Method for treating high-concentration organic waste water by light cooperated with zinc ferrite activating ozone

Abstract

The invention discloses a method for treating high-concentration organic waste water by light cooperated with zinc ferrite activating ozone, and belongs to the field of a waste water treatment device.Air outlet quantity of nanometer holes and an ozone generator is set to a state that the sum of the pressure of the upper side surface of a sand core distributor and the water pressure generated by the water in the vertical direction thickness of the sand core distributor is smaller than the pressure of the lower side surface of the sand core distributor, so that the ozone uniformly passes through the whole sand core distributor, the flowing uniformity of the ozone from bottom to top can be improved; good combination with water can be realized; the photocatalysis effect is improved. The sandcore distributor provided by the invention can effectively ensure the combination of ozone and water; the uniform combination catalysis with zinc ferrite in water can be realized; the water treatmenteffect is improved; through the sand core distributor, micro bubbles and an ozone oxidization technology are combined; the ozone mass transfer can be enhanced; the ozone utilization rate is improved;the contact of contaminants and ozone is promoted; the effects of degrading the contaminants by ozone oxidization can be obviously improved.

Description

technical field [0001] The invention relates to the field of wastewater treatment devices, and more specifically relates to a device for treating high-concentration organic wastewater with photocooperative zinc ferrite activation and ozone. Background technique [0002] Wastewater refers to the general term for water discharged from residents' activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other useless water such as primary rainwater that flows into drainage pipes and canals. It generally refers to water that cannot be recycled after certain technical treatment or that is difficult to purify after primary pollution and cannot meet a certain standard. [0003] Ozone oxidation is an efficient water treatment technology with almost no secondary pollution. However, the traditional ozone treatment technology has disadvantages such as slow gas-liquid mass transfer rate, low ozone utilization efficiency and low pollutant removal rate. Zi...

Problems solved by technology

However, the traditional ozone treatment technology has disadvantages such as slow gas-liquid mass transfer rate, low ozone utilization efficiency and low pollutant removal rate. Zinc-activated ozone has a good effect in treating wastewater, but at present, the existing decontamination device for treating high-concentration organic wastewater with photocooperative zinc ferrite activated ozone generally has a porous plate inside, and the ozone is dispersed through the porous plate. However, this This method cannot fully combine ozone and water well, and because ozone is not only unstable in water, but will flow out of the water surface after being converted quickly, it is difficult to achieve a better mixing effect, which in turn affects the performance of the catalytic reaction. , most of the current structures are not equipped with dosing devices. For example, sometimes multiple catalysts are required for co-catalysis. For example, adding hydrogen peroxide can effectively improve the treatment effect. Most of these medicines are directly injected after opening the bottle cap, which makes the medicine easy to contact with the air. Some medicines are prone to produce harmful gases when in contact with the air, which not only pollutes the environment, but also is harmful to the human body when they flow into the air. At the same time, the residue filtered out by the existing decontamination device cannot be cleaned well, which brings inconvenience to wastewater treatment.
