Problems solved by technology

Because the ozone oxidation speed is relatively slow and has a certain selectivity, it is often used to increase the reaction speed by adding or fixing some catalysts in the reactor. The mixing effect of ozone and catalyst is poor, and "dead angles" often appear in some parts of the reactor, which makes the reaction efficiency low, and the dosage and residual amount of chemicals are large, which affects the subsequent treatment process

specific Embodiment approach 1

[0022] Specific implementation mode one: (see Figure 1-Figure 2) This embodiment consists of a reaction tank 1, a main chemical pipe 2, a vertical chemical dosing pipe 3, a front side main chemical pipe 4, a horizontal chemical dosing pipe 5, an ozone main pipe 6, an ozone horizontal pipe 7, and an ozone aeration branch pipe 8 , outlet pipe 9, water inlet pipe 10, outlet weir 12, upper partition 14, lower partition 15, upper right partition 22; outlet pipe 9 is fixed on the bottom of the left side wall 13 outside of pool 1, outlet weir 12 and left The side walls 13 are arranged in parallel, the outlet weir 12 is arranged on the left side in the pool 1, the lower end of the outlet weir 12 is fixed on the pool floor 18 in the pool 1, the upper right partition 22 is arranged in parallel with the right side wall 16 of the pool 1, the upper right The dividing plate 22 is arranged on the right side in the pool 1, the upper end of the upper right dividing plate 22 is fixed on the po...

specific Embodiment approach 2

[0023] Specific implementation mode two: (see figure 2 ) The difference between this embodiment and the first embodiment is that a valve 11 and a pressure gauge 19 are added between the horizontal medicament dosing pipe 5 and the front side medicament main pipe 4, and one end of the valve 11 is fixed to one end of the pressure gauge 19 Connection, the other end of the valve 11 is fixedly connected with the front medicine dry pipe 4, and the other end of the pressure gauge 19 is fixedly connected with the horizontal medicine dosing pipe 5. Other compositions and connections are the same as in the first embodiment. The increased valve 11 and pressure gauge 19 are used to adjust the dosage.

specific Embodiment approach 3

[0024] Specific implementation mode three: (see figure 1 ) The difference between this embodiment and specific embodiment 1 or 2 is that a valve 11 and a pressure gauge 19 are added between the vertical medicament dosing pipe 3 and the medicament main pipe 2, and one end of the pressure gauge 19 is connected to the vertical medicament dosing pipe. 3. Fixed connection, the other end of the pressure gauge 19 is fixedly connected to one end of the valve 11, and the other end of the valve 11 is fixedly connected to the medicine main pipe 2. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2. The increased valve 11 and pressure gauge 19 are used to adjust the dosage.

Abstract

A micro-porous multi-point adding reactor for water treatment relates a device for improving organic matter efficiency of oxidant oxide water in water treatment. A horizontal medicament adding tube5 is arranged parallelly on the bottom of a water pool, the vertical medicament adding tube3 and the horizontal medicament adding tube5 are arranged vertically in the water pool1, the ozone aerating offtake8 is arranged horizontally on the ozone horizontal tube7, a mico-pore24 is opened on the horizontal medicament reacting tube5 and the vertical medicament adding tube3, the aperture of the micro-pore24 is 0.5mum-0.5mm. It achieves to decrease hydrogen peroxide reacting consumption, improve contact of hydroxy radical and water organic matter, and lower water treating cost.

Description

Technical field: [0001] The invention relates to a device for improving the efficiency of an oxidant in oxidizing organic matter in water in water treatment. Background technique: [0002] With the rapid development of industry, a large amount of refractory pathogenic organic substances are discharged into water bodies, causing water pollution to varying degrees. Due to the increase in population and the shortage of water resources, people have to use this part of the water body, which seriously endangers people's health and industrial and agricultural production. Among them, the water body contains certain toxic substances, "three-caused substances" and endocrine disrupting substances, which have high biological stability. Chinese scientist Jin Qiting once conducted in-depth research on the biological toxicity of these substances, and finally concluded that many of the harmful organic substances are It is difficult to remove by biological methods, and these substances are ...
