Study on High-salinity Oil Extraction Wastewater Treatment with Immobilized Microorganism Particles

摘要

According to high-salinity oil extraction wastewater treatment experiments with immobilized microorganism particle (IMP), the prime factor conditions were that: PVA 10%, sodium alginate 2.5% and CaCl2 1%. Furthermore, the physicochemical property of IMP was optimum with the crosslinking agent at pH of 6.8, the reaction time of 22 h and the inoculation amount of 10%. High-salinity wastewater was treated by IMP with the solid-liguid ratio of 80 particles to 100 ml wastewater, and the COD removal rate was 51.49%.
