Research and Practice on Interconnection of Sewage System in Bao'an Area of Maozhou River Basin
Aiming at the problems of weak security and low security degree of the"sewage treatment plant(STP)","sewage network(SN)"and"STP-SN"of the urban sewage system,the water quantity is calculated from the perspective of total sewage balance by taking the whole basin as a unit.Taking advantage of the hub pumping station transformation,and combining the modes of gravity flow,one-way pressure flow,two-way pressure flow,and etc.,the"upstream,midstream,downstream"interconnection and unified scheduling of the sewage system in the basin is successfully realized,thus to improve the emergency support capability of the sewage system,reduce pollutant overflow,and build a safe,reliable,resilient,efficient,environmentally friendly,and gray-green urban sewage system,which provides the Shenzhen paradigm for the construction of a sustainable sewage system in megacities.
