It should be noted that the ozone generator 12, the oxidation tower, the MABR reactor 8 and the tail gas destruction unit 13 adopted in the present invention are all prior art, and therefore, the working principle thereof is easily determined by those skilled in the art, and the present invention is not described herein in detail.
In some embodiments of the invention, the diameter of the bubbles is 1 μm or more and less than 1 mm.
In some embodiments of the invention, the water outlet of the oxidation tower is higher than the water inlet of the oxidation tower.
In some embodiments of the invention, the water outlet of the MABR reactor 8 is higher than the return water inlet of the MABR reactor 8.
In some embodiments of the present invention, the outlet tank 10 is further provided with a water outlet, and an on-line chemical oxygen demand tester (not shown) is installed on the water outlet for detecting the COD value of the body of water flowing out from the water outlet of the outlet tank 10.
In some embodiments of the invention, an ozone concentration detector (not shown) is also provided in the conduit between the outlet of the exhaust gas destruction device 13 and the inlet of the MABR reactor 8, for detecting the concentration of ozone in the gas exiting the outlet of the exhaust gas destruction device 13.
In some embodiments of the present invention, the output end of the water inlet tank 1 is further provided with a second flow pump 2 to detect the flow of black odorous water input to the oxidation tower in real time and control the flow of black odorous water entering the oxidation tower.
In some embodiments of the present invention, a first flow pump 2 is further disposed on the pipeline between the outlet of the ozone generator 12 and the micro-interface generator 7 for controlling and detecting the flow rate of the ozone gas entering the oxidation tower, so as to optimize the catalytic oxidation reaction effect of the ozone in the oxidation tower. Specifically, the ozone generator 12 decomposes and polymerizes a part of oxygen in the air into ozone by high-voltage ionization or chemical or photochemical reaction.
The present invention further comprises a controller 16, wherein the controller 16 receives the ozone flow Q1 of the first flow pump 2 and the black and odorous water flow Q2 of the second flow pump 11, respectively, and a pressure detecting element, such as a sensor, is further disposed in the oxidation tower for detecting the pressure value P1 of the oxidation tower in real time. The micro-interface generator 7 of the embodiment controls the gas-liquid ratio by controlling the pressure P in the micro-interface generator, and further controls the reaction efficiency of the micro-interface generator 7. A reference pressure P0, an ozone reference flow rate Q10 and a black odorous water reference flow rate Q20 in the micro interface generator 7 are set, the ozone reference flow rate is determined by comparing a real-time pressure value P in the micro interface generator 7 with the reference pressure P0, and the ozone flow rate Q1 detected in real time is made to coincide with the ozone reference flow rate Q10 by adjusting the first flow pump 2.
Specifically, the embodiment of the present invention can adjust the reaction efficiency of the micro-interface generator 7 according to the different reaction degree of the black odorous water, for example, at the initial stage of the reaction between the black odorous water and the ozone, the pressure value of the oxidation tower should be increased appropriately so as to better fuse the black odorous water and the ozone, and the reaction system of the oxidation tower itself is combined with the reaction system of the micro-interface generator. The pressure value in the oxidation tower is determined by the ozone flow rate and the black odorous water flow rate, and when the ozone flow rate is high, the pressure value in the oxidation tower is high, so the ozone reference flow rate Q10 is set at the initial stage of the reaction, the ratio of the black odorous water reference flow rate Q20 is a1, the ozone reference flow rate Q10 is set at the middle stage of the reaction, the ratio of the black odorous water reference flow rate Q20 is a2, a1> a2 is set, and a1 and a2 are predetermined.
Specifically, in the case where the gas-liquid ratio is large in a controllable range, the micro-interface generator 7 of the present embodiment enhances the interface reaction between the ozone gas and the black odorous water, reduces the bubble particle size, increases the contact area, and increases the efficiency of the reaction system even in the early stage of the reaction.
Specifically, since the reaction efficiency of the micro-interface generator 7 of the present embodiment has an appropriate relationship with the liquid density and is related to the liquid volume flow rate in the reactor, the setting of the black odorous water reference flow rate Q20 depends on the cross-sectional area of the micro-interface generator 7 and the pressure therein. The above calculations may be calculated by a computational model.
In some embodiments of the present invention, a filtering structure is further disposed between the black odorous water and the oxidation tower, and may be a filter or filter cotton, and preferably, the black odorous water is subjected to secondary filtration to remove large-particle impurities and impurities therein.
In some embodiments of the invention, the exhaust control destruction device 13 comprises a heated ozone exhaust destruction device, a catalytic decomposition ozone exhaust destruction device, and an adsorption ozone exhaust destruction device.
In some embodiments of the present invention, the system may further comprise two oxidation towers in series, a first oxidation tower 3 and a second oxidation tower 4; the water outlet of the water inlet tank 1 is connected with the water inlet of the first oxidation tower 3 through a pipeline, the water outlet of the first oxidation tower 3 is communicated with the water inlet of the second oxidation tower 4, and the water outlet of the second oxidation tower 4 is communicated with the water inlet of the MABR reactor 8.
The invention also provides a control method of the black odorous water of the intelligent black odorous water control system, wherein the black odorous water enters the oxidation tower, ozone gas in the ozone reactor 12 enters the oxidation tower through the micro-interface generator 7 to form gas-liquid emulsion with the black odorous water, the gas-liquid emulsion reacts in the oxidation tower under the action of the catalyst 5, and reaction products enter the MABR reactor 8.
In the MABR reactor 8, black odorous water is in contact reaction with the membrane module 9 inside the MABR reactor 8 for further degradation. The micro-interface generator 7 is used to break up the gas from the ozone generator 12 into said bubbles, thereby increasing the gas-liquid interfacial area.
Referring to fig. 2, which is a functional block diagram of an intelligent control system for black and odorous water according to the present invention, the controller is connected to an artificial intelligence module, and the artificial intelligence module corrects each reference parameter by combining each detection control element of black and odorous water with big data, so as to set the reference pressure P0, the ozone reference flow Q10, and the black and odorous water reference flow Q20 of the micro-interface generator in real time in an intelligent manner.
