Project Title Study on the screening and amplified culture of oily sewage treating microbial strains
Project Abstract According to the effluent standards of Environment Protection Agency for the industry, sewage systems and urban sewage treatment facilities, oil concentration may not exceed 10 ppm. However, it is difficult for current urban sewage treatment facilities to reach this standard. If effluents that failed to reach this standard, fats and grease will often obstruct the sewage pipelines and sewers, and increase the organic loading of the downstream sewage treatment plants. Additionally, the use of traditional chemical treatment will result in accumulation of waste sludge and increase costs of cleaning and transportation. This study will develop a sewage treatment framework by using natural microbes and develop an effective biological agent for treatment of highly oily and greasy sewage from domestic hotels, food courts, wholesale stores and food industries. The project will screen the excellent oil-degrading microbial strains that will reduce the oil contents from 1000 ppm to 10 ppm within 24 hours; and establish a rapid testing platform to test the oil concentration in effluent water within 2 hours for the benefit of real-time monitoring. In addition, the project will search for the optimal culturing conditions for advantageous oil-degrading microbial strains, and also conducts small scale quantified tests, with fermentation projected to produce bacterial concentration at 1×109 CFU/mL

Project Title Commercial application and treatment of sewage from urban restaurants industries to meet secondary treatment standard by oil degrading microbes
Project Abstract This project plans to utilize the specificity and reproducibility of microbial system and develop a sustainable microbial oily sewage treatment reagent, for use in treating drainages from the urban restaurants to not only meet the government-stipulated effluent standards, but also the higher standard of secondary effluent. We hope to create a triple-win solution with our project to reduce the sewage contamination to meet the government effluent standards for the urban restaurants, and to expand business profits for our company. We plan to use the oil degrading reagents made from oil degrading microbial strains that were screened in the past by our collaborating laboratories, and conducted microbial oil degradation tests in sewage treatments, with the assistance of well-known academic department and an environmental protection company. The project will utilize an automated sewage treatment system built by the environmental protection company, and use the aforementioned microbes in the specific drainage pools during different stages of sewage treatment. We will also conduct normal day and weekend effluent tests with the rapid measurement of chemical oxygen demand and oil content, ensuring that the established treatment process will be fully functioning under the change of sewage volumes and component changes during different time periods. The treatment process is designed to reduce the oil content, COD, BOD and SS to 10, 30, 30 and 30 ppm or below, respectively, within a time period of 4 hours. We hope such process will comply with the higher quality of secondary effluent standard and achieve the ultimate goal of reclaiming water resources.
