Summary of the aquatic ecosystem in the treatment of the status quo, on the water through the various types of biological growth habit, for the purposes of their respective characteristics, described how they formed in the water environment in addition to not affect the self-survival but also to surrounding pollution. To maximize the quality of the clean up and, from the removal of nutrients in water inhibit the growth of algae treatment of refractory pollutants and heavy metals in the sewage containing many aspects, such as temperature and pH light at the time made a specific analysis and narrative To clarify the impact of the treatment effect of the major factors and the presenc
