最佳钻井防污土建结构的设计及应用

设计了一种高效实用的钻井防污土建结构，该结构与原结构相比能杜绝处理渣泥流入废水沉砂池参与废水循环，也可防止废弃钻井液和掏罐泥浆水直接进入沉砂池，因此能更好地控制钻井废水浓度，一定程度上提高钻井废水处理达标率，同时该结构具有对处理水进一步隔油、净化等优点，现场推广应用后得到证实。     

胜利油田生活污水调查及评价

随着人民生活水平的提高，城市人均用水量逐年增加，伴随产生的生活污水已经成为不可忽视的污染源。胜利石油管理局供水公司于１９９３年对胜利油田的污水排放情况进行了调查，调查各单位职工住宅区和机关办公区所排放的生活污水的情况，包括排放生活污水单位的名称、人数、生活用水量、污水排放量和污水水质等，并提出了生活污水的治理对策。

MODELING THE BUILDUP AND WASHOFF OF POLLUTANTS ON URBAN WATERSHEDS1

ABSTRACT: A model for urban stormwater quality was developed in this study. The basis for the model is the process by which pollutants build up on the watershed surface. For the wet climate of the study site, it was assumed that there exists an interval of time over which the pollutant buildup equals the pollutant washoff (no accumulation of pollutant). The buildup model was represented by a linear function of the antecedent dry time. The buildup function was then linked with a pollutant washoff model represented by a power function of the storm runoff volume. Various time intervals for no net accumulation were tested to calibrate the model. The model was calibrated to observed data for two small urban basins in Baton Rouge, Louisiana, and model results were used to analyze the behavior of phosphorus concentrations in storm runoff from these basins over a long period of time.     

PESTICIDES AND PESTICIDE DEGRADATION PRODUCTS IN STORMWATER RUNOFF: SACRAMENTO RWER BASIN,CALIFORNIA1

ABSTRACT: Pesticides in stormwater runoff, within the Sacramento River Basin, California, were assessed during a storm that occurred in January 1994. Two organophosphate insecticides (diazinon and methidathion), two carbamate pesticides (molinate and carbofuran), and one triazine herbicide (simazine) were detected. Organophosphate pesticide concentrations increased with the rising stage of the hydrographs; peak concentrations were measured near peak discharge. Diazinon oxon, a toxic degradation product of diazinon, made up approximately 1 to 3 percent of the diazinon load. The Feather River was the principal source of organophosphate pesticides to the Sacramento River during this storm. The concentrations of molinate and carbofuran, pesticides applied to rice fields during May and June, were relatively constant during and after the storm. Their presence in surface water was attributed to the flooding and subsequent drainage, as a management practice to degrade rice stubble prior to the next planting. A photo-degradation product of molinate, 4-keto molinate, was in all samples where molinate was detected and made up approximately 50 percent of the total molinate load. Simazine, a herbicide used in orchards and to control weeds along the roadways, was detected in the storm runoff, but it was not possible to differentiate the two sources of that pesticide to the Sacramento River.
