覆盖排查识别、制定方案、治理工程、效果评估、长效管理,农村黑臭水体治理有了新一轮“路线图”。日前,生态环境部办公厅正式天下棋牌《关于印发<农村黑臭水体治理工作指南(试行)>的通知》(环办土壤函〔2019〕826号)。
更早之前,2019年7月《关于推进农村黑臭水体治理工作的指导意见》正式落地的同时,吹响了农村黑臭水体的治理号角。紧接着,九部门联合印发的《关于推进农村生活污水治理的指导意见》明确推进农村黑臭水体治理,采取控源截污、垃圾清理、清淤疏浚、水体净化等综合措施恢复水生态。自此,备受关注的黑臭水体治理,不仅于城市而言。

具体来看,当开展公众评议有困难时,通过水质监测判定是否黑臭。水质监测指标包括透明度、溶解氧、氨氮3 项指标。具体数值为透明度低于25cm、溶解氧低于2mg/L、氨氮大于15mg/L。对西北地区、长江中下游地区等区域含泥沙量较大的水体,当只有透明度指标不达标时,不判定为黑臭水体。
在实地调查和环境监测基础上,确定污染源和污染状况。污染源排查方面兼顾点源和面源,前者强化包括排污口情况,以及相应指标的时间、空间变化特征。后者则将根据区域和季节性变化特征,覆盖土地利用类型及面积、施肥量、畜禽养殖类型及其污染治理情况、河面及岸边垃圾堆放情况等。
