Problems solved by technology

[0005] The existing technology for resource utilization of the residual sand in the river bottom mud has the following defects: 1) only the residual sand in the bottom mud is separated, and the residual sand of different particle sizes cannot be separated separately to meet the needs of different purposes; Recycling can not maximize the recycling rate of residual sand; 2) The residual sand cannot be cleaned alternately with cleaning solution and water, so that various heavy metals and organic matter cannot be cleaned cleanly, or the residual cleaning solution on the residual sand will affect the utilization effect

Abstract

The invention discloses a multi-stage separation resource treatment system for residual sand of river bottom mud, which belongs to the technical field of water conservancy engineering. Through the setting of screens with different meshes on the multi-stage sorting drum, the residual sand with different particle sizes is separated to improve the sorting effect, and then the residual sand with different particle sizes is cleaned by using the washing element, and the residual sand with different particle sizes is cleaned by drying The dry element dries the residual sand of different particle sizes separately to meet the resource utilization of residual sand of different particle sizes, maximize its utilization rate, and meet the characteristics of energy saving and environmental protection; multiple cleaning chambers are used for multiple cleaning of residual sand Repeated stirring and cleaning can fully remove various heavy metals, organic matter, etc. in the residual sand, and improve the flushing effect and resource utilization of the residual sand; the process of the present invention can maximize the utilization rate of the residual sand, and has excellent separation effect, The advantages of thorough cleaning, energy saving and environmental protection are suitable for mass promotion.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to a multi-stage separation resource processing system for river bottom mud and residual sand. Background technique [0002] In recent years, the problem of river pollution has become more and more prominent in the process of urban development. It not only seriously restricts the sustainable development of economy and society, but also seriously threatens the survival of human beings. It is a great challenge to the current construction of urban ecological civilization. In the past 30 years, a lot of energy has been devoted to the treatment of river black and odorous sediment at home and abroad, and a lot of research work has been carried out. As one of the key technologies in the sediment treatment operation, the sediment separation technology is harmless to the sediment output. Treatment and resource utilization play a vital role. [0003] As one ...
