Novel double-tower ozone disinfection tower

Abstract

A novel double-tower ozone disinfection tower comprises a main disinfection tower body, an auxiliary disinfection tower body and a water storage tank, the main disinfection tower body is connected with the auxiliary disinfection tower body, and the auxiliary disinfection tower body is connected with the water storage tank; a first packing system is arranged in the main disinfection tower body, andcomprises a primary packing layer, a secondary packing layer, a primary gas distribution device, a secondary gas distribution device, a primary backwashing device, a secondary backwashing device, a primary liquid distribution device and a secondary liquid distribution device; a second packing system and an ultraviolet sterilization device are arranged in the auxiliary disinfection tower body; andthe ultraviolet sterilization device is arranged at the lower side of the second packing system. Compared with like towers in the prior art, the novel double-tower ozone disinfection tower has the advantages of small ozone addition amount in the whole treatment process, fastness in reaction, no secondary pollution, high adaptive capacity, low energy consumption, small occupied area and high treatment efficiency; and the innovative double-tower disinfection arrangement makes the wastewater thoroughly disinfected, so the ecological environment is well protected.

Description

technical field [0001] The patent of the invention belongs to the related field of environmental protection equipment, and specifically relates to a novel double-tower ozone disinfection tower. Background technique [0002] Ozone is an allotrope of oxygen. Unlike ordinary oxygen, it is composed of 3 oxygen atoms and has a molecular formula of O3. It is the strongest known broad-spectrum strong oxidant. The performance of ozone is very unstable, and it will soon be decomposed into O2 and single atom O at room temperature, and two single oxygen atoms O can be combined to form O2. Monatomic oxygen is extremely active, has strong oxidation and decomposition functions, and can quickly kill germs, viruses and other microorganisms. The oxidation ability of ozone is twice as high as that of chlorine, and its bactericidal ability is 600-3000 times faster than that of chlorine, which can kill bacteria and viruses in a few seconds. The method of ozone to deal with bacteria is to dire...

Problems solved by technology

[0004] However, the water quality of sewage is complicated, and there are many factors affecting the water after ozone is added. The waste increases the cost of sewage treatment

At the same time, the solubility of ozone in water is very low. How to fully mix ozone with sewage to quickly kill bacteria is also the difficulty of ozone disinfection in domestic sewage at present.
