The regulations for organics content in the effluent wastewater (40 mg/L BOD and 150 mg/L COD) currently in force in Macau are higher than those of many other developed regions. What makes the situation even worse is that the nutrient components (e.g., various nitrogen and phosphorus compounds) in the effluent wastewater being directly discharged into the open sea are not yet being monitored and regulated. Such effluent wastewater, without a proper treatment in terms of both organics and nutrients, would result in a lot of environmental problems which may take generations to resolve. In this project, the mixed liquor suspended solids collected from the Taipa wastewater treatment plant (WWTP) on Taipa Island in Macau SAR, China, were seeded into the lab-scale sequencing batch reactor (SBR). The real influent wastewater obtained from the said plant was pumped into the SBR for the reactions of organics and nitrogen removal. Different operational modes and lengths of reaction periods were tested, and measures to facilitate nitrification and denitrification were derived. Furthermore, the effects of chloride concentration in the course of salinity period were also explored. Results showed that the removal efficiency of ammonium-nitrogen was up to 95% while that of organics, measured as COD, was up to around 80% for the 6-hour cycle and 95% for the 9.5-hour cycle, respectively. The external carbon source, methanol in this study, did show a positive effect on denitrification, with a little less than 30 mg/L nitrate commonly obtained in the effluent wastewater coming out of the reactor. The organics removal efficiency was not compromised after the addition of external carbon, that is, 85% removal efficiency was still maintained. This study showed that the effluent wastewater coming from the reactor met the regulations currently in force in Macau. In addition, Taipa and Coloane WWTPs are at present being operated in a so-called "UNI-Tank" system, which is comparable to the SBR process. As a result, this research would gain a better insight into the practicability of modifying the existing operational modes of the WWTPs to achieve the simultaneous removal of organics and nitrogen. In Macau, 98% of the total drinking water sources come directly from the mainland China. This fact highlights Macau`s passive characteristics in terms of drinking water supply. While the high-quality water is a must if Macau is to emerge as a major leading tourists` city of the region, arranging an up-to-standard wastewater treatment, which permits a certain degree of effluent wastewater reuse, is an effective way to ease Macau`s drinking water shortage, especially during the salinity period. And this research would be a pioneering study into the feasibility of wastewater reuse in Macau in the near future and as a consequence, would right Macau onto the track of sustainable development.
