PRELIMINARY WASTE SORTING SYSTEM FOR TREATING POLLUTED SEDIMENT OF RIVER AND LAKE MOUTH

摘要

A preliminary waste sorting system for treating polluted river and lake mouth sediment, comprising: a first screening machine (100) and a second screening machine (200), wherein both machines are arranged parallel to each other; a main sediment sludge conveying pipeline (10), wherein one end is connected to a sludge conveying channel of a dredging apparatus; a first sediment sludge conveying branch pipeline (20), one end thereof communicates with the main sediment sludge conveying pipeline (10), and another end thereof communicates with the first screening machine (100); a second sediment sludge conveying branch pipeline (30), one end thereof communicates with the first sediment sludge conveying branch pipeline (20), and a connection between the first and second sediment sludge conveying branch pipelines is positioned at a bottom portion of the first sediment sludge conveying branch pipeline (20), and another end of the second sediment sludge conveying branch pipeline (30) communicates with the second screening machine (200). The preliminary waste sorting system realizes sorting of a construction waste and a domestic waste from a sediment sludge to implement subsequent separation and treatment.
