Problems solved by technology

[0005] In addition, ozone needs to be produced by high-voltage discharge, which consumes a lot of power.
At the same time, due to the low utilization rate of ozone, in order to ensure the treatment effect, the dosage of ozone in wastewater is relatively high, and ozone tail gas treatment equipment is required behind the ozone oxidation device
Therefore, there are the following problems to be solved urgently in the conventional ozone treatment device and treatment method at present: a. the utilization rate of ozone is low; b. Method investment and operating costs are high

Abstract

The invention provides a deep ozone treatment device and treatment method for organic wastewater biochemical effluent. The deep ozone treatment device for the organic wastewater biochemical effluent is characterized in that a closed ozone oxidizer is included, the top of the ozone oxidizer is connected with a safety valve through a tail gas collection pipeline, an outlet connecting pipeline of the safety valve is connected with an ejector, and the ejector is connected with a water inlet pipeline of the ozone oxidizer. The treatment device is simple in structure and easy to operate, the ozone utilization rate can reach 90% or above by keeping a certain pressure in the ozone oxidizer through a synergistic effect of compound filler, circulating reflux of wastewater and collection and reutilization of ozone, and meanwhile the cost of ozone tail gas treatment equipment is reduced. Accordingly, the device has the advantages of being high in impact resistance and operation stability, good in economy and the like and can be applied to deep treatment on the high-concentration organic wastewater biochemical effluent.

Description

technical field [0001] The invention relates to an organic wastewater biochemical effluent ozone advanced treatment device and a treatment method, which are used for treating high-concentration organic wastewater and belong to the technical field of sewage treatment. Background technique [0002] High-concentration organic wastewater has the characteristics of high pollutant concentration, high chroma, and complex components, such as landfill leachate, papermaking wastewater, printing and dyeing wastewater, etc. After pretreatment and secondary biochemical treatment, the COD value of the effluent is still high, generally It is 200-1000mg / L, the color is usually 100-500 times, and the biodegradability is very low. Therefore, the biochemical effluent of high-concentration organic wastewater needs further advanced treatment before it can be discharged up to the standard. [0003] Ozone has a strong oxidation ability, and its oxidation-reduction potential in water reaches 2.07e...
