Embodiment

[0034] The urban creek treated by the present invention is located in the core area of ​​Sanshui District, Foshan City, Guangdong Province. There are a large number of enterprises within the river basin, the amount of industrial sewage discharged daily is large, the discharge of domestic sewage is large, and the ammonia nitrogen of the river water significantly exceeds the standard. Due to the impact of upstream pollution and various types of sewage in uninterrupted river sections (tributaries), the water body in the basin often falls into the fifth category of water, and the water quality exceeds the standard seriously. stink. The city's rivers are in a relatively serious pollution state. The biological chain of the river water body is broken, and the water body has lost its self-purification and self-repair capabilities. Life and health pose a relatively serious threat, and it also affects the comprehensive management of rivers in the entire Sanshui District.

Abstract

The invention discloses a water quality purification system for an urban river. The river is divided into three treatment areas according to the water quality condition of the urban river, namely an agricultural farming waste water treatment area, a treatment area of branch rivers polluted by waste water from the chemical industry and a domestic waste water treatment area, the water quality purification system for the urban river comprises a sludge cleaning device, biological earthworms, a first biological dam, a second biological dam, a third biological dam and an ecological floating island. According to the water quality purification system and process for the urban river, an integral treatment scheme and a segmented treatment principle are adopted, the river is divided into three segments for segmented treatment, all treatment units are matched reasonably, conditions are created actively for gradually lowering pollution of the river, the ecological system is established artificially, the self-cleaning capacity of the river is gradually restored, all the areas are subjected to targeted treatment according to actual conditions, investment and operating cost are low, and the purifying effect is good. The invention further discloses a water quality purification method for the urban river.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an urban river water purification system and purification method. Background technique [0002] With the advancement of urbanization, the discharge of industrial sewage and domestic sewage is also increasing year by year. Generally, there are many enterprises around rivers in cities, and the pollution of high COD, ammonia nitrogen, sulfide, heavy metals, etc. will not only directly pollute the water body, but also cause Many of these pollutants are biologically toxic and fundamentally destroy the ecological balance of water bodies. Moreover, the domestic sewage of nearby residents is not in place due to the lack of comprehensive domestic sewage pipe network, and domestic pollution will also be discharged into the river, which also seriously affects the self-purification ability of the water body. [0003] Urban rivers are the carrier of urban prosperity and civilized de...
