Riverway flood discharge and treatment system

Abstract

The invention discloses a riverway flood discharge and treatment system, which comprises a plurality of flood discharge dams arranged in a riverway, a water outlet is formed in the bottom of one sideof the first flood discharge dam, a dosing area, a settling area and a water purification area are sequentially arranged on the downstream of the water outlet, a slow flow structure connected with thewater outlet of the flood discharge dam is arranged in the dosing area, and a mud scraper is arranged in the settling area. The mud scraper is connected with a driving system arranged on a river bank, and a water purification device is arranged in the water purification area. The system is simple in structure, low in cost, high in pertinence, high in efficiency and good in effect, segmentation and timely treatment of a river channel can be effectively achieved, and the river channel treatment work amount and treatment difficulty are greatly reduced; the multiple flood discharge dams are arranged and used for guaranteeing normal operation of the water treatment system, the flow speed and flow of the riverway can be guaranteed, safety around the riverway is guaranteed, and practicability ishigh.

Description

technical field [0001] The invention relates to the field of river water treatment, in particular to a river flood discharge and treatment system. Background technique [0002] At present, with the advent of the rainy season, rainwater, road drainage systems, various domestic sewage and industrial sewage, etc. are all poured into the surrounding rivers, causing muddy sandy water, various domestic sewage and industrial sewage to be discharged into the river in large quantities, resulting in river pollution. It is very serious. Over time, the sediment in the river continues to accumulate at the bottom of the river, causing the water level of the river to rise, often flooding around the river, causing economic losses, and making it difficult to pass, causing traffic jams, and posing a greater safety hazard. [0003] Since the amount of sewage discharged into the river varies from day to day, especially in the rainy season, the flow rate and flow of the river will change at any ...

Problems solved by technology

[0002] At present, with the advent of the rainy season, rainwater, road drainage systems, various domestic sewage and industrial sewage, etc. are all poured into the surrounding rivers, causing muddy sandy water, various domestic sewage and industrial sewage to be discharged into the river in large quantities, resulting in river pollution. It is very serious. Over time, the sediment in the river continues to accumulate at the bottom of the river, causing the water level of the river to rise, often flooding around the river, causing economic losses, making it difficult to pass, causing traffic jams, and posing a greater safety hazard

[0003] Since the amount of sewage discharged into the river varies from day to day, especially in the rainy season, the flow rate and flow of the river will change at any time with the discharge of rainwater, making it difficult to guarantee the amount of treatment drugs added in the water treatment process, and it is also difficult to invest in water treatment equipment. The sewage cannot be treated efficiently, which greatly increases the difficulty of river water treatment
