Environment Status
Water Environment
Status
The quality of drinking water source in Tianjin kept good, and during Luan River Diversion and Huang River Diversion, the results of 27 national assessing indicators all met with Grade Ⅲ of surface water standard, The qualified percentage of urban centralized drinking water quality has been keeping 100% in recent 9 years;
The water quality of rivers for sight, such as Hai River, has arrived at the corresponding functional water quality standard;
The water quality of sections under national control has no obvious change;
The water quality in coastal area decreased a slightly.
Major Pollutants Discharge
The total wastewater discharge was 681.95million tons, among it, 196, 8 million ton from industrial wastewater, 485,16 million tons from domestic sewage.
The total discharge of COD was 132,000 tons, among of which 22,217 tons was from industrial wastewater, 109,8 tons from domestic sewage.
Measures and Actions
Strengthened the protection of drinking water source. Carried out the instruction of Premier Wen and researched on the mechanism of inter-province ecological compensation in the entire river basin of Luan River Diversion water source. Cleaned up potential risks of drinking water around Yixingfu waterworks gradually. Monitored the water flowed into Yuquao Reservoir. Made environmentalsafetyassessment to the courses of Yellow River diversion, so as to make a policy support to the diversion of water from the Yellow River to Tianjin for the government. Made plans for the environmental protection of Yellow River diversion and ensured the safety of drinking water to the urban residents. Researched on the state of village drinking water source.
Improved surface water protection and management. Carried out river patrolling of landscape water in the central city actively, analyzed the water quality and promoted a new 3 year WaterEnvironmental Treatment action. Adjusted the monitoring sections of surface water.
Prompted to carry out the implementation of Water Pollution Prevention and Control Plan of Haihe River Basin Gave full play to tied mechanism of departments to propel programming Projects. Passed the check of implementation status of planning in 2009.Carried the spirit of” Inter-Ministerial Joint Conference and special meeting of water pollution prevention and control in Haihe River Basin.
Tightened the control of key industries and pollutants. Identified the key Water Pollution resources list through the state of Key Supervision enterprises, such as close down, suspend operation, merge with others or shift and optimized them. Strictly implemented the “Wastewater Integrated Discharge Standard in Tianjin” to promote enterprises to meet the discharge standard. Carried out survey and evaluation to heavy metal pollution database and compiled “enforcement Program on heavy metal contamination in Tianjin”. Researched on the state of sewage treatment of key industries.
Further intensified supervision on wastewater treatment plants. Standardized the management of sewage treatment plant in the city by the following 4 steps: creating archives, intensifying responsibilities of enterprise as well as management and monitoring.
Thinned the environmental supervision of offshore marine areas, adjusted the environmental function zoning programme of the offshore marine areas and investigated the drain outlet into Sea.
Atmospheric Environment
Status
In 2010, 308 days met Grade national air quality standard or above, accounting for 88.0% of the total monitored days. 38 days met GradeⅠstandard and 57 days met grade Ⅲ standard. Inhalable particulate (PM10) was primary pollutant of affecting air quality.
Major Pollutants Emission
The emission of SO2 was 235, 200 tons, among which 217, 600 tons were from industries .The emission of smoke was 64.6 thousand tons, among which 53, 800 tons from industrial sources. The industrial dust was 8 thousand tons.
Measures and Actions
Strengthened the control of coal burning pollution to decrease SO2 . 10 desulfurization projects of coal burning boilers in power plants have been completed. 3 coal fired units were closed and 24 technical reconstruction projects were fulfilled for dust removal and desulfurization of coal burning boilers with the capacity of 10 tons per hour or above. The environmental protection departments carried out special inspection on coal-burning heating boilers in the heating period and 11 enterprises that fail to meet the requirements for pollutant discharge were placed on file for investigation and prosecution. They also announced the results to the municipal or district government.
Prevented and control construction dust. Established the Mechanism of dust prevention, implemented the Supervision on departments or district governments fully. Tianjin environmental protection bureau joined with Construction and Transportation Committee, municipal Amenities & Landscape Architecture Committee and the Land and Housing Management Bureau carried out a specialaction to inspect construction sites including buildings, roads and bridges, housebreaking and so on. Self-checking of dust control was also developed between district governments, and the 387 scavenger’s carts and 158 sprinklers had greatly cleaned the road. Hence all kinds of dust were under effectivecontrol.
Strengthened the control of vehicle emission. Issued signs for those automobiles going to Beijing and 180,000 environmental signs were issued. Carried out vehicles replacement coordinated with the municipal Committee of Commerce and the Finance Bureau. Till the end of 2010, 10500 cars had gone through the formalities and 50, 000,000 YUAN national subsidy has been input. The municipal environmental protection bureau in conjunction with the municipal public security bureau was preparing to issue environmental protection symbols.
Acoustic Environment
Status
The environmental acoustic quality maintained stable. The main noise affecting urban acoustic environmental quality was from human activies and transportation.
The average noise level in urban area was 54.6db (A), 0.1db (A) lower than 2009. The acoustic grade was Grade II. The environmental noise sources order according to the covering area were as follows: 65.9% from human activities noise, 22.4% from transportation, 11.2% from industries and 0.5% from construction sites. The average traffic noise level was 67.7db (A), the same as the last year, with Grade I of acoustic environmental quality.
Measures and Actions
Developed the established Quiet Residential Areas. 26 Quiet Residential Areas were established in 2010. Up to now, there were 237 Residential Areas given the title of Quiet Residential Area, accounting for 14.8% of property management areas. Residential environment has been improved greatly with this action. Strengthened the regular inspection on fixed noise sources, strictly enforced construction declaration and notice system. Organized night inspection on construction sites. Develop the noise prevention action during the entrance examination to high school and college, and efficiently controlled noise. During the exam, environmental protection department has coordinated with transport management, 120 first-aid center, air force and railway office to send law enforment officers to monitor around the exam spot to make sure the exam moving well. The regional divisions applying to National Standards for Acoustic EnvironmentalQuality were readjusted. The traffic noise was effectivelycontrolled through broadening the road and tooting forbidden actions.
