科技园区试验废水近零排放技术路线探索

Exploration on the Near-Zero Discharge Technical Roadmap of Experimental Wastewater in Science and Technology Park

摘要: 20世纪80年代以来，我国园区经济快速兴起和发展，在取得良好经济效益的同时，也面临日益严格的水环境治理问题，科技园区试验废水的“近零排放”成为水污染治理的主要发展趋势。本文以某科技园区试验废水为例，介绍了废水的来源、水质特点和排放要求，探索科技园区试验废水近零排放的技术路线、高浓度镉氨废水零排放的技术方案、工艺流程和系统运行情况，对类似科技园区环保设施的设计、建设、运行和管理提供了借鉴和参考。

Abstract: Since the 1980s, park economy has risen and developed rapidly in China. While sizeable economic benefits achieved, it is facing strict water environment treatment problems. The “near-zero discharge” technology becomes main trend of wastewater treatment in science and technology parks. Taking the experimental wastewater of some science and technology park as an example, this article introduces the sources of wastewater, water quality characteristics, and discharge standard, explores near-zero discharge technical roadmap, high concentration cadmium ammonia wastewater treatment technical scheme, process flow and operation. It provides a reference for the design, construction, operation and management of environmental protection facilities in similar science and technology parks.
