Description

TECHNICAL FIELD

[0001] The utility model relates to water treatment technical field especially relates to a water treatment system based on ozone catalytic oxidation. BACKGROUND

[0002] In recent years, water pollution has become a global environmental problem. Pesticides, health care products and endocrine disruptors and other organic molecules are often detected in water resources around the world and have been proven to have potential harm to human health and even the entire ecosystem. These highly stable organic pollutants have low concentration, are not easy to degrade, are highly toxic and have strong persistence in water. Removal of these pollutants is often affected by different factors in complex environments, especially coexisting substances such as natural organic matter. Most current water treatment processes cannot effectively remove such pollutants, which is a challenge to the field of water treatment.

[0003] Among them, ozone catalytic oxidation is the most widely used water pollution advanced treatment technology. Ozone is a strong oxidizing agent with an oxidation-reduction potential of 2.07eV, and its oxidation ability is higher than that of potassium permanganate, chlorine dioxide, hydrogen peroxide and oxygen. At the same time, the ozone reaction in the product is oxygen, which will not cause secondary pollution. Generally speaking, ozone and organic matter in water mainly react through two ways: direct reaction and indirect reaction. Direct reaction is the direct reaction of ozone molecules with organic matter, and indirect reaction is that ozone is first decomposed in water to produce strong oxidizing free radicals (mainly -OH), and then the free radicals react with organic matter. Generally, the direct reaction of ozone and organic matter has strong selectivity and is more likely to attack organic matter with double bonds. Since -OH has strong oxidizing properties and reacts rapidly with organic matter, a series of advanced oxidation technologies aimed at promoting the decomposition of ozone to produce -OH have been developed based on ozone oxidation.

[0004] The biggest feature of ozone catalytic oxidation technology is to remove organic matter in water that is not easy to degrade and has strong stability, and it has good effect on oxidizing and decomposing many macromolecular organic matter into small molecular substances that are easily utilized by microorganisms, and is easy to use.

[0005] In the process of realizing the utility model, the inventors found that at least the following problems exist in the prior art:

[0006] Ozone catalytic oxidation technology mainly degrades organic matter in water that is not easy to be degraded by microorganisms and removes toxicity in water. The main degradation indicators are COD and color in water, and there is no degradation effect on ammonia nitrogen in water. On the contrary, organic nitrogen in organic matter in water after ozone catalytic oxidation will be converted into ammonia nitrogen, resulting in an increase in ammonia nitrogen in ozone effluent. Therefore, many ozone catalytic oxidation processes on the market will be matched with a biochemical treatment unit. However, in actual application, the ozone concentration in ozone catalytic oxidation effluent is too high, which affects the activity of microorganisms in the subsequent biochemical treatment unit.

[0007] Therefore, there is a need for an ozone catalytic oxidation-based water treatment system to at least partially solve the above technical problems. Utility model content

[0069] A second conveying pipeline 172 for communicating to the biochemical treatment unit 190 has one end communicating to the ozone releasing buffer tank 150, used to guide the raw water in the ozone releasing buffer tank 150, which has been driven out of ozone.

[0070] According to the foregoing, the water treatment system 100 according to the present application further includes a second ozone concentration instrument 182 arranged in the second conveying pipeline 172, used to sense the ozone concentration in the raw water driven out of ozone flowing through the second conveying pipeline 172.

[0073] In order to provide a simple and effective ozone removal device 160, the ozone removal device 160 can be an air stripping device. It can be understood that the use of the air stripping device by the ozone removal device 160 is not limited.

The cyclone aerator 162 is connected to the air blower 161 via a pipeline for filling air into the ozone release buffer tank 150.

[0076] Continuing to refer to Figure 1 In the preferred embodiment, in order to realize automatic control, the water treatment system 100 according to the utility model can further include a control device 200. The control device 200 adopts existing technical equipment, for example, can be PLC, DCS, single-chip microcomputer or industrial computer, etc., and the specific type is not limited.

[0077] Specifically, the control device 200 can be signal connected to the ozone generator 120 and the first ozone concentration instrument 141 respectively, or the control device 200 can be signal connected to the ozone removal device 160 and the first ozone concentration instrument 141 respectively, or the control device 200 can be signal connected to the ozone removal device 160 and the second ozone concentration instrument 182 respectively, or the control device 200 can be signal connected to the ozone generator 120, the ozone removal device 160, the first ozone concentration instrument 141 and the second ozone concentration instrument 182 respectively.

[0078] When the control device 200 is signal connected to the ozone generator 120 and the first ozone concentration instrument 141 respectively, the control device 200 controls the ozone generator 120 according to the ozone concentration sensed by the first ozone concentration instrument 141, so as to control the ozone generator 120 to reduce to the set ozone dosage when the ozone concentration exceeds the first threshold value, so as to realize the reduction of the ozone gas added.

[0079] When the control device 200 is signal connected to the ozone removal device 160 and the first ozone concentration instrument 141 respectively, the control device 200 controls the ozone removal device 160 according to the ozone concentration sensed by the first ozone concentration instrument 141, so as to start the ozone removal device 160 when the ozone concentration exceeds the first threshold value, so as to realize the start of the ozone removal.

[0080] When the control device 200 is signal connected to the ozone removal device 160 and the second ozone concentration instrument 182 respectively, the control device 200 controls the ozone removal device 160 according to the ozone concentration sensed by the second ozone concentration instrument 182, so as to close the ozone removal device 160 when the ozone concentration is lower than the second threshold value, so as to realize the stop of the ozone removal.

[0081] Taking the air stripping device as an example, the control device 200 controls the ozone generator 120 and the air stripping device through the feedforward of the first ozone concentration instrument 141, and controls the air stripping device through the feedback of the second ozone concentration instrument 182. When the ozone concentration of the effluent of the ozone catalytic oxidation tank 110 is too high (exceeding the first threshold value), the ozone generator 120 is reduced to the set ozone dosage, the ozone dosage is reduced, and the air stripping device of the ozone release buffer tank 150 is started; when the ozone concentration on the water inlet pipeline of the biochemical treatment unit 190 is reduced to the allowable range (lower than the second threshold value), the air stripping device stops running.

[0082] It can be understood that the control device 200 can also control the light decomposition ozone device, the activated carbon feeding device, the thermal decomposition device, the electromagnetic radiation device or the chemical liquid feeding device mentioned in the foregoing to realize the switching between the working and the shutdown.
