Methods of Reservoir Water Pollution Control and Water Quality Improvement

In this chapter, the common technical methods, including physical, chemical, and ecological control techniques, for improving the water quality of lakes and reservoirs are briefly introduced. The physical control technologies mainly include the mixing–oxygenating technology, dilution and scour, sediment dredging, and coverage. The chemical control technologies mainly include phosphorus precipitation and passivation, restoration of acidified lakes or reservoirs, and sediment oxidation. The ecological control technologies mainly include bioremediation, phytoremediation, and biomanipulation remediation. By analyzing and comparing the tested data, for water sources such as reservoirs, the mixing–oxygenating technology is more suitable for decreasing endogenous pollution and controlling eutrophication.
