Pollutants-Producing and Pollutants-Discharge Coefficients of Nitrogen and Phosphorous in Rural Domestic Sources in Taihu Lake Basin, China

Article Preview

Abstract:

Nine households of high, medium and low income level were selected as representative household of the Taihu Lake basin, China to study the measuring method of pollutant producing coefficient (PPC) and pollutant discharge coefficient (PDC) of rural domestic sewage and organic waste. Results showed that the income level had no significant influences on TN-/TP-PPC of rural domestic sewage but substantially affected the production and TN-/TP-PDC of domestic sewage, as well as the production and TN-/TP-PPC/PDC of organic waste, which corresponded with income such that high-income farmer households produced the most and the middle income produced lesser and the low income households produced the least amount. The utilization and treatment efficiency of toilet wastewater and the comprehensive utilization rate of organic wastes, particularly the rate of livestock were the primary influencing factors of domestic sewage and waste PDC. These factors were substantially affected by agricultural income level and septic tank type.
