Aiming at the problem of odorous water and sludge accumulation in river channels,this paper proposes an effective construction technology to treat the black and odorous sludge in the river channel through sieving and impurity removal,sand-water separation,mud-water separation module and combined with the use of PLC+GPRS control system for remote monitoring.In the construction process,the key operation points should be strictly controlled,including pre-construction preparation,site cleaning,foundation bedding and riverbed dredging,equipment assembly and mud entering commissioning,impurity separation,sand separation,mud-water separation,etc.By controlling the mud entering amount to control the sludge treatment rate,determining flocculant dosage,stirring rate parameters to control quality,the goal of maximizing project output and profit can be achieved.
