River sediment pollution in-situ deep treatment device and use method thereof

Abstract

The invention discloses a river sediment pollution in-situ advanced treatment device and a use method thereof, the river sediment pollution in-situ advanced treatment device comprises a ship body and a box body used for treating sludge, the surface of the ship body is connected with the top of the box body through a mechanical grabbing arm, and the invention relates to the technical field of river sediment in-situ treatment. According to the in-situ deep treatment device for river sediment pollution and the use method thereof, a deep treatment method of aeration and microbial degradation, namely physical and biological treatment, is adopted, so that the river sediment pollution can be quickly degraded, the water quality of a water body is not influenced, meanwhile, certain dissolved oxygen is provided for the water body, the increase of the number and diversity of microorganisms is promoted, and secondary pollution is avoided; the device can be moved at any time for bottom mud pollution treatment, is particularly suitable for repairing bottom mud of a river containing a monitoring section, prolongs the bacterial liquid degradation time by arranging the S-shaped channel and the return pipe, and is semi-closed, so that the bacterial liquid cannot be quickly lost due to the flow velocity of a water body, the bacterial liquid degradation efficiency is enhanced, and the device is simple to operate, environment-friendly and energy-saving.

Description

technical field [0001] The invention relates to the technical field of in-situ treatment of river bottom mud, in particular to an in-situ advanced treatment device for river bottom mud pollution and a method for using the same. Background technique [0002] With the rapid development of economy and society and the improvement of people's living standards, the amount of pollutants continues to increase. Before interception and collection of sewage, most pollutants converge into rivers, resulting in water pollution. After exogenous pollutants are effectively controlled, endogenous sediment pollution becomes an important source of water pollution. For example, more than 90% of the pollutants in the lake body are accumulated in part of the lake bottom mud. Yang Pan et al. studied the sediment pollution characteristics of the Fei River estuary in Chaohu Hunan Province and found that most of the rivers flow into the lake and estuary confluence bay area, and there are different de...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an in-situ advanced treatment device for river sediment pollution and its use method, which solves the problem that aeration in the water body has little effect on the treatment and repair of the endogenous pollution of the sediment, and directly in the sediment Aeration easily disturbs the sediment and releases the pollutants in the sediment into the water body, causing short-term pollution of the water quality, and the floating of suspended particles increases the turbidity of the water body, which is not conducive to the assessment of the monitoring section. Directly adding microbial agents to the water body costs a lot High, and due to the flow rate of the water body, the microbial agent is easy to lose with the water flow, the microbial degradation of pollutants is slow, and a short stay is required
