Claim 1:
2. The treatment method for a sandy soil landfill solid waste polluted river channel according to claim 1, wherein curing treatment is performed on the ecological concrete, and a method for the curing treatment comprises the following steps:
storing the prepared ecological concrete inside a closed curing cover, uniformly covering the surface of the ecological concrete with a straw curtain, curing for 2 to 5 h at a temperature of 10 to 15° C., adjusting the temperature in the curing cover at a speed of 5 to 7° C./h, injecting wet oxygen with the purity of 99 to 99.99% at a speed of 5 to 10 mL/h in the curing cover until the temperature difference between the temperature in the curing cover and the outdoor temperature is 3 to 5° C., stopping heating, reducing the injection amount of the wet oxygen at a frequency of 0.5 to 1 mL/h, stopping injecting the wet oxygen and withdrawing the concrete out of the curing cover after the humidity of the ecological concrete in the curing cover reaches 70 to 80%, and standing and cooling for later use, wherein the water content of the wet oxygen is 20 to 30%.
