摘要: 针对传统黑臭水体修复治理技术存在投资和维护成本高等问题,应用自主研发的由水体自洁装置和磷高效吸附制剂组成的水体活化技术工艺包开展为期约130天的黑臭水体治理和修复应用示范,主要目标将超标因子氨氮(NH3-N)、总磷(TP)浓度从劣V类提升至III类。结果表明:水体自洁装置运行100天后,水体NH3-N从4.00 mg·L-1削减至1.00 mg·L-1,高效磷吸附制剂应用4周后,水体TP从0.42 mg·L-1降低至0.20 mg·L-1,NH3-N和TP均从劣V类改善到Ⅲ类,达到示范目标要求,断面间成对T检验表明水体活化技术工艺包对NH3-N和TP有明显的改善作用。与其他工艺相比,工艺包吨水投资约为13.89元,单台水体自洁装置运行电费约2.88元·d-1,吨水运行费用约为0.13元,具有较强的性价比,可为黑臭水体修复治理技术提供降本增效方案。
