煤磨收粉系统的改造

武钢炼铁厂10t/h煤磨系统四套,采用三级除尘(旋风、多管与袋式除尘)和两级风机(排粉机与抽风机)的收尘系统。能耗高、尾气排放超标、故障率高、安全性能差。于1993～1996年相继对四套系统进行改造,获得令人满意的效果,实现节能、降耗、增产、安全生产,达到环保标准。     

吸附胶体浮选法处理电解钴废水的研究

采用吸附胶体浮选法处理电解钴废水。用十二烷基磺酸钠（ＳＬＳ）作浮选剂，用ＦｅＣｌ３和Ａｌ２（ＳＯ４）３作混凝剂，浮选后废水可达到国家工业废水排放标准（３ｍｇ／Ｌ）。为实际废水的处理提供了可靠的依据。     

The Impacts of Human Visitation on Mussel Bed Communities Along the California Coast: Are Regulatory Marine Reserves Effective in Protecting These Communities?

Rocky intertidal habitats frequently are used by humans for recreational, educational, and subsistence-harvesting purposes, with intertidal populations damaged by visitation activities such as extraction, trampling, and handling. California Marine Managed Areas, particularly regulatory marine reserves (MRs), were established to provide legal protection and enhancement of coastal resources and include prohibitions on harvesting intertidal populations. However, the effectiveness of MRs is unclear as enforcement of no-take laws is weak and no regulations protect intertidal species from other detrimental visitor impacts such as trampling. The goal of this study was two-fold: (1) to determine impacts from human visitation on California mussel populations (Mytilus californianus) and mussel bed community diversity; and (2) to investigate the effectiveness of regulatory MRs in reducing visitor impacts on these populations. Surveys of mussel populations and bed-associated diversity were compared: (1) at sites subjected to either high or low levels of human use, and (2) at sites either unprotected or with regulatory protection banning collecting. At sites subjected to higher levels of human visitation, mussel populations were significantly lower than low-use sites. Comparisons of mussel populations inside and outside of regulatory MRs revealed no consistent pattern suggesting that California no-take regulatory reserves may have limited effectiveness in protecting mussel communities. In areas where many people visit intertidal habitats for purposes other than collecting, many organisms will be affected by trampling, turning of rocks, and handling. In these cases, effective protection of rocky intertidal communities requires an approach that goes beyond the singular focus on collecting to reduce the full suite of impacts.

我国现行排污费征收办法及标准诸问题探讨

我国现行的排污费征收办法及标准存在着起征费的计征额时间界定不清、达标污水收费额高于某些超标污水的收费额，收费项目少、收费标准偏低，城市污水处理厂的排污费和监督管理不明确等一系列问题，应予以确定以增强执法的严肃性。     

某化工园区污水分类收集分质处理系统设计

为了提高某化工园区污水处理效率以及降低污水处理费用,园区环保部门拟对园区污水收集体系进行升级改造。改造方案采用分类收集分质处理的设计思路,同时创新型的采用OUR污泥呼吸法对企业废水分为难降解有毒、难降解无毒、可生化3类,3类废水进入不同的收集池后前2类废水进行芬顿+微电解预处理,可生化类别直接进入生化系统。该种工艺路线较传统的全部接入进行预处理的方法更具先进性、高效性和经济性,可作为一种先进理念的收集体系使用到其他工业园区中进行推广应用。
