Abstract
The polluted coastal water of Shenzhen Bay was treated with composites of active materials, bacteria and algae as well as combinations of two or three of these composites. The water quality was then examined after 10 days with a focus on 8 parameters, including dissolved oxygen (DO), suspended substances (SS), turbidity (Turbidity), ammonia nitrogen (NH4+-N), total nitrogen (TN), total phosphorus (TP), chemical oxygen demand (COD) and harmful marine vibrio. The results showed that the water quality was dramatically improved and the levels of harmful marine vibrio were significantly reduced after the treatment with the combination of active materials, bacteria and algae. The three composites can improve the rate of DO by 89.08% and had the highest removal rates of NH4+- N, TN, TP, COD and harmful marine vibrio (HMV), at 92.59%, 94.05%, 90.05%, 94.12% and 98.21%, respectively. However, the removal rates of SS and turbidity were the highest for the treatment with active materials compound with bacteria, at 95% and 92.69%, respectively. The combination of the three composites clearly had the best treatment effect for the restoration of polluted coastal waters. This study established solid theoretical and practical foundations to control coastal pollution and restore the coastal ecology.
