1 General Situation of the Project
1.1 Background of the Project
Dashiqiao city now owns nearly 20 heating companies, the entire area altogether has 101 heating boiler rooms in large and small scale, and 120 boilers, and the total nameplate output is 457.6MW. Among which, within the scope of the project, there are 64 heating boiler rooms, 76boilers, 407.4MW of the total nameplate output, and 17 heating enterprises, among which the biggest heating enterprise is Hongyang Thermal Energy Company.
At present, the existing problems concerning heating supply shall be as follows:
(1)within the scope of 3,470,000 square meter heating area, there exist heating boilers as many as 76, and the boilers’ aggregate capacity is 407.4 MW, the boiler capacity in unit heating area is 117.4 W/m2, and the average capacity of each boiler is only 4.85MW. From the above data, we can see, the existing boiler capacity is rather small, and boiler quantity is too many, while the heating efficiency and the equipment utilization rate are very low, the energy waste phenomenon is rather serious, the equipment gets aging, the heating quality is quite worse, the equipment for dust-removal and desulphurization is so imperfect that environment suffer froms from serious pollution.
(2)Due to the unsystematic plan, disorder development and unreasonable layout of the original pipeline network design, some part of the pipeline network has to suffer from from serious maladjusted service condition of water power and thermal energy.
(3)The pipeline network has seriously become aging, and is absent from receiving the prompt service, the replacement and transformation for a long time, which makes the system water supplement up to 2-4% of the system circulating flow, but through nearly two years maintenance and transformation ,the water loss rate of the pipeline network falls to 2.17%.
At present, the majority of constructions in the city zone of Dashiqiao all are provided the heating by the scattered boiler rooms in middle and small scale, the heating efficiency of scattered boilers is ,generally speaking, as low as 40~65%; with so many chimneys and backward dust-removing equipment, the efficiency of majorities of dust-removers falls between 60-85%, and also most of them have not yet adopted the desulphurization facilities and the pollution is serious; the intermittent heating is employed by most of the boiler rooms , which causes way too much heat wastes, the fuel consumption amounts to as many as 159,500 tons every year, the annual discharged SO2 and fly ash is respectively 1879.2 ton and 1360.5 tons, which has not only caused the serious pollution to the city environment, but also has increased the freight volume of coal, the ash, the dregs, and caused more pressure on the municipal traffic and transportation and also worsened the pollutants emissions of the transportation vehicles, moreover, it has also occupied great area of the construction land and city greenbelt, which have seriously affected the city landscape and the environment quality of Dashiqiao city.
itable choice for the urban development to construct large-scale heating source factory and the heating network and further substitute the city centralized heating for the scattered heating. After this project implementation, we may realize the centralized heating for 4,943,000 square meter floor space, and substituting the city centralized heating for the scattered coal-burning boilers may greatly save the energy and realize the goal of approximately 95,300 tons of annual coal-saving quantity, and reduce the occupying land area, dwindle the discharging volume of the mist and dust, SO2, etc. is respectively 1360.5 ton/year, 1879.2 ton/years, and simultaneously has also dwindled the freight volume of coal, dregs and also alleviated the traffic pressure and as well as reduced the automobile exhaust emissions, thus it is conducive to improving the city environment condition. At the same time, it will greatly improve the heating quality and the living standard of the local people. Simultaneously we will continue to strengthen the transformation dynamics for the original pipeline network, so as to control water loss rate of the pipeline network to be: the first level network ≤1, secondary network ≤2. Therefore, we can say that this project construction has not only the economic benefit, but also has the considerable effect and profit on the aspect of environment and society.

1.5 Substitution Source Situation
After implementation, this project will replace 64 scattered small boiler rooms in its heating scope, altogether 76boilers, with aggregate capacity483.5t/h.
These small boiler rooms can discharge soot and SO2 respectively 1360.5t, and 1879.2 t every year.
After the project implementation, these small boilers will be completely shut down, the low and short chimneys will completely demolish, which will greatly improve the ambient air quality in Dashiqiao city .
After completion and having been put into production, this project will discharge 12.3 t/a soot and 170.4t/a SO2. Since it has replaced some part of small boilers in the Dashiqiao urban district, 1360.5t/a soot and1879.2t/a SO2 will be replaced. After the implementation of this phase project, the region will be able to reduce 1347.9t/a soot and 1708.8t/a SO2.

3Analysis of the Environmental Impact
This Chapter is aiming at collecting the negative environmental impact of the project, which is mainly based on the environmental impact report of the project.
3.1 Present Situation of the Environment Quality
(1) Ambient Air Quality
From January 22nd to 26th, 2007, the monitoring results from 5 day-long continuous surveillance indicated that:
- - on 1#-7# monitoring sites, the daily average concentration scope of TSP is 0.207～1.292mg/m3, the daily average concentration on 7 monitoring sites all exceed the allowed figures, and the maximum daily average standard-exceeding multiple scope is 0.90~3.31, standard-exceeding rate is 60%~100%; Causes for exceeding the allowed figures shall be mainly attributed to the soot and fume pollution caused by the local industry and mining enterprise and boiler rooms, moreover, the exposed land and the few vegetation coverage of the local area are also the factors causing the local soot and fume pollution.
- - on 1#-7# monitoring sites, the daily average concentration scope of PM10 is 0.153～0.723mg/m3, the daily average concentration on 7 monitoring sites all exceed the allowed figures, and the maximum daily average standard-exceeding multiple scope is 1.59～3.82, the standard-exceeding rate is100%; Causes for exceeding the allowed figures shall be mainly attributed to the soot and fume pollution caused by the local industry and mining enterprise and boiler rooms, moreover, the exposed land and the few vegetation coverage of the local area are also the factors causing the local soot and fume pollution.
- - on 1#--7# monitoring sites SO2 hourly concentration scope is 0.002～0.341mg/m3, hourly concentration on 7 monitoring sites all reach the designated standard, the daily average concentration scope is 0.007～0.212mg/m3, and daily average concentration on 4 monitoring sites all exceed the allowed figures, the maximum daily average standard-exceeding multiple scope is 0.03~0.41, and the standard-exceeding rate is 20%~60%; Causes for exceeding the allowed figures shall be mainly attributed to the SO2 pollution discharged by the local boiler rooms and the peripheral enterprises.
In summary, the monitoring factors on 7 monitoring sites within the assessment-receiving region all exceed the requirements of limit value in the GradeⅡstandard in "Ambient Air Quality Standard" .
(2) Noise Environment Quality
The noise background value of the planning to choose factory site and periphery of the factory and as well as the inhabited area can satisfy the requirements of the GradeⅡstandard stipulated in "City Region Ambient Noise Standard" (GB3096-93).
