From the four aspects, direct treatment effect, treatment ability, treatment stability and impact load resistance, the thesis quantitatively analyzes the treating effect of normal contamination removal ( ss, bod5, codcr ) and nitrogen and phosphorus removal ( nh3 - n, tn, tp )
從污水處理的直接效果、處理能力、處理穩定性和耐沖擊負荷能力四個方面，對各工藝普通污染物（ ss ， bod5 ， codcr ）和脫氮除磷（ nh3 - n ， tn ， tp ）的處理效果進行定量分析。 -
Moreover, the thesis analyses the biodegradation of petroleum products, evaluates the biological degradation properties of the developed environment friendly base oil and as well the lubricant ' s biodegradation properties at actual conditions by means of self - designed soil simulation and also in water by testing bod5 / codcr values
分析了石油類產品的生物降解機理，對所研製的環境兼容基礎油的生物降解性進行了評價，通過自行設計的土壤模擬法評價了潤滑油在實際環境中的生物降解性，採用測bod _ 5 cod _ （ cr ）值法來評價潤滑油在水中的生物降解性。 -
Second, based on the characteristic of the receiving water studied in this paper, develope a dynamic one - dimension water quality model for nanbei river in zhangcha town of foshan city, and develope a program of water quality model based fortran powerstation. and then, calculate the concentration of codcr in receiving water using the simulation results of swmm and analyze the effect on the environment of receiving water by intercepting ratio. at last, the construction investment and operational and administrative expenses of intercepting trunk sewer 、 pumping station and sewage farm is calculated and the relation between them is discussed
其次，本文根據研究區受納水體的特點，建立了佛山市張槎鎮南北大涌的一維非穩態水質模型，相應地開發了基於fortranpowerstation平臺的水質模型計算程序，並在swmm模型模擬結果的基礎上，利用本文編制的水質模型程序計算了不同截流倍數時南北大涌codcr濃度的時空變化過程，分析了截流倍數對河涌水環境質量的影響。
