On February 28, 2014, Hangzhou Jiufeng Environmental Energy Co. Ltd. made the "Information Note on the Construction of Hangzhou Jiufeng Garbage Incineration Power Generation Project". Note: The note is quoted from Annex I of the "Pre-Approval Public Notice on (Hangzhou) Hangzhou Jiufeng Garbage Incineration Power Plant Project" The average annual growth rate of garbage in Hangzhou City from 2005 to 2013 was 10.7%. The total amount of garbage in Hangzhou was about 2.61 million tons in 2011, 2.8154 million tons of domestic garbage was generated in Hangzhou city area (including Xiaoshan and Yuhang) in 2012, and 3.08 million tons of domestic garbage was generated in Hangzhou city area (including Xiaoshan and Yuhang) in 2013. The pressure of garbage disposal work is getting bigger and bigger. Meanwhile, with the construction of Future Science and Technology City in Yuhang Cluster, the former Hangzhou Yuhang Jinjiang Environmental Protection Energy Co., Ltd (Cangqian) is facing relocation, and the garbage within the original disposal area is facing the danger of having nowhere to go.
According to the "Hangzhou City Master Plan", "Hangzhou Environmental Sanitation Specialized Planning" and Hangzhou Hangzhou Planning Letter No. 2013308, the Planning Bureau recommended that the new waste incineration project in the western part of Hangzhou city in accordance with the planning adjustment of the major projects to carry out site selection demonstration. According to the relevant requirements of Hangzhou Municipal Government and Hangzhou Urban Investment Group, the new waste incineration power generation project in the west is constructed. Ltd., Hangzhou Environmental Group Co., Ltd. and Hangzhou Road & Bridge Co., Ltd*** invested in the project together. The new company commissioned a unit with relevant planning preparation qualifications to prepare a project-specific planning and site selection demonstration report. in October 2013, Hangzhou City Investment Group established Hangzhou Jiufeng Environmental Energy Co., Ltd. and commissioned the Hangzhou Urban Planning and Design Institute to carry out the preparation of the site selection and site selection demonstration report of the West Hangzhou Waste Incineration Project. On the basis of the first site selection program, the planning program was prepared to clarify the nature of the land and the boundaries.
The basic principles of the building program are
(1) Under the premise of meeting the overall layout and process flow of the main production plant, try to achieve a clear functional partition, and various types of pipeline arrangement is convenient and reasonable.
(2) Reasonably determine the vertical arrangement, saving the amount of construction work.
(3) Pay attention to environmental protection, make full use of natural conditions, strengthen greening, and create a modern enterprise atmosphere.
(4) Strictly implement the current national fire, health, safety and other related technical specifications.
Taking into account the local conditions, reasonable arrangement, because the original industrial land of the site total land size of 261.3 acres, in order to ensure that the land, the need for slope management, as well as to consider the future needs of ancillary land. The total land of the project is still 261.3 mu, and the construction land of the project and related indexes are shown in the following table: Main economic and technical indexes table No. Name Unit 1 Factory land area m2 104697 2 Factory building and structure occupying area m2 38061 3 Building density % 36.4 4 Building area m2 93,500 5 Volume rate % 0.89 6 Green area m2 18417 7 Green rate % 20.00 8 Building height M 45.00 20.00 8 Building Height M 45 Master Plan
The plan determines the waste collection and disposal in the long term around the ecological balance, resource regeneration of the waste treatment model, the establishment of the corresponding waste collection and disposal system. To manage the waste from the source of waste generation, expand the comprehensive utilization rate, reduce the total amount of production, reduce the pressure of waste terminal treatment, and form a waste treatment model in which sanitary landfill, safe incineration and comprehensive utilization are complementary to each other. Therefore, waste incineration is one of the main modes of waste disposal identified in the master plan.
In addition, the new Xiaoshan waste incineration plant in the southern part of Xiaoshan city (Ploughshares Gold), the expansion of Hangzhou Green Energy Environmental Protection Power Plant (Binjiang), and the expansion of Yuhang Jinjiang Waste Incineration Plant as identified in the master plan have all been implemented. Due to the city west of the future science and technology city of new construction,, Yuhang Jinjiang waste incineration plant is facing relocation, need to be implemented in conjunction with the current site selection plan."
The location of the incineration plant was made clear in the 2013 Revision of Hangzhou City Master Plan (2001-2020) (draft program).
Specialized planning for environmental sanitation
The current Hangzhou urban domestic waste disposal sites are Hangzhou Solid Waste Disposal Company Limited (Hangzhou Tianziling Waste Disposal General Yard), Xiaoshan District Waikan Wai Six Section Waste Disposal Yard, Yuhang Jinjiang Waste Incineration Plant, Hangzhou Nengda Green Energy Company Limited (Qiaosi), Hangzhou Green Energy Environmental Protection Power Plant (Binjiang), and Hangzhou Xiaoshan Jinjiang Green Energy Co.
According to the Hangzhou urban waste disposal and treatment flow, in order to extend the landfill life of the Tianziling Waste Disposal General Field, and vigorously promote the utilization of waste incineration, the planning consideration in the Tianziling Waste Disposal General Field around the periphery or the scope of the site of the new Tianziling Waste Incineration Plant (tentative name), relocation of Hangzhou Nengda Green Energy Company Limited (Qiaosi) to the Jiangdong Industrial Park, the expansion of Hangzhou Green Energy Environmental Protection Power Plant (Binjiang), Xiaoshan District, outside the six sections of the landfill to fill the six sections of the garbage disposal site to 2010 closed, retaining other landfills and waste incineration plants. Gradually close the other towns and cities of domestic waste temporary dumps, phased construction.
The "Revision of Hangzhou Environmental Sanitation Specialized Planning (2008-2020)" is carried out on the basis of the "Hangzhou Urban Master Plan (2001-2020)", and in terms of the layout of the domestic waste disposal facilities, the "Revision of Hangzhou Environmental Sanitation Specialized Planning (2008-2020)" newly proposes to select a site in the vicinity of, or within, the Tien Tzu-Ling Waste Disposal General Site The new Tianziling waste incineration plant (tentative name), and clear relocation of Hangzhou Nengda Green Energy Co.
2013 "Environmental Health Professional Planning Revision (2008-2020) partial revision (draft program) has adjusted the collection and transportation zoning, clear location of JiuFeng incineration plant and 3000 tons of processing capacity. Road
In accordance with the service scope of the incineration plant (mainly serving the Yuhang cluster, Liangzhu cluster, West Lake District, Gongshu District), according to the geometric center of each area, selected five characteristic points as the starting point for calculating the distance between the vehicles in each area, including the Yuhang cluster of the intersection of Wenyi Road and East-West Boulevard, the Liangzhu cluster of the intersection of National Highway 104 and Liangxiang Road, Gongshu District, the intersection of Deng Yun Road and Tongyi Road, The intersection of Fengtan Road and Pingshui Road in the north of Xihu District, and the intersection of National Highway 320 and Hangfu Road in Zhijiang New Town.
The current situation of the surrounding bus lines are mainly laid along the 02 Provincial Road, and the bus stop closer to the project site is Shangkengwu Station (about 2km away from the project site), with the passage of one bus line (475 Road: Wangjiabu - Yuhang), and the original 598 Road to Lin'an via the 02 Provincial Road has been suspended, and the surrounding public transport The service level is poor. The planned extension of BRT Line 4 to Zhongtai Bus Station in the long term will make it convenient for the staff of this block to transfer to BRT and regular buses to enter the main city of Hangzhou.
After the completion of this project, according to the reasonable traffic organization, the impact of the construction and operation of the site on the surrounding road traffic facilities is within the acceptable range; as the project is still in the site selection demonstration stage, so the final project itself needs to be implemented in accordance with the next stage of the building program of the parking allocation requirements.
