Water pollution filtering and purifying device

Abstract

The invention discloses a water pollution filtering and purifying device, and belongs to the field of sewage purifying. The water pollution filtering and purifying device comprises a water inlet pipeand a coarse filtering tank, a fine filtering tank, a settling tank, a microorganism purifying tank, a disinfection tank, an aeration tank, a membrane tank and a water outlet pipe which are sequentially communicated; the other end of the water outlet pipe is connected with a pure water inlet of a centrifugal filtering device, the centrifugal filtering device comprises a water purifying device, anda pure water outlet is formed in the bottom end of the water purifying device; a purifying layer comprises a non-woven fabric layer, an agent particle layer and an immobilized microorganism layer from outside to inside in sequence, and a fixing skeleton is connected with the middle of the purifying layer in an inserted mode. Sewage is subjected to a series of sewage treatment processes, so that comprehensive purifying treatment of the sewage is achieved, and the sewage purifying degree is improved.

Description

technical field [0001] The invention relates to the field of sewage purification, more specifically, to a water pollution filtering and purification device. Background technique [0002] Water pollution is water that reduces or loses the use value of water caused by harmful chemicals and pollutes the environment. Acids, alkalis, oxidants, and compounds such as copper, cadmium, mercury, and arsenic in sewage, organic poisons such as benzene, dichloroethane, and ethylene glycol, will kill aquatic organisms and affect drinking water sources and scenic spots. When the organic matter in the sewage is decomposed by microorganisms, the oxygen in the water is consumed, which affects the life of aquatic organisms. After the dissolved oxygen in the water is exhausted, the organic matter undergoes anaerobic decomposition, producing hydrogen sulfide, mercaptan and other unpleasant gases, which further deteriorates the water quality. Contents of the invention [0003] In order to solv...
