Embodiment Construction
[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0027] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0028] The present invention provides a multi-stage purification treatment system for treating residual water from polluted sediment in rivers and lakes. The treated residual water meets the discharge standard. At the same time, it can handle...

Provided is a multi-stage purification treatment system for residual water from the treatment of contaminated bottom sludge from a river or lake, the system comprising a primary sedimentation tank (1) for naturally settling and removing particulate matters in the residual water, a secondary sedimentation tank (2) for retaining and removing the particulate matters in the residual water, and a tertiary magnetic filter purification device (3) for adsorbing and removing suspended matters in the residual water, these being sequentially connected in series with one another according to a residual water treatment path, wherein the primary sedimentation tank (1) comprises a first tank body(11); the secondary sedimentation tank (2) comprises a second tank body (21) and a device aiding sedimentation (22); and the tertiary magnetic filter purification device (3) comprises a chemical feeding coagulation device (31) and a magnetic filter device (32) connected with the chemical feeding coagulation device (31). Impurities in the residual water are filtered out and detoxified systematically and step by step, so that the concentration of pollutants in water in river channels can be decreased; and waste water with a higher turbidity can be treated by the system. In addition, the system has a high residual water treatment capacity and a high residual water treatment efficiency, and occupies a small area.
Description
technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a multi-stage purification treatment system for treating residual water from polluted bottom sludge in rivers and lakes. Background technique [0002] The river course is an open water area with a narrow water surface and a long flow. In many places, the river course has become a gathering place for various polluted water bodies. Due to years of deposition, polluted sediment has formed. Polluted sediment is an internal pollution source that affects the quality of water environment. [0003] Environmental dredging is an important means to control heavily polluted water bodies. Through dredging polluted sediment, endogenous pollutants in polluted water bodies can be removed. In traditional dredging projects, since the dredging mud is mainly composed of inorganic particles and has a high density, the natural settlement method can be used to achieve efficient mu...
