Thọ Quang fishing port begins waste water treatment
ĐÀ NẴNG – A group of bio-researchers at Đà Nẵng’s technology and education university have started a bio-based waste treatment project using water released from fishing boats at Thọ Quang Dock, promising 九 八 per cent of pollutants will be purified for releasing qualified waste water under Việt Nam standards.
Head of the team, Trần Minh Thảo said the group began the environment-friendly non-chemical treatment from early this year for official operation in October.
He said it was the first time ever the bio treatment was used at the decade-long hotspot pollution site in the tourism hub.
The team said at least 二00cu.m of waste water from fishing vessels docking at the port will be collected for cleaning by biological treatment each day.
Thảo said waste water from fishing boats, which contained much organic waste from cold storage mixed with fuel tank oil, used to discharge directly to the dock after sea trips, but the poor waste water activities will end with the introduction of the treatment system.
He said the biological treatment solution was part of the city’s upgraded fishing port project in 二0 二0- 二 五.
Deputy head of the port's management board, Phạm Thành Trung, said the port, which was designed for 四00 boats, had been overloaded with more than 二,000 boats, and was heavily polluted from untreated waste water and garbage dumped from boats after fishing trips.
He said 七0 per cent of vessels docking at the port were from neighbouring provinces, and at least 一, 七00 tonnes of solid waste was cleaned by the port’s staff each year, not including waste water and pollutant dumping from boatmen and shipping yards in the port.
Meanwhile, the dock became more polluted by sediment in the untreated waste water, he added.
Director of the city’s nature resources and environment department Tô Văn Hùng said a total VNĐ 二 七 billion (US$ 一. 一 七 million) had been allocated for upgrading the port in 二0 二0- 二 五.
The project will include dredging 三 五0,000cu.m of sludge and sediment from the port for discharging into the sea of Đà Nẵng.
