Embodiment 1

[0026] Embodiments of the present invention are further described below in conjunction with the accompanying drawings:

[0027] The structure of this embodiment is shown as figure 1 shown. Main reactor 100 water inlet is provided with splitter 101, connects bypass O 3 Dosing and mixing integrated module 110 and bypass H 2 o 2 Dosing and mixing integrated module 120, introducing a part of incoming water into bypass O 3 Dosing and mixing integrated module 110 and bypass H 2 o 2 Dosing and mixing integrated module 120. The diverter 101 includes one or more sets of valves and corresponding pipelines, which are used to adjust the water flow in the 110 bypass and 120 bypass. The front end of the main reactor 100 is provided with a H 2 o 2 Pre-mixing module 102, making wastewater with O 3 / H 2 o 2 Before the contact reaction with a small amount of H 2 o 2 well mixed. h 2 o 2 The pre-mixing module 102 is a direct dosing method. h 2 o 2 After the premix module 102 i...

Embodiment 2

[0036] see figure 2 . Embodiment two is the same as embodiment one, the difference is that the main reactor 200 of this embodiment comprises a straight tubular O 3 Pre-mixing module 201, two straight pipe O 3 Dosing module 203, two straight pipe O 3 Mixing module 205, a straight pipe O 3 The reaction module 202 and an elbow-shaped O 3 The reaction module 204 makes the structure more compact. Among them, the straight tube O 3 Module 203 with Bypass O 3 Dosing and mixing integrated modules are connected. The main reactor 200 is equipped with a water inlet pressure gauge 221, an outlet water pressure gauge 222 and an outlet water sampling port 223, which are used to monitor the operation of the equipment in real time and provide data support for reasonable optimization.

[0037] In this example, the typical comprehensive wastewater in the papermaking industry is taken as an example. The conductivity is 8000-12000 μS / cm, the COD is 80-150 mg / L, and the B / C ratio is 0.15-0....

Abstract

The invention discloses a plug flow reactor based on a multiphase oxidation water treatment technology, and a process thereof. The equipment is of a plug flow type reactor structure and comprises a main reactor, an H2O2 premixing module, an H2O2 adding module, an O3 adding module, an O3 mixing module, an O3 / H2O2 reaction module, an O3 adding and mixing integrated module, an H2O2 adding module, anH2O2 mixing module and an H2O2 adding and mixing integrated module. The process is divided into an O3 oxidation mode and an O3-H2O2 oxidation mode, graded and segmented free switching can be achieved,the reaction is promoted through multi-point adding and multiple mixing, organic pollutants difficult to degrade in wastewater are removed, and bromate generation is inhibited. The method has the advantages of high reaction speed, short time, sufficient reaction, low energy consumption, high reaction efficiency, no secondary pollution, simplicity and convenience in operation, small occupied areaand high automation level, wherein the O3 utilization rate reaches more than 90%, and the removal rate of refractory organic pollutants reaches more than 60%.

Description

technical field [0001] The present invention relates to a plug-flow reactor and process based on multiphase oxidation water treatment technology, in particular to a process through O 3 / H 2 o 2 Multi-point dosing and multiple mixing promote the reaction, so as to remove refractory organic pollutants in wastewater with high efficiency and low consumption, and suppress the generation of bromate. The plug-flow reactor and process. Background technique [0002] my country's overall wastewater discharge is increasing year by year, and natural water bodies are deteriorating. pH value, chemical oxygen demand (COD), and ammonia nitrogen are the three major pollutants, and chemical oxygen demand (COD) ranks first. In terms of pollution sources, industrial wastewater pollution is the most serious. According to the "13th Five-Year Plan for National Environmental Protection" officially issued by the Ministry of Environmental Protection, industrial wastewater standard upgrading and a...
