大红丙烯酸油漆着色剂替代及其综合利用研究

清洁生产与资源综合利用是人们持续研究的课题,笔者在大红丙烯酸油漆着色剂"颜料红GL"替代"镉红颜料"中,开展了颜料红GL随温度、时间变化与热塑性丙烯酸树脂、有机硅助剂、二甲苯最佳浓度配比,确保着色效果及其资源综合利用等一系列试验,实现了年综合利用工艺冲洗水25.6万吨,减排CODcr 218.24吨、总镉:油漆中8031.5吨,废水中0.41吨、固废中0.088吨,提高了产品市场竞争率。     

卢氏县集中式饮用水水源保护区划分研究

划分水源地保护区是保障饮用水资源可持续利用的重要措施。在卢氏县集中式饮用水水源保护区的划分工作中,根据《饮用水水源保护区划分技术规范》(HJ/T338-2007),采用现场调研和卫星遥感技术相结合的方法,结合饮用水水源保护区的地形、地标、地物的特点,科学地对卢氏县地下水型、河流型、湖泊型水源地进行保护区划分,并提出卢氏县饮用水水源保护区范围、面积及目标,为卢氏县饮用水源保护规划奠定了理论基础。针对卢氏县饮用水源的特点,提出可行的建议和措施,为下一步饮用水源的保护提供科学依据。

Status and Trends of Dissolved Oxygen in Corpus Christi Bay, Texas, U.S.A.

The purpose of this studywas to determine status and long-term trends of dissolved oxygen concentrations (DO) in Corpus Christi Bay, Texas, U.S.A. A 20-year record of randomized stations was used to determine the trend of surface water DO, salinity, and temperature over space and time. A 13-year record of two fixed stations was used to determine the temporal nutrient trends. A 10-year record of fixed stations in the southeastern region of Corpus Christi Bay was used to determine the status of disturbance caused by low DO in bottom waters. From 1982 to 2002, there was a significant decrease in surface water DO at a rate of 0.06 mg L⁻¹ yr⁻¹ and a significant increase in surface water temperature at a rate of 0.07°C yr⁻¹. The southeastern region of Corpus Christi Bay had the lowest average DO, and during July and August, DO are steadily declining at a rate of 0.09 mg L⁻¹ yr⁻¹. It is not likely that eutrophication is causing hypoxia, because freshwater inflow rates have significantly decreased since 1941 and nutrient levels have not changed from 1987 to 2000. Even though long-term trends indicate that average surface DO is decreasing, disturbance by hypoxia appears to be stable, but this may be due to just eight years of data. In fact, if the current trend continues, surface water DO will not meet exceptional aquatic life standards (≤5 mgL⁻¹) in 2032.     

中国规划环评中协调性分析的作用

协调性分析是规划环境影响评价的重要组成部分,它的分析对象是被评价的规划草案及其相关的政策、法规、规划等。在以规划草案为评估对象的环境影响评价中,协调性分析能够起到两种作用：解释制定规划草案的“政策背景环境”,和检查规划草案是否存在资源保护、环境保护方面的缺陷和不足。这两种作用不能被截然分开。协调性分析的目的是帮助环评单位和公众更好地理解规划制定的背景,以及使规划环评针对草案的缺陷与不足提出相应的环境目标和环境保护对策。分析结果一般可以使用矩阵来表示。如果规划环评可以早期介入到规划的制定中,描述“政策背景环境”和制定可选择性方案这两个程序就可以达到协调性分析的目的．因此不再需要进行专门的协调性分析。     

An integrated assessment method of urban drainage system:A case study in Shenzhen City,China

In recent years, the urban drainage system in China is facing the dual pressure of renovation and construction. This requires that the integrated assessment for the planning and operation of the urban drainage system is obligatory. To evaluate the urban drainage system, an integrated assessment methodology based on the analytic hierarchy process (AHP), integrated simulation, and fuzzy assessment is established. This method is a multi-criteria decision adding app roach to the assessment of the urban drainage system comprehensively. Through the integration of the Storm Water Management Model (SWMM), a simple wastewater treatment plant model, and a surface water quality model, an integrated modelling system for the urban drainage system is developed and applied as a key tool for assessment. Using the established method, a case study in Shenzhen City has been implemented to evaluate and compare two urban drainage system reno vation plans, the distributed plan and the centralized plan. Because of the particularity of this case study, the established method is not applied entirely. Considering the water environ mental impact, ecological impact, technological feasibility, and economic cost, the integrated performance of the distri buted plan is better. As shown in this case study, the proposed method is found to be both effective and practical.
