Background
At present, the annual clearing and transporting amount of domestic garbage in China reaches two to three hundred million tons, and one hundred million tons of domestic garbage are disposed by an incineration method. The garbage disposal byproduct, namely leachate, which has great harm to the environment is generated in the garbage stacking process. In order to reduce the potential risk of the discharge of the garbage percolate to the whole environment, China requires that matched in-situ percolate treatment equipment is built in an incineration plant or a landfill site so as to ensure that the discharge of the percolate reaches the standard for controlling the pollution of the incineration of the household garbage (GB 18485-2014) and the standard for controlling the pollutants of the landfill site of the household garbage (GB 16889-2008). Since landfill leachate contains high pollutants difficult to biodegrade, the corresponding pollution control requirements are difficult to achieve by adopting conventional biochemical treatment and chemical treatment technologies, and under the background, membrane treatment is widely applied as a physical treatment technology with low operation cost.
However, the membrane treatment can produce concentrated liquor which is 20-30% of the volume of the percolate, the concentrated liquor of the membrane filtration is rich in various pollutants in the percolate before the membrane filtration, the humus and the salt content of the concentrated liquor are high, and the further treatment difficulty is high. At present, most of membrane filtration concentrated solutions of landfill sites are treated by methods such as evaporation concentration and the like, most of membrane filtration concentrated solutions of incineration plants are sprayed back to an incinerator, the treatment cost is very high, and according to estimation in the industry, each ton of membrane filtration concentrated solutions to be treated at least needs to consume heat equivalent to 600 degrees of electricity. Therefore, how to reduce the cost of the membrane filtration concentrate of the landfill leachate becomes an industrial hotspot problem. The advanced oxidation method has attracted attention as a technique that can improve the biochemical property of refractory wastewater and create conditions for the concentrated solution to flow back to a front end biochemical system after being treated.
The ozone oxidation technology has strong oxidation capability, not only has good effect on organic matters and inorganic matters, but also has the functions of deodorization, disinfection, sterilization and the like, and is applied to the treatment of percolate to a certain degree as a green and friendly technology. Patent document CN206570116U discloses a treatment device for multistage catalytic ozonation for advanced treatment, in which ozone is catalyzed by a catalyst to improve the utilization efficiency of ozone, thereby further improving the degradation effect. Patent document CN201910554317.2 discloses a method for treating leachate with calcium peroxide in combination with ozone to improve the utilization efficiency of ozone. However, the above methods all need to introduce new reagents, and at the same time, 85% -90% of oxygen is mixed in the reaction device during the ozone reaction, which means that the problem of large oxygen consumption of the ozone system still cannot be solved.
Therefore, it is very important to construct a cooperative ozone integrated device which is mainly used for synchronously improving the utilization rate of oxygen and ozone in the field of landfill leachate treatment.
