摘要:

以农村黑臭水体及底泥为研究对象,通过设置不同的处理模式,研究了曝气及曝气联合菌剂对农村黑臭水体污染物及黑臭底泥的治理效果,并对各运行工况下的水质提升效果进行了评价。结果表明,与静置组相比,采用各工况处理后,水质均显著提升,由初始的重度黑臭提升至非黑臭水体,其中,普通强度曝气技术(工况2a)对上覆水水质的提升效果最好,且简便易行;采用各工况处理后,底泥色泽逐渐由黑色变为土黄色,气味由强烈变为微弱,底泥有机质含量减少。

Abstract:

Taking the rural black and odorous water body and sediment as the research object, the treatment effect of aeration and aeration combined with bacteria on the pollutants was studied by setting different processing modes, and the effect of water quality improvement under various conditions was evaluated. The results showed that compared with the static group, the water quality of each treatment condition was significantly improved, from initial severe black odor to non-black odor water. Among of them, ordinary intensity aeration technology(working condition 2a), which was simple and easy to operate, had the best improvement effect on the water quality of the overlying water. After each treatment condition, the color of sediment gradually changed from black to earth yellow, the odor changed from strong to weak, and the organic matter content of sediment decreased.

Key words: aeration, bacteria agent, rural black and odorous water, sediment
