Abstract：Inthecontextof "dualcarbon"，takingasewage treatmentplant in Zunyi cityGuizhou provinceasanexample， the sponge transformation plan isanalyzed.Therainwater management inthe factoryarea hasbeen optimized through measures such as permeable paving，grass planting ditches，sunken green spaces，green roofs，storage tanks，rainwater disposalfacilities，andintellgentrainwaterdispatchsystems.Theresultsshowthataftertherenovation，thetotalcontrol rate of rainwater runoff increases to 75% ，the annual reduction of rainwater reaches 28 000m3 ，the concentration of pollutants significantly decreases，the annual rainwater reuse increases to 33 000m3 ，saving 158000kW⋅h of electricity and reducing CO 2 emissions by 11.4t. ，and the environmental and economic benefits are significant.
