Embodiment 1

[0026] Take the ecological purification project of drinking water sources in a city that treats slightly polluted river water as an example. The main purpose of the project construction is to treat slightly polluted water sources in urban river-type water sources, improve urban water supply sources, and ensure that the water quality of wetlands after purification is stable and reaches Class III water. Standard, meeting the recent 300,000 m of urban water plants 3 / d scale of water supply. At the same time, making full use of the water storage capacity of the project, in the event of an unexpected environmental incident, it can quickly cut off the source of pollution, ensure 7 days of normal water supply, and ensure the safety of water supply in the water plant. The project covers a total area of ​​3,350 mu. The main project is divided into five treatment units: inlet canal, ecological storage pond, surface flow constructed wetland, horizontal subsurface flow constructed wetlan...

Abstract

The invention discloses a micro-polluted water ecological purification system suitable for a river water source. The micro-polluted water ecological purification system is formed by connecting a waterinlet channel, an ecological water storage pond, a surface flow constructed wetland, a horizontal underflow constructed wetland and an ecological oxidation pond in series, wherein the water outlet ofthe water inlet channel is provided with a drop weir communicated with the ecological water storage pond, the water outlet of the ecological water storage pond is provided with a water distribution channel communicated with the surface flow constructed wetland, the ecological water storage pond is communicated with the water distribution channel through a water collection pipe, the surface flow constructed wetland is communicated with the horizontal subsurface flow constructed wetland through a water collection pipe, a tumbling dam is arranged at the outlet of the horizontal subsurface flow constructed wetland and is communicated with the ecological oxidation pond, a carbon source adding area is arranged in the horizontal subsurface flow constructed wetland, and the water outlet of the ecological oxidation pond is communicated with a water supply plant. A biological purification technology is adopted, and a continuous aerobic-anaerobic process is set according to the pollutant conversion rule, so the system has a good purification effect on water, and also has good landscape values and good economic benefits.

Description

technical field [0001] The invention belongs to the field of water purification, and in particular relates to an ecological purification system for slightly polluted water bodies suitable for river-type water sources. Background technique [0002] Drinking water safety is related to the life and health of the people and the harmony and stability of social development, and is an important material basis for the sustainable development of human society. As one of the main water supply sources for human life, river-type water sources have been in an open and complex environment for a long time, and their water quality is poor and unstable. Therefore, improving the quality of drinking water in river-type water sources and ensuring the safety of drinking water for residents has become an important issue. It is a key problem that urgently needs to be solved for the sustainable development of our country's society. [0003] Slightly polluted river water refers to the water body po...
