Water pollution multilayer purification device

Abstract

The invention discloses a water pollution multilayer purification device. The device comprises a first vertical water pipe and a second vertical water pipe, an inclined water pipe is communicated between the first vertical water pipe and the second vertical water pipe, and a circular truncated cone type quicksand groove is formed in the bottom of the inner surface of the inclined water pipe and located on the left side of a sand baffle. The invention relates to the technical field of water pollution treatment. The water pollution multilayer purification device is provided with a sand blockingplate, sand grains or fine solid grains are blocked on the left side of the sand blocking plate; and by arranging a bearing plate, sand grains or fine solid grains are accumulated to reach a certain weight, the bearing plate is pressed downwards to open a sand inlet, the sand grains enter a sand guiding box from the sand inlet to be collected, then the bearing plate returns to the original position under the action of a floating plate to wait for sand accumulation of the next time, and circulation is formed, so the problem that sand or fine solid particles enter in the water pollution purification process is solved, electric power is not needed, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of water pollution treatment, in particular to a water pollution multi-layer 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. [0003] Existing water pollution multi-laye...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a water pollution multi-layer purification device, which solves the problem that the existing water pollution multi-layer devices often use filter screens, and the organic matter or solid particles in the sewage are firstly filtered out through the filter screens. interception, but because the filter screen is made of gaps, smaller sand particles or fine solid particles can still pass through, which will bring troublesome problems to the next step of water purification
