Comprehensive Index Analysis on Water Quality in Lingjian Creek

Abstract:

Lingjian creek is an important branch of the Li-river.It has been badly polluted because of lacking of controlling the waste water emissions in recent years.This paper provides some countermeasure and advice about how to control the waste water emissions strictly through monitoring each section of Lingjian creek, analyzing the comprehensive pollution condition, the pollution characteristics and pollution regularity. The results show that:TN and TP are the most serious problems. The average value of TP is 4.5mg/L which is as much as five-times higher and TN is even as much as seventy-times higher. The comprehensive pollution index from high to low is: TN, TP, COD and TOC. Nitrogen and phosphorus sources are the main pollution sources.The author hopes to provide some suggestions not only for protecting Lingjian creek and Lijiang river, but also for keeping the sustainable development of Guiling tourism.
