Description
Technical Field
The invention belongs to the field of environmental protection, relates to a waste gas and sewage treatment equipment technology, and particularly relates to a stink and sewage treatment system.
Background
With the progress of society and the development of industry, a large amount of waste water and toxic and harmful gas are inevitably generated, and the production environment of human beings is seriously damaged after the waste water and the toxic and harmful gas are discharged into the environment, so that the environmental problems are paid high attention and concern to various countries in the world, and people take various measures to prevent and control the environmental pollution.
The treatment of exhaust gas is currently carried out by water washing (neutral water, acid washing, alkali washing). Generally, the water washing converts the soluble or partially slightly water-soluble substances in the exhaust gas into other substances, such as neutral water (e.g. deionized water) which can convert ammonia gas into ammonia water; the acid washing can convert ammonia, amines and the like into other alkaline substances; alkaline washing is suitable for converting hydrogen sulfide, lower fatty acids, etc. into other acidic substances. Therefore, in order to convert various kinds of malodorous substances in waste gas and wastewater into harmless substances, a multistage chemical washing mode of acid washing and alkali washing in series is generally adopted for deodorization, and an irreversible chemical reaction is generated between the malodorous components and main components of chemical liquid medicine to generate new malodorous substances so as to achieve the aim of deodorization.
At present, the waste gas is handled through the spray column mostly to the washing mode and is realized, and its principle is: and introducing the waste gas into the spray tower to make the waste gas contact with spray water in the spray tower, and treating the waste gas through physical dissolution and chemical reaction. In the actual operation process, after the components in the waste gas are dissolved by the spray water, the chemical reaction efficiency is low, and pollutants cannot be effectively treated. The discharged waste gas and waste liquid also contain untreated pollutants, so that the discharged waste gas and waste water need to be treated again on one hand, and the risk of environmental pollution can be caused on the other hand.
Therefore, there is a need for an improvement of the existing odor and sewage treatment apparatus to solve the above problems.
Disclosure of Invention
The invention aims to solve the problems of low efficiency, high cost and low treatment effect of the existing odor and sewage treatment device for treating odor and/or sewage, and provides an odor and sewage treatment system which has a simple structure, good decomposition effect of pollutant components in odor and/or sewage and low cost.
The design idea of the invention is as follows: cavitation is a physical phenomenon occurring in a liquid medium and refers to the process of formation, development and collapse of vapor or gas cavities within a liquid or at a liquid-solid interface when the local pressure within the liquid is reduced. When cavitation reaction occurs, local extremely high temperature and high pressure are formed at the moment when cavitation bubbles collapse, and strong shock waves and microjets are accompanied, so that strong disturbance and huge shearing force action can be formed in liquid, and simultaneously, impact is formed on an object surface to form a mechanical effect of cavitation; meanwhile, although the collapse time of the cavitation bubbles is extremely short, local hot spots can be formed in tiny spaces around the bubbles during collapse of the cavitation bubbles at the moment of collapse, and a cavitation heat effect can be formed, which can cause decomposition of high molecules of substances, breakage of chemical bonds and generation of free radicals. For example: when the collapse time of the cavitation bubble is in the order of microseconds, the generated high-temperature and high-pressure condition is enough to open O-H bonds (the binding energy is 498.7kJ/mol) in water molecules, so that the water molecules are directly cracked into H and OH free radicals, and the free radicals can further generate HO2And H202. Active radicals having strong oxidizing properties and oxidizing substances are present in a gas phase region inside the cavitation bubbles, an interface layer region near the bubble walls, and a liquid phase region at ambient normal temperature and pressure.
Meanwhile, the ozone catalytic oxidation technology is a process for removing the organic matters which are difficult to biodegrade in the sewage by utilizing the high-reaction-activity free radical intermediate generated on the surface of the catalyst by ozone molecules, particularly hydroxyl free radical oxidation. During the reaction, a large amount of strong oxidative HO radicals can be generated, which can oxidize and decompose organic substances in water to achieve the purpose of purifying water. When dissolved with O3When the sewage (ozone) passes through the filter layer, the catalytic oxidation reaction is carried out under the action of the catalyst, so that the color, turbidity and odor can be effectively removed, and pollutants such as phenol, cyanogen, sulfide, pesticide, petroleum and the like in the sewage can be removed.
Therefore, it is considered that the hydrodynamic cavitation technology can be combined with the ozone catalytic oxidation technology to degrade pollutants in sewage and odor.

According to the invention, by designing the ozone microbubble generating assembly, the ozone microbubble generating assembly can provide ozone microbubbles for the sewage collecting tank in the spray tower, so that the treatment efficiency and effect of water liquid (dissolved with harmful components in odor) in the sewage collecting tank are accelerated.
Furthermore, the first microbubble generator is also communicated with a sewage collecting tank through a second pipeline, and the sewage collecting tank discharges part of water liquid into the first microbubble generator through the second pipeline and mixes the water liquid with ozone to generate ozone microbubbles. The water liquid in the sewage collecting tank circulates between the sewage collecting tank and the first microbubble generator through the second pipeline, so that the utilization rate of the water liquid in the sewage collecting tank is improved, and the water use cost of the system and the subsequent water treatment cost are reduced.
Furthermore, a first ozone catalyst is arranged in the sewage collecting tank and used for catalyzing the decomposition of ozone and generating OH with strong oxidizing property. Specifically, a first ozone catalyst can be placed on the grid, and the first ozone catalyst can efficiently catalyze the conversion of ozone into OH hydroxyl radicals with strong oxidation activity. The ozone microbubbles are in full contact with the first ozone catalyst in the sewage collecting tank and react to generate OH which can oxidize macromolecular harmful substances in water liquid (namely sewage) in the sewage collecting tank and decompose and convert the macromolecular harmful substances into harmless micromolecules so as to achieve the treatment effect.
In a preferred embodiment of the present invention, the odor and sewage treatment system further comprises a hydrodynamic cavitation device, one end of the hydrodynamic cavitation device is communicated with the sewage collecting tank through a third pipeline, and the other end of the hydrodynamic cavitation device is communicated with the spray pipeline in the spray tower through a fourth pipeline. The hydraulic cavitator is used for performing hydraulic cavitation reaction on part of water liquid discharged from the sewage collecting tank and then spraying the water liquid through a spray head of the spray pipeline. The principle of the hydrodynamic cavitation reaction is as follows: when the local pressure in the water liquid is reduced, the formation, development and collapse of steam or gas cavities in the water liquid or on the liquid-solid interface of the water liquid, when the cavitation reaction occurs, local extreme high temperature and high pressure are formed at the moment of collapse of cavitation bubbles, and strong shock waves and micro-jet are accompanied, so that strong disturbance and huge shear force action can be formed in the water liquid, and simultaneously, the impact is formed on the object surface of pollutants in the water liquid to form the mechanical effect of cavitation; although the collapse time of the cavitation bubbles is extremely short, local hot spots are formed in the micro space around the bubbles during collapse of the cavitation bubbles at the moment of collapse, and a cavitation heat effect is formed, which can cause decomposition of high molecules of substances, breakage of chemical bonds and generation of free radicals. In the invention, the hydrodynamic cavitation device can be any device and apparatus which can realize hydrodynamic cavitation principle, including but not limited to jet cavitation device, orifice plate cavitation device, Venturi tube cavitation device, etc.
Furthermore, the hydraulic cavitator is also communicated with an ozone generator through a fifth pipeline, the ozone generator inputs the part for generating ozone into the hydraulic cavitator, and the ozone is mixed with water liquid input into the hydraulic cavitator through a third pipeline, so that the generated liquid vacuoles are ozone vacuoles.
Preferably, the third pipeline is further provided with a pressure gauge, a flow meter and a pressure regulating valve, the pressure gauge and the flow meter can measure the pressure and the flow of the water liquid before cavitation, and then the pressure regulating valve can regulate the pressure of the sewage entering the hydrodynamic cavitation device, so that the hydrodynamic cavitation device can better operate.
Furthermore, the spray head is a hydraulic cavitation spray head, and the hydraulic cavitation spray head is selected, so that the water liquid sprayed out through the spray pipeline can be subjected to further hydraulic cavitation reaction.
Ultraviolet rays are invisible light having a higher frequency than blue-violet light in an electromagnetic spectrum having a wavelength of 400nm to 10nm, and do not cause human vision. When the photon energy of ultraviolet light is greater than the chemical bond energy of organic pollutants, a photolysis reaction is usually generated, so that the chemical bond of the organic pollutants is broken. For example: the photon energy of 185nm ultraviolet rays and 254nm ultraviolet rays is 647kJ/mol and 472kJ/mol respectively, the photon energy is larger than the molecular covalent bond energy of most organic waste gas gases, the covalent bond of most organic waste gas molecules can be directly broken, the molecular chain breakage is caused, and therefore, the macromolecular odor molecules are decomposed into H2O、O2And other small molecules to achieve the odor treatment effect. Meanwhile, when the ultraviolet wavelength is 200nm or less, O is present2The molecule will be decomposed to generate active O; active O and O2Combined to form O3。O3Can produce simple, low-harmful or harmless substances such as H by oxidation reaction with organic pollutant ions in a free state2O、CO2And the like. Irradiating 185nm photons to oxygen molecules to convert oxygen (O)2) After the covalent bond is broken into oxygen atoms, the oxygen atoms are further reacted with the surrounding oxygen molecules (O)2) Combine to form ozone (O) containing 3 oxygen atoms3)。
