The Effect of Water Purification Ecological Engineering on the Cao Yang Round Creek

It nas been proved that planting various aquatic vascular plants with proper arrangements of time and space in tne eutropnic water of tne Cao Yang Round Creek nas formed an effective and stable ecological system for purifying water. Within two years, the water quality of the Round Creek has been improved significantly. The density of algae (content of chlorophyll a) has dropped by 95%, the total suspended solids is decreased by more tnan 90%, and COD is also reduced by 50%. The transparency of the water has increased from 15cm Before treatment to 53cm after treatment. Some parts of tne Creek are clear enough to see the bottom, to count tne fish. At the same time, beautification and planting of plants on the water surface has been carried our, together with the purification of the water. In this way, tne sightseeing value of water body is also increased.

The paper intends to probe an efficient way of harnessing the eutropnic water By practicing witn purification, Deautification and plant planting all at one time.
