River water circulation and water purification combined system and purification method thereof

Abstract

The invention provides a river water circulation and water purification combined system and a purification method thereof. The system comprises a lifting pump station, which is arranged on the lower stream of a river and is used to lift the water from lower stream to the upper stream; a water processing unit, which is arranged in the middle stream and is used to process the water; and at least one wetland ecological purification area, which is arranged on the upper stream and is used to purify the water. The purification method comprises the following steps: (1) lifting the river water from the lower stream to the middle and upper stream of a river through the lifting pump station; (2) introducing the river water into the water processing unit arranged in the middle stream of the river, and directly discharging the processed river water into the river or the wetland ecological purification area; (3) lifting the river water, which has been purified by the water processing unit, to the wetland ecological purification area to carry out a wetland biological treatment; (4) returning the river water, which has been processed in the wetland biological purification area, to the river to complete internal circulation. The shortages of single technology are overcome, the river water quality is continuously improved, and the ecological function and landscape of the river are improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a combined system of river water circulation and water quality purification and a purification method thereof. Background technique [0002] More than 90% of my country's urban water pollution is serious, and frequent water pollution incidents in various places have seriously affected people's daily production and life. The government has invested a lot of money in the construction of sewage collection pipe networks and sewage treatment plants, and the renovation of rain and sewage diversion in old urban areas. However, urban water pollution has not improved significantly. With the large-scale advancement of urbanization, pollution is still increasing. possible. After the urban sewage purification treatment is basically completed, poor water circulation and poor self-purification capacity of urban rivers are the main reasons for the deterioration of urban water environm...

AI Technical Summary

Problems solved by technology

River replenishment can increase river water flow and promote river water circulation, but it cannot fundamentally solve the problem of river water environment deterioration; sediment dredging and chemical restoration methods are effective but cannot restore river water ecosystems; biological and ecological restoration technologies combine microorganisms, Restoration measures such as algae, plants, and ecology can be combined to play a role in an organic way, which can continuously improve the water quality of the river and continuously repair the damaged ecosystem of the river. This method takes a long time; The river water purification method has been developed, but the treatment effect is not good
