长沙经济技术开发区水质净化工程有限公司是长沙经开区直属国有独资企业,此次项目所在地为位于长沙县星沙镇大塘村的星沙污水厂,设计污水处理规模为12万m3/d,于2003年投产运行。
污水处理厂生化系统所产生的剩余污泥处理处置是当今世界环保课题的一大难题,有效减低污泥含水率,避免剩余污泥在污水处理过程中产生二次污染,提高污泥作为再生资源的有效利用是世界各国共同重视的问题。处置剩余污泥的传统方法容易造成二次污染,成本较高,也无法将脱水后的污泥含水量降到60%以下。我司针对该技术瓶颈,结合剩余污泥的特性及污泥处理现状,采用“破膜聚沉湿法处理剩余污泥技术”,能使处理后的污泥含水率降至50%以下,使污泥减量、稳定、无害,实现污泥较好的综合利用,且投资省、见效快、节能减排,解决了常温深度脱水的世界性环保难题。
