The present disclosure provides an intelligent low-carbon treatment and reuse system for stormwater and wastewater, including: a bioretention module for collecting stormwater and treating it to obtain treated stormwater; a numerically controlled drainage module for collecting oxidation-reduction potential data and pH data of the treated stormwater and transmitting them to a control module as environmental data, and discharging treated stormwater for a preset time period based on a first control signal sent by the control module; a stormwater and wastewater collection module for storing the discharged treated stormwater and maintaining water storage volume within a preset range; an irrigation module; and the control module. Stable, efficient and low-carbon treatment and reuse of stormwater and wastewater are achieved.

The present invention provides a denitrification and dephosphorization composite filler, a preparation method and application. The composite filler is prepared with a polysulfone polymer as a skeleton and a hybrid denitrification electron donor material by an immersion precipitation phase conversion method. The composite filler designed by the present invention has uniform ball formation and strong controllable performance, solves the problem of poor stability of denitrification and dephosphorization in a system due to the disadvantages of easy system blockage, high consumption speed, weak synergy, etc. in the traditional improved medium, and has broad application prospects in wastewater treatment.
