Description
Technical Field
The invention belongs to the technical field of sewage treatment devices, and particularly relates to an integrated micro-polluted water body treatment device.
Background
With the rapid development of the urban process, a large amount of life and production wastewater containing refractory organic matters of high-concentration medicines and personal care products is discharged into a conventional sewage plant through a municipal pipe network and then is discharged into an aqueous environment after being treated by the sewage plant. However, conventional sewage treatment processes have difficulty in efficiently removing organic pollutants from medicines and personal care products in sewage, thereby causing gradual increase in the types and concentrations of residual refractory organic pollutants in water environments (lake water, river, reservoir water). The residual pollutants in the water environment mainly comprise various antibiotics, environmental estrogens, pesticides and other residual compounds, and the pollutants have long half-life period in the water environment and slow biodegradation, and have potential harm of acute carcinogenesis, deformity and mutation at a certain concentration.
The laboratory scale advanced oxidation technology such as potassium permanganate method, fenton, photo Fenton method, electrocatalytic method and the like has good effect of removing residual refractory organic pollutants, but the laboratory scale equipment has high energy consumption and is not easy to be suitable for purifying large-scale micro-polluted water bodies, such as river and lake V water bodies and water bodies below. At present, most of the conventional municipal engineering treatment methods for the polluted river and lake water body adopt physical methods such as sediment replacement, water body replacement and the like, and the methods have high economic cost and complex operation. Meanwhile, the method does not have the capability of permanently treating the polluted water body, so that development of equipment for continuously treating the polluted water body is needed.
In summary, the current method for treating large-scale polluted water has the following problems: the conventional replacement means has high energy consumption and poor economic benefit; the conventional displacement means cannot continuously treat the polluted water body; biological methods take a long time to treat polluted water bodies.
