Abstract: |
This paper researched on slightly polluted surface water treatment technologies of Tonghui River Tongzhou part, selected three combined processes as aeration biological filter + coagulation sedimentation、 anaerobic biofilter + biological contact oxidation and electrochemistry oxidation + constructed wetland. Experiment results showed the effluent indexes such as ammonia nitrogen, total nitrogen, total phosphorus, CODcr fulfill the (GB3838-2002) grade V, inside the total nitrogen concentration far below 15mg/L-the objective of research project, meanwhile compared with operation, maintenance and processing costs per ton wastewater.
