Research on the Technologies of In-situ Water Pollution Control

In-situ water pollution control technologies,including in-situ water pollution prevention technologies and in-situ water pollution remediation technologies, embody the idea of minimal contamination and maximal resource utilization in pollution control. In this article, the in-situ water pollution prevention technologies are summarized on the aspects of managing and selecting raw materials, optimizing techniques and process, and water reuse, and the in-situ water pollution remediation technologies are discussed on the aspects of in-situ bioremediation, in-situ plant remediation, and in-situ physical and chemical remediation. The significance of in-situ water pollution control technologies and the development trend of the teehnologies are also discussed.
