洗車場廢水前瞻處理技術試驗計畫

中文摘要 近年來臺灣環保意識興起、環境議題日受重視,而都會區人口集中,洗車需求大幅增加,清洗車輛使用之清潔劑隨著洗車廢水排入側溝進入水體,造成一定程度之污染。而洗車場約略可概分為機械式洗車以及人工或自助洗車,且因洗車規模相對較小,大多未設置廢污水處理設施。規模的區隔可以最大日廢水產生量20 CMD作為基準,洗車廢水若未經妥善處理,不僅有礙市容觀瞻,也污染水體水質。現行法令規定廢水產生量一天達20噸以上且有自動洗車設備之業者,需要申請排放許可證;然其他規模較小業者現階段則無法可管,廢水亦無法納管處理。因此本計畫擬開發適當之設備,處理中小洗車業者產生的洗車廢水,解決用地不足的問題,進而推廣輔導業者使用該技術。 現地試驗旋濾與電混凝浮除技術的組合,可將洗車廢水處理至放流水標準。本計畫另於自助洗車現場設置廢水收集截流溝、汲儲水設備,並分別驗證兩種技術單獨或串聯使用四種處理模組,以組合式處理效果較佳。先電混凝浮除之方式會產生較多一點之污泥,但濾材壽命可延長,獲得之處理水水質較佳;先旋濾之方式較不會產生污泥,處理後水質稍差些;惟差異並不會太大,可視洗車廠所自身之成本考量選用。

Test plan for forward-looking treatment technology of car wash wastewater

英文摘要 In recent years, Taiwan's environmental awareness has risen and environmental issues have received increasing attention. The population in the metropolitan area is concentrated and the demand for car washing has increased significantly. The detergent used to wash the vehicle is discharged into the sewer systems with the wastewater from the car wash, causing a certain degree of pollution. The car wash can be roughly divided into mechanical car wash and manual or self-service car wash. And because the scale of car wash is relatively small, most of them do not have wastewater treatment facilities. Its maximum daily wastewater production can be slightly separated by 20 CMD. If the car wash wastewater is not properly treated, it will not only negatively affect urban appearance of the city, but also pollute the water quality. The current law stipulates that automatic car washing companies that produce more than 20 CMD of wastewater with automatic car washing equipment and need to apply for a discharge permit. The emerging car wash industry is currently small in scale and difficult to manage. Therefore, this project plans to develop wastewater treatment equipment to recover car wash wastewater generated by small and medium-sized car wash companies. It is hoped that the economic benefits of recycling will solve the problem of insufficient land, reduce the cost of wastewater treatment that small and medium-sized car wash companies can not manage. The project is to promote small and medium-sized car wash companies to use this technology to solve the current problems in the car wash industry. The combination of on-site test cyclo-flow filtration technology and electric coagulation flotation technology can treat car wash wastewater to meet the discharge water standard. Other necessary facilities, including raw wastewater collective ditch, water pumping and storage equipment have also been set up at the self-service car wash site. Four testing moduls that the two technologies are used alone or in series were verified, indicating the combined moduls obtained better results. The method of first electric coagulation flotation will produce slightly more sludge, but the lifetime of the filter material can be prolonged, and the quality of the treated water obtained is better; the method of first cyclo-flow filtration produce less sludge, while the water quality after treatment is slightly worse. However, the difference between two in-serial modules was not significant. The owner could adapt different modules based on the condition of the car wash factory.
