Abstract

The invention relates to a device for degrading waste water organic matters by combined type hydraulic power cavitation. The device comprises a Venturi tube component and a sieve mesh plate component which are connected in series and communicated with each other, wherein the water inlet end of the Venturi tube component is connected with a high-pressure pump waste water device; and the water outlet end of the sieve mesh plate component is connected with a water outlet pipeline. According to the device, due to the adoption of the structure, ultra-high pressure and high temperature which are similar to the condition of 'wet air oxidation' are generated and accompanied with strong shock waves and jet flows at the moment of collapsing cavitation bubbles after cavitation by utilizing the hydraulic power cavitation principle, so that part of organic matters in waste water are decomposed into CO2, H2O and inorganic oxides to degrade chemical oxygen demands (COD) and biochemical oxygen demands (BOD). The device is suitable for the pretreatment of the high-concentration organic waste water which is insusceptible to biochemical degradation, and the pH value of the waste water is not limited.

Description

technical field [0001] The invention relates to the field of environmental protection sewage treatment of a device for digesting organic matter in industrial wastewater by hydraulic cavitation technology, in particular to a combined hydraulic cavitation device for degrading organic matter in wastewater. Background technique [0002] The treatment of high-concentration industrial organic wastewater that is difficult to degrade biochemically has been a thorny technical problem for decades, such as chemical industry, medicine, papermaking black liquor, landfill leachate, etc. Therefore, it is also the hottest topic in environmental water treatment. [0003] There are many kinds of catalytic oxidation methods, such as chemical, ultraviolet light, ultrasonic, microwave, ozone and electrocatalytic oxidation. In recent years, there are experimental applications of "wet air oxidation" (WAO) method. These methods are mainly aimed at the treatment of high-concentration refractory bio...
