Because of the shortage of land for the project, it is impossible to arrange treatment equipment on the riverside bank, so a 164 M2 concrete overhead platform is set up at the flood passage place inside the riverbank revetment without affecting the drying up of the riverway. At the same time, a water intake regulating pool and an outflow landscape pool are set up to support the sewage treatment equipment. The project was completed at the end of April 2018 and operated normally. Leaders of relevant departments of Shiyan City have visited the site many times for guidance and inspection. Up to now, all the equipments have been running normally for a long time and the effluent meets the relevant requirements, which provides a good basis for the first batch of special supervision work of urban black and odorous water remediation carried out jointly by the Ministry of Ecological Environment and the Ministry of Housing and Construction in the Majiahe River Basin in June this year, and makes a new contribution to the protection of the water ecological environment of Shiyan City.
