An in-situ treatment and purification device for polluted rivers

Abstract

The invention discloses an in-situ treatment and purification device for polluted rivers, which belongs to the field of polluted water treatment and comprises a purification mechanism installed under a mounting rod. The microbial oxidation network is arranged between every adjacent two protective back plates. The top of the protective front plate and the protective rear plate are equipped with floating bodies. There are water holes on the left and right sides, and the middle part of the protective back plate is provided with a longitudinal shaft. Mount on pole. The invention can comprehensively control the water body without affecting sailing and flood discharge, can carry out sedimentation and microbial oxidation on the water body, can effectively prevent the growth and reproduction of microorganisms, and ensure the stability of the microbial oxidation function.

Description

technical field [0001] The invention relates to the field of polluted water treatment, in particular to an in-situ treatment and purification device for polluted river courses. Background technique [0002] At present, with the continuous expansion of urban areas, rivers that originally had the function of purification have lost their function, and a large number of urban rivers have evolved into stormwater channels and even sewers. This is a concentrated expression of the lack of urban infrastructure and the imperfection of the pipe network, which eventually causes a large amount of pollution in the urban water body and the surrounding environment deteriorates significantly. [0003] The water flow of urban rivers, in the non-flood period, is mainly polluted by domestic sewage and excrement, which often contain nutrients such as nitrogen and phosphorus, and generally does not contain toxic substances, and belongs to slightly polluted water bodies. In the existing purificat...

Problems solved by technology

In the existing purification technology, a purification system is arranged in the entire width of the river to achieve a certain purification effect, but it is not conducive to the passage of ships and the flood discharge during the flood period. During the flood period, due to the large increase in water flow, the content of nutrients such as nitrogen and phosphorus in the water body The water quality is relatively good. At this time, the river channel should give full play to the function of flood discharge. During the flood period, the water flow increases greatly and there is a risk of destroying the purification system. There are also scattered water purification equipment, but the purification capacity is limited and cannot It can well guarantee the purification effect of micro-polluted water bodies in urban rivers during non-flood periods

The purification system generally includes a sedimentation module, a microbial oxidation module, and an aquatic animal and plant purification module. In the application of the microbial oxidation module, if the water flow rate is fast, the microorganisms are not easy to grow and reproduce, and the grown microorganisms are easily lost by impact, resulting in microbial oxidation.
