Waterfall type water quality purification system used at river and lake entrance

Abstract

The invention relates to the technical field of water quality purification, in particular to a waterfall type water quality purification system used at a river and lake entrance. The waterfall type water quality purification system comprises a stepped mounting table, a hydroelectric generation device, a water pumping device, a filtering and separating device, a medicament purifying device and a water plant purifying device, the filtering and separating device, the medicament purifying device and the water plant purifying device are sequentially distributed on the stepped mounting table in a stepped manner, the filtering and separating device is arranged at the top of the stepped mounting table, the input end of the medicament purifying device is arranged below the filtering and separating device, and the input end of the water plant purifying device is arranged below the medicament purifying device; a plurality of hydraulic power generation devices are uniformly distributed on the filtering and separating device, the medicament purifying device and the water plant purifying device; and the water pumping device is fixedly mounted at the input end of the filtering and separating device. According to the invention, the personnel cost is effectively saved, and the water quality evolution and improvement speed is increased.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a waterfall-type water purification system used at the entrance of rivers and lakes. Background technique [0002] In recent years, the environmental quality of surface water has been generally good, and the water quality has generally remained stable. However, from the monitoring sections of lakes and rivers, the overall situation is not optimistic. The water quality of some high-quality lakes and rivers has declined, and the water quality has dropped from Grade III to Grade IV or lower. The main impact indicators are turbidity, total phosphorus, chemical oxygen demand, and five-day biochemical oxygen demand. [0003] At present, in order to solve the problem that the water quality of lakes and rivers is not up to standard, the main measures are to control the amount of sewage discharge, let the water body recover from self-purification, and then manually clean the l...

Problems solved by technology

[0003] At present, in order to solve the problem that the water quality of lakes and rivers is not up to standard, the main measures are to control the amount of sewage discharge, let the water body recover from self-purification, and then manually clean the lake water regularly. It will take 5 to 10 years for the water quality to reach the level above, and the speed is relatively slow, and a large number of personnel will be required for construction.
