Secondary water supply equipment was designed based on the current water supply source and municipal pipe network. The combination between Water purification and pressure-superposed water supply could guarantee the drinking water security, fully exploit the municipal pipe network pressure, and effectively save the energy. Catalytic oxidation of ozone, complex adsorption, and microbial degradation collaborated to treat the micro-polluted water. Activated alumina was employed for the high fluoride water purification with HCl/NaOH deep regeneration. For the brackish water, membrane treatment was adopted. A collaborative technology of ozone oxidation, contact oxidation, and biological oxidation was used for the iron/manganese-rich water. The results showed that all the effluents could meet the requirement of "Sanitary standard for drinking water" (GB5749-2006) and "Water quality standards for fine drinking water" (CJ94-2005).
