新景矿污水处理提标改造技术方案的研究与分析

UPGRADING CONRESTRUCTION OF WASTEWATER TREATMENT PLANT IN XINJING COAL MINE

针对新景矿污水处理厂提标改造需求,分析了原有处理工艺在总氮、总磷、悬浮物去除能力上的不足,从设备完善、有机碳源补充、构筑物新建、化学除磷辅助、曝气量控制等方面提出解决方案。本方案实施后,总氮、悬浮物排放浓度达到GB18918-2002一级A标准要求。

Based on the requirements of upgrading reconstruction of Xinjing Coal mine wastewater treatment plant, the defects of original technical process were analyzed from the aspects of total nitrogen（TN）, total phosphorus（TP） and suspended particles removals. Solutions were proposed regarding equipment improvement, organic carbon addition, new buildings construction, phosphorus chemically removal and aeration control. After these solutions were applied, TN and suspended particles concentrations would satisfy Standard I-A in GB18918-2002.
