Embodiment
[0032] According to the invention Figure 1-2 It can be seen from the process flow diagram that the combined ozone system of the present invention includes a raw water tank 1, a first coagulation tank 2, a first sedimentation tank 3, a second coagulation tank 4, a second sedimentation tank 5, an intermediate Pool (intermediate pool) 6 and multistage ozone advanced oxidation device and biological activated carbon device; Described multistage is at least two ends, and each stage ozone advanced oxidation device 7 and biological activated carbon device 8 are alternately connected. With the above structure, by setting a multi-stage AOP device + BAC device, compared with the one-stage type, the amount of catalyst used can be greatly reduced, and the processing efficiency of the BAC tower can be improved. Reduce operating costs. As shown in the drawings, this embodiment adopts advanced ozone oxidation devices and biological activated carbon devices at both ends, and a water outlet p...

The invention discloses an ozone combined system and a method for treating ultrafiltration produced water or a membrane concentrated solution with the same. The system comprises a raw water tank, a first coagulating basin, a fist sedimentation basin, a second coagulating basin, a second sedimentation basin, an intermediate water tank, multiple sections of ozone advanced oxidation devices and a biological activated carbon device which are connected sequentially, wherein at least two sections of ozone advanced oxidation devices are included, and the multiple sections of ozone advanced oxidationdevices are alternately connected with the biological activated carbon device. Compared with the prior art, the treatment method and process have the following advantages: 1) no concentrated solutionis produced; 2) the system can operate continuously for a long time; 3) equipment is simple; 4) maintenance cost is low; 5) operation is simple; 6) compared with one section, multiple sections of AOPtowers and BAC towers are arranged, so that catalyst dose can be reduced greatly, treatment efficiency of the BAC towers can be increased, and operation cost can be reduced.
Description
technical field [0001] The invention relates to the field of advanced treatment of landfill leachate and industrial waste water, in particular to an ozone combination system and a method for treating ultrafiltration water or membrane concentrate by using the same. Background technique [0002] Landfill leachate or industrial wastewater membrane concentrate has the characteristics of high pollutant concentration, complex composition, and difficult treatment. At present, domestic landfill leachate or industrial wastewater treatment processes are mostly a combination of physical treatment and biochemical treatment. The general process is "pretreatment + biological treatment + membrane treatment". Ultrafiltration and nanofiltration are commonly used for membrane treatment. , reverse osmosis or a combination thereof. [0003] Membrane treatment technology has the advantages of good effluent quality, safety and reliability, and simple operation. However, membrane treatment techno...
