The invention relates to the field of remote monitoring systems and discloses a remote monitoring system for a flood control wall. The remote monitoring system comprises a monitoring unit, a fault detection unit, a monitoring alarm unit, a data management unit, an interaction unit and a safety management unit, wherein the monitoring unit is arranged on the flood control wall and used for monitoring the states of the flood control wall, a tide gate, a flap valve and a gate; the fault detection unit is used for detecting whether the monitoring unit works normally or not; the monitoring alarm unit is used for receiving an output signal of the monitoring unit and data output by the fault detection unit; the data management unit is used for receiving monitoring data of the monitoring alarm unitand generating a report with display and printing functions; the interaction unit is connected with an external system through a data communication interface to give an alarm outside; the safety management unit is used for encrypting data output by the data management unit. The system has the advantages and effects as follows: management workers can refer to monitoring data, the whole state of the flood control wall can be more quickly and timely fed back to the superior, and the handling speed of flood situation is increased.

The invention discloses an ecological floating island considering flood control and drainage of urban medium and small river channels and landscape requirements, the ecological floating island comprises a plurality of floating island units which are mutually connected and fixed, and each floating island unit comprises a floating island plate, a planting basket, a curtain type aeration membrane assembly, a microbial filler ball and an aeration pipeline system; buoys are fixed on the periphery of the floating island plate through tension bands; a planting hole is formed in the middle of the floating island plate, a planting basket is embedded in the planting hole, the planting basket is filled with a plant growth substrate, and aquatic plants are planted in the planting basket; a plurality of curtain type aeration membrane assemblies are fixedly mounted at the bottom of the floating island plate; and a microbial filler ball assembly is suspended at the bottom of the floating island plate. The method has the technical effects and advantages that impact pollution caused by urban rainwater runoff to a receiving water body is reduced, and water resources are effectively supplemented. The pollutant purification effect is good, and the removal efficiency of main pollutants in initial rainwater is high. Operation is free of maintenance, power consumption is low, oxygen utilization rate is high, and therefore comprehensive engineering investment is low.
