AI Technical Summary

Technical Problem

The traditional dredging method of polluted bottom sludge is inefficient and difficult to achieve precise dredging. The monitoring method is time-consuming and costly, so it is impossible to obtain data in real time, resulting in the inability to effectively deal with the polluted bottom sludge.

Method used

An integrated equipment for quantitative precision dredging and monitoring of polluted bottom sludge was designed, including bottom sludge suction module, bottom sludge identification module, bottom sludge treatment module and in-situ feeding module. The bottom sludge suction module efficiently extracts the bottom sludge from the river bottom through the synergy between the suction tube and the flush tube; the bottom sludge identification module uses a spectrometer to identify the pollution categories of the bottom sludge in real time; the bottom sludge treatment module intelligently allocates and processes according to the identification results; the in-situ addition module adds chemical agents or microbial preparations during the dredging process to promote the degradation or stability of pollutants.

Benefits of technology

The rapid and accurate quantity dredging of polluted bottom sludge has been achieved, reducing dredging time and cost, and improving efficiency; the pollution categories of bottom sludge are identified in real time to provide a scientific basis for subsequent treatment; the resuspension and diffusion of pollutants are reduced through in-situ injection, and secondary pollution to water bodies is avoided.
