrade the organic matter in the metabolic process, and at the same time the microorganisms themselves proliferate to purify the sewage. Among them, the inert carrier that provides the attachment and growth of microorganisms is called filter material or filler. The biofilm method has some unique advantages, such as no need for sludge return, easy operation and management, no sludge bulking problem, eas...
