New sources of pollution will be subject to strict control
As a protective shield to protect the Dongjiang River water source, Dongguan Canal accepts the watershed accounted for more than 70% of Dongguan's total sewage discharge, as well as the Guanlan River in Shenzhen, Huizhou Tonghu River, about 500,000 tons of sewage. In addition, the secondary pollution of the river bottom mud, water mobility is not strong, resulting in the canal water body black and smelly, the water quality is inferior to five categories.
"The governance of the canal should focus on source governance, the most basic work is to control the new sources of pollution." The head of the city's environmental protection bureau said the environmental protection department is working on the development of the total amount of sewage control, regional restriction, industrial restriction policy measures. The environmental protection department will take regional restriction measures, where the canal upstream of the new polluting enterprises, no matter how much investment, as long as there is water pollution projects will not be approved.
The reporter learned that, according to the "Dongguan Canal Comprehensive Remediation Work Implementation Program", the comprehensive remediation of the Canal, including the interception of sewage trunk pipeline network project, the interception of sewage sub-branch pipeline network project, sewage treatment plant and comprehensive supporting works and ecological restoration project four. The four projects will be carried out in stages, is expected to be completed by the end of June 2009, the total cost is estimated to be more than 10 billion yuan. Relevant sources said that pollution control is the first task of canal management. According to the canal remediation plan, before June this year, the relevant departments will complete the first batch of 15 sewage treatment plants and supporting interception of sewage trunk pipeline network project construction, interception of sewage branch secondary pipeline network project preliminary design, water body restoration project of the feasibility study and environmental assessment work. By June next year, the sludge treatment plant, the Xiaohai River Qiaotou section of the water body restoration demonstration project, part of the main river ecological restoration of water bodies, the East Canal (urban section) pure oxygen aeration rapid black deodorization demonstration project construction, driving rain water treatment plant, medical solid waste treatment plant construction will also be completed.
Built environmental protection industrial park centralized treatment of pollution
For the existing polluting enterprises will be dealt with? The person in charge said that the environmental protection department has begun to work on the construction of environmental protection industrial park, the supporting production workshop of the polluting enterprises will be included in the park for centralized construction, centralized management, centralized pollution control.
It is understood that the Environmental Protection Bureau planning in Changping, Dalang, Changan, Humen, Shatian, Hongmei, Wang Niu Dun, Zhongtang, Ma Chung and other towns in the construction of nine environmental protection professional bases, will be 628 heavily polluting enterprises of the polluting process workshop relocated to the environmental protection professional bases, the implementation of the centralized construction, centralized treatment of pollution, centralized management, to improve the ability to control pollution. Environmental protection parks built production wastewater centralized treatment plant, sewage collection pipe network and centralized gas supply and other facilities, each production workshop sewage collection after the implementation of unified centralized treatment. At present, Ma Chung Environmental Protection Park has been approved by the provincial environmental protection bureau, entered the stage of full-scale construction, the other eight will be completed within the year approval.
Additionally, the 386 remediation retained in situ, the environmental protection department will implement round-the-clock environmental protection online monitoring and management, to avoid the occurrence of enterprise emissions and discharge behavior. At present, has completed networking monitoring 14, are installing equipment in 297.
