Movable contaminated bottom sediment on-site treatment integral device and treatment process thereof

Abstract

The invention relates to a movable contaminated bottom sediment on-site treatment integral device and a treatment process thereof. The integral device comprises a movable assembly and an integral treatment assembly loaded on the movable assembly, wherein the integral treatment assembly comprises a slag-removing sand-removing integral unit, a pre-concentrating unit, a dosing conditioning unit and a deep concentrating and dewatering unit; a slag-removing outlet of the slag-removing and sand-removing integral unit is connected with a sundry collecting device; a sand-removing outlet is connected with a sand grain receiving device; a sewage outlet and a dosing hole of the dosing conditioning unit are connected with the inlet of the pre-concentrating unit together; a bottom sludge outlet of the pre-concentrating unit is connected with the inlet of the deep concentrating and dewatering unit; the bottom outlet of the deep concentrating and dewatering unit is connected with a mud cake receiving device. Compared with the prior art, the movable contaminated bottom sediment on-site treatment integral device and the treatment process thereof have the advantages that contaminated bottom sediment can be treated effectively, and resource utilization of sand grains in the bottom sediment is realized synchronously; meanwhile, the integral treatment assembly is loaded on ta container or a ship in a centralized way, so that the floor area is saved effectively, building cost is lowered, and operation is flexible.

Description

technical field [0001] The invention relates to the field of treatment of river channel polluted bottom mud, in particular to a mobile integrated device for treating polluted bottom mud on site. Background technique [0002] In order to implement the "Water Pollution Prevention and Control Action Plan", the Ministry of Housing and Urban-Rural Development, together with the Ministry of Environmental Protection, the Ministry of Water Resources, and the Ministry of Agriculture, organized the compilation of the "Guidelines for Urban Black and Odor Water Treatment Work" in August 2015 to guide local people's governments at all levels to accelerate the implementation Urban black and odorous water remediation work. River pollution sediment is one of the most important endogenous pollution of black and odorous water bodies. Sediment is an important part of the watershed ecosystem. The buffering capacity of sediment determines the stability of water quality and the stability of algal...
