摘要
根据工程实际情况和治理面积投加适量的Eama-11生物抑藻剂等3种复合生物制剂,对西土城沟水绵以及黑苔爆发现象进行治理。并对技术应用过程中水质指标和水绵抑制程度的变化进行监测,结果表明:西土城沟经生物抑藻技术治理后能够有效抑制水绵的生长,水绵得到了有效的控制;水体水质得到改善,景观效果得到显现。
According to the actual situation and management area of engineering, three types of bio-agents including Eama-11 Algae Inhibiting Agent were used in the treatment of Xitucheng ditch, in order to manage the outbreak phenomenon of Spirogyra and black moss. In the end, evaluating the governance effect of composite biological agents by the variation of water quality indicators and the inhibition degree of Spirogyra during the application process. The results showed that the composite biological agents could inhibit the growth of Spirogyra effectively in Xitucheng ditch. In addition, water quality of water body was improved obviously, landscape representation was restored.
