Embodiment

[0029] Such as figure 1As shown, the process flow of the water treatment photocatalytic integrated device of the present invention is as follows: the liquid inlet pump 5 connected to the bottom of the organic waste liquid storage tank 3 transports the organic waste water to the pretreatment reaction system 1, and the solid particles in the pretreatment reaction system 1 The water inlet 16 on the upper side of the sedimentation zone 8 enters the reaction system, passes through the sedimentation zone 9 and the buffer zone 10 to slow down the impact of the water flow on the fabric layer, passes through the carbon fiber fabric photocatalytic layer 12, and fixes the carbon fiber fabric layer on the cylinder by the fixing member 21. On the body, the solid particle impurities in this layer of waste liquid are filtered and removed, and the organic matter is adsorbed on the carbon fiber fabric photocatalytic layer, and then enters the photocatalytic reaction zone 11, and there is a laye...

Abstract

The invention discloses an absorption and photocatalysis integrated system for deep-treating organic waste water. A water outlet at the lower end of an organic waste water storage tank is connected into a water inlet at the lower end of a pretreating photocatalysis reaction system by a liquid inlet pump and a flow meter; a water outlet at the upper end of the pretreating photocatalysis reaction system is connected into a water inlet at the lower end of a deep photocatalysis reaction system by a first valve; the water inlet at the lower end of the deep photocatalysis reaction system is connected into a water outlet of another liquid inlet pump by a second valve and another flow meter; a water inlet of another liquid inlet pump is connected into a water outlet at the lower end of a purifiedwater storage tank; and the upper end of the deep photocatalysis reaction system is connected into a water inlet at the upper end of the purified water storage tank. The photocatalysis integrated device has the advantages of double-system water treatment system, simple internal structure, strong shock resistance, reasonable energy utilization and high photocatalytic oxidation efficiency, the establishment of the double-system water treatment system leads the mineralization of organic matters to be more thorough, and the operation is more convenient. The device has easy popularization, industrialization and commercialization.

Description

technical field [0001] The invention relates to a treatment system for organic waste water, in particular to an adsorption and photocatalysis integrated system for advanced treatment of organic waste water. Background technique [0002] Since the last century, the global industry has developed rapidly. The development of industry not only brings rapid changes to human beings, but also poses a huge threat to the environment on which human beings live. Therefore, environmental governance has received widespread attention. Traditional water treatment processes include chemical precipitation, physical separation, electrocoagulation, activated carbon adsorption, and biomass degradation. Large, incomplete removal of organic matter in wastewater and other deficiencies, but subject to certain restrictions. The semiconductor metal oxide photocatalytic oxidation technology is non-selective to the degradation of organic matter in wastewater and can undergo deep reactions to completely...
