摘要
姚北平原河网水体榨菜废水污染严重,根据废水的排放特点,分卤水落水前、卤水落水期和卤水落水后3个典型时段对河网水质进行监测,结果表明,其污染类型为有机污染。基于榨菜废水排放的分散性和不定期的特点,提出人工湿地系统治理榨菜废水污染的方案设想,并就工艺流程、耐盐型水生植物等进行了初步探讨。
Based on an investigation of severe river-net pollution by wastewater from preserved Slchuan pickles at Yaobei Plain, the water monitoring was carried out at three typical periods, that is, before discharge, discharge and after discharge. The results showed it was a kind of organic pollution. Considering scattering and fugitiveness of the wastewater discharge, the constructed wetlands for treating the pollution is proposed. And the discussion about the technical process and salt-resistant hydrophytes is conducted.
