Abstract

The invention relates to a suction sludge dewatering sand dredger which is characterized in that a sludge processing device is arranged on a boat body and comprises an extracting unit, a sieving unit, a heavy metal processing unit, a dewatering unit, a deodorizing unit, a dewatered sludge collecting unit and a wastewater processing and discharging unit. In the invention, the integral design of sediment dewatering processing device for urban landscape water pollution is realized; the sludge is immediately dried and dewatered while dredging; and the processed sludge can be directly used in the agricultural field, therefore, the pollution on the environment is avoided.

Description

technical field [0001] The invention belongs to a dredging ship, in particular to a cutter suction type sludge dewatering dredging ship. Background technique [0002] With the development of society and economy, the water quality deterioration of landscape water bodies in cities and suburbs in my country is becoming more and more serious. In order to improve the water pollution status and control the internal source pollution of landscape water, sediment dredging, as a thorough treatment method in the treatment and restoration of polluted landscape water, is increasingly being used in landscape water treatment projects. According to incomplete statistics, from 1998 to 2005 alone, 40 lakes were dredged for environmental protection, involving more than 20 cities, and about 37.583 million m of sediment was dredged out of the lake 3 . The sediment is mainly composed of organic matter and contains a large amount of harmful substances such as pathogenic bacteria, viruses, and pa...
