合理控制参数,保持活性污泥系统稳定运行

独山子石化总厂乙烯厂工业水车间是独山子地区第一个环保“三同时”项目,采用的污水处理工艺虽然还是工业废水处理的“老三套”,即隔油、气浮、生化处理,但生化系统采用了较先进的纯氧曝气法,生物缺氧接触氧化工艺。纯氧曝气池因安全问题未使用纯氧进行曝气,而是用空气曝气,因生化系统的运行参数是按纯氧曝气法设计的,实际运行时只能作参考。１９９８年５月大检修后,对生化系统的运行参数进行了定量化,生化处理效果有明显的改善,本文就其运行参数进行了探讨分析。１　影响生化系统运行主要因素的控制生化处理是整个污水处理流程中…

Feasibility of On-line Measurement of Sewage Components Using the UV Absorbance and the Neural Network

The objective of this study was to test the feasibility of a new method to improve the accuracy in the estimation of sewage components. Adding to the regression of sewage components with UV (ultraviolet) absorbance values, a proposed method considered an unclear but existing relationship among characteristic of sewage production. Sewage production showed very defined profiles due to the daily human activities. So the main idea was the combination of measuring the UV absorbance values and analyzing the characteristics of the sewage production. For this purpose, 446 sewage samples taken at every 2-h interval for 51 days at a wastewater treatment plant were statistically analyzed using neural network (NN). NN was trained with 350 data sets (about 29 days) of UV absorbance values, flow rate and time. And as a result, it could predict 96 data (12 days) as a validation, indicating that estimation accuracies were improved to higher level than those of the linear regressions. The proposed method could estimate concentrations of total nitrogen (TN) and total phosphate (TP) within practical accuracies as well as total suspended solid.

Impact Modeling of Sewage Discharge From Georgetown of Penang, Malaysia on Coastal Water Quality

Currently about 200,000 persons of the Penang Georgetown population is served by a sewerage system which conveys the raw sewage to an open channel flume in Jelutong for discharge into the Western Channel. This has resulted in the degradation of coastal water quality in the affected areas. Therefore, there exists an urgent need to look for other alternatives for sewage treatment and disposal. This paper presents the results of computer simulations on the impacts of sewage discharge on Penang coastal waters under two treatment and disposal options. The preferred option is a conventional activated sludge treatment system capable of treating the sewage to secondary level with a submerged outfall to the Western Channel for the disposal of the treated effluent. The results of computer simulations show that the quality of coastal waters, other than in the immediate vicinity of the discharge point, would be able to achieve the Malaysian proposed criterion for recreational waters up to year 2020.

Impact assessment of various parameters polluting Ganga water in Kolkata Region: a study for quality evaluation and environmental implication

The quality of sewage-sludge samples obtained in Kolkata region was evaluated. Both sewage water and sludge components were analyzed for a number of physico-chemical, microbiological parameters using standard laboratory procedures, some heavy metals by AAS method and pesticide contents by GC method. Some of the physical and chemical constituents of the samples are within the allowable levels while the rest are not. The samples are rich in nutrients and have suitable pH for agricultural uses. In terms of Electrical Conductivity and Sodium Adsorption Ratio, sewage water is not suitable for irrigation. Fecal and coliform bacterial population is high in all samples. Pesticide and heavy metals in some places are alarming. So sewage-sludge produced in Kolkata cannot be used for agricultural purpose without any treatment. Thus proper care, maintenance, treatment and disposal of sewage water and sludge are most vital and should be the prime thrust for the nation.
