  • Abstract In this study, the the Pingtung City sewage system - liukuaicuo wastewater treatment plant as nitrogen, phosphorus removal effective evaluation and discussion. The liukuaicuo wastewater treatment treatment plant for the livelihood of sewage treatment plants, sewage collection source for the Pingtung City sewer and storm sewer closure sunny sewage biological treatment systems go "biological nitrogen and phosphorus removal (Biological Nutrient Removal, BNR ), will properly handle the effluents discharged to the receiving water body. However, because of the wastewater treatment plant intake water volume only up to half of the original design of water approximately 25,000 CMD, coupled with motivated stream water quality biochemical oxygen demand (BOD) and chemical oxygen demand (COD) on the low side, cause biological nitrogen and phosphorus way difficult to operate and nitrogen and phosphorus removal rate is not high. With the river basin water quality protection and water pollution control gradually attention, sewage treatment plant processing efficiency and pollutant removal types of demand relative, and the sewage treatment plant effluent nitrogen, phosphorus and follow-up will also be a control of the effluent standards project, the research house at liukuaicuo wastewater treatment plant - plant as the preparation of the assessment of biological nitrogen removal effectiveness of phosphorus removal system, and early response to future effluent nitrogen and phosphorus under control. This study was to compare two different sets of operating mode (activated sludge and bio-go nitrogen and phosphorus removal), for the sake of the truth of the study and to the same period (October 2011 -2012 in March and October 2012 -2013 in March) as a basis of comparison. The results of this study show that the operation of the treatment of the activated sludge method, the biological treatment system and final settling tank system to go than the biological nitrogen and phosphorus removal method electricity savings of 120,442 kWh, equivalent to 8%, in addition, in the effluent water quality, biological and chemical the value of oxygen demand (BOD), chemical oxygen demand (COD), suspended solids (SS), total nitrogen (TN) and total phosphorus (TP), activated sludge biological nitrogen and phosphorus removal method is to go no obvious difference; but in terms of total nitrogen (TN), biological nitrogen removal and phosphorus removal method is the initial value is higher than the activated sludge method but with the operating time is longer, there is a trend to decrease, and total phosphorus (TP), bio-go nitrogen and phosphorus removal method is slightly higher, but the terms of the total removal rate compared to the removal rate of biological nitrogen removal and phosphorus removal method is water quality parameters were higher than the activated sludge, biological nitrogen removal and phosphorus removal method is multi-faceted co-ordination, and can still play features and benefits.
