通常污水中,印染废水占85%左右,同时还有15%左右的生活污水及其他各种医药、制革等工业废水,属于典型的综合性工业废水。

污水站生物除臭技术

污泥均质池由于本身含有大量污泥,是臭气集聚区,同时在池底曝气又加速了臭气从水中散发到空气中,因此,不管是臭气浓度,还是氨气、硫化氢的指标都超标严重,对周边环境的影响较大,很有治理必要性。

生物除臭技术应用于城市污水厂、炼油厂的工程实例较普遍,具有操作方便,运行成本低,达标效率高等特点,在前期完成对进水稳流池进行生物除臭应用取得较好效果的前提下,本次污泥均值池也使用生物洗涤过滤工艺进行臭气治理。

生物除臭系统

收集的臭气通过气体输送主管经风机抽送到生物洗涤装置上部的进气口,雾化喷嘴将水充分雾化后与气流混合,迅速使待处理的气体湿度达到饱和状态,为生物过滤工序的稳定运行创造良好的条件。

经生物洗涤装置加湿后的饱和气体由下而上进入生物过滤装置,在气体由下而上运动时,气体中的异味分子穿过填料层,与填料表面形成的生物膜充分接触,被微生物氧化、分解,异味分子被转化为二氧化碳、水、矿物质等,从而达到异味净化的目的。

经生物过滤装置处理后的气体经由15m排放管高空达标排放。除臭装置为露天放置,24小时连续运行,保证硫化氢去除率在95%及以上。溶液过滤循环装置中设置加热系统及温度计,用以保证生物洗涤过滤除臭系统处于适合微生物生长的最佳温度环境。
