the method comprises the following steps: preparing required materials, wherein the materials comprise 30% hydrogen peroxide solution, 10% H2SO4 solution, 30% NaOH, FeSO 4.7H 2O, CuSO4, activated carbon, PAC, PAM and landfill leachate water samples;

step two: preparing required instruments, namely a pH meter, an aerator, a magnetic stirrer, a spectrophotometer, a turbidimeter and an ORP meter;

step three: the working process comprises the steps of putting a certain amount of water sample into a fixed container, adjusting the pH value to 3.5 by using a 10% H2SO4 solution, adding a 30% hydrogen peroxide solution, FeSO 4.7H 2O and CuSO4 at one time, starting an oxygenator, uniformly aerating for 2 hours, keeping the ORP more than 600mv in the experimental process, adding three thousandth of PAC solution, quickly stirring for 6 minutes, slowly stirring for 3 minutes by using one thousandth of PAM solution, adding a 30% NaOH solution, adjusting the pH value to 9.5, standing the solution for 2 hours, taking supernate, adding activated carbon, uniformly stirring, and filtering by using filter paper at medium speed to obtain target effluent;

step four: the garbage leachate enters a sedimentation tank to adjust the water quality and water quantity, then enters a pretreatment system to be pretreated, and is subjected to coagulation process inside the sedimentation tank, wherein the coagulation process is the most basic and important treatment process in the treatment of industrial water and domestic sewage. The flocculating constituent has strong adsorption capacity, can adsorb suspended matters, and can adsorb partial bacteria and soluble substances. The flocculating constituent sinks through adsorption and volume increase, so that partial organic matters are removed, the chromaticity is reduced, the Fenton operation load is reduced, the content of suspended matters, metal ions and coarse suspended matters in the landfill leachate are removed, and after the sedimentation treatment is finished in the sedimentation tank, the effluent enters an aeration tank through a connecting pipe to be subjected to aeration treatment;

step five: the water after the aeration enters the inside of the filter box, is adsorbed by an activated carbon plate in the filter box and is finally discharged for use, and the activated carbon adsorption is a purifying agent with the best organic wastewater and odor treatment effect. Activated carbon adsorption is an effective measure to remove water odor, natural and synthetic dissolved organic matter, micro-pollutants, etc.
