Novel efficient ozone disinfection tower for wastewater treatment

Abstract

A novel efficient ozone disinfection tower for wastewater treatment comprises a tower body, a water storage tank and a packing system; the packing system comprises a first-stage packing layer, a second-stage packing layer, a first-stage gas distribution device, a second-stage gas distribution device, a first-stage backwashing device, a second-stage backwashing device, a first-stage liquid distribution device and a second-stage liquid distribution device; and a first packing bracket is arranged in the tower body, the first-stage packing layer is placed on the first packing bracket, the first-stage gas distribution device is arranged below the first packing bracket, the first-stage backwashing device is arranged above the first packing bracket, and the first-stage liquid distribution deviceis arranged above the first-stage packing layer. Wastewater is disinfected under the action of a strong oxidant ozone to achieve pretreatment or advanced treatment, a liquid flows into the water storage tank, and gas is discharged from a rain-proof cap, so compared with disinfection towers in the prior art, the novel efficient ozone disinfection tower has the advantages of small ozone addition amount in the whole treatment process, quick reaction, no secondary pollution, strong adaptability, low energy consumption, small occupied area and high treatment efficiency.

Description

technical field [0001] The patent of the present invention belongs to the related field of environmental protection equipment, and specifically relates to a new high-efficiency ozone disinfection tower for wastewater treatment. 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 ozon...

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.
