高锰酸钾法处理对硝基苯乙酮生产废液和废渣

对硝基苯乙酮生产中的碱洗液含有硝基苯类化合物,对环境有较大的危害,不可直接排放。实验提供了一种简便的处理方法,变废为宝,有明显的经济价值。在碱洗液中加入KMnO4进行氧化脱色后,经中和反应得产品对硝基苯甲酸。     

母题的重复与变异－洛阳大学图书馆立面设计

“母题法”是一种构成方法,它经常被应用在建筑立面设计中。这种构成方法通过同一母题的重复与变异,使建筑在统一中富于变化,母题的选择往往传达某些文化上的信息,对建筑起到一定的净化作用。介绍了这一方法在洛阳大学图书馆立面设计中的应用。     

RESILIENT ECOLOGY AND LANDSCAPE SYSTEMS OF THE FENGXINGLONG ECOLOGICAL PARK,SANYA

In the past 30 years, Sanya has developed into a high-density city with fragmented ecosystems and bottlenecked urban development. In April 2015, the Ministry of Housing and Urban-Rural Development proposed “Ecological Restoration and Urban Remediation” for Sanya and prioritized the Sanya and Linchun Rivers — two rivers that run through the central city — as core causes. The Fengxinglong Ecological Park project is located at the junction of the two rivers in downtown and its surroudings are occupied for various land uses. Diversified urban interfaces, abundant green space, and numerous ecological contradictions make the site critical for the remediation and restoration of waterways in Sanya. Through a series of resilient landscape design interventions, Fengxinglong Ecological Park catches, stores, and purifies rainwater to reduce river pollution and flooding disasters in addition to offering recreational funtions. As a valuable “urban sponge” and comprehensive resilient ecological park, it has helped restore the historic ecosystem and realized the intensive use of resources.     

填料式喷水室空调机组的节能及净化研究

本文针对现在空气污染严重,空调系统能耗大等问题,提出了一种新型填料式喷水室空调机组。该空调机组与传统式空调机组相比,具有节能、环保、净化等优点。空气与水直接接触,其热湿交换效率高且净化效果好,可达中效过滤器水平。风机及水泵能耗小,冷水机组制取高温冷冻水,耗电量小,节能效果明显。
