The strategies include chemically enhanced settlement, pre-aeration, addition of N-adsorption media and P-adsorption media, high, middle and low water level and dynamic saturation line within the.
By preaeration in tanyard wastewater, the effect of primary settling improves obviously.

It is also indicated that the pre-ozonation can improve the removal efficiency of TOC and algae by aeration, and that the post-ozonation accelerates TOC removal by activated carbon filter.
