Ecological behaviour of priority organic pollutants in land treatment systems of municipal wastewater and their control strategies

Abstract

Abstract: Ecological engineering land treatment system(LTS) is suggested as a good pratical technique series with multiple functions and goals in protection of water bodies and purification of municipal wastewater into renew resource under the guideline of ecological principles, and hence, it is a vital area in study of applied ecology. Through optimization of site selection, rational design, good operation and sound managenment as required, it would be able to play an important role in protection environment and promoting economic development. It should be stressed that priority organic pollutants and eco-environmental problems caused by them might be the limiting factor for implementation of ecological engineering LTS in practice. In this paper, a comprehensive review was given on the basis of combination of theory with practice, which covers some essential topics such as purification function, ecotoxicological effects and ecological risk evaluation, etc. However, the main aim is to provide a solid foundation for the effective control and manipulation of priority organic pollutants with LTS.

Key words: Priority organic pollutants, Municipal wastewater, Land treatment system, Ecological behaviour, Ecological effect, Purification function, Ecological risk assessment
