BIM技术在江夏污水处理厂中的应用
The Application of BIM Technology in Jiangxia Sewage Treatment Plant
一、项目简介
1. Introduction
武汉水资源丰富，也面临洪涝灾害及水体污染问题。通过地图显示在武汉主城区南侧是污水治理空白区域。江夏污水厂的建设正是为填补这一空白。
Although rich in water resources, Wuhan faces the problems of flood and water pollution. The map shows that there is no sewage treatment plant on the south side of Wuhan main urban area. Therefore, Jiangxia Sewage Treatment Plant is built to fill this gap.
江夏污水厂选址西临青郑高速，东临白沙洲大道，沿臣子山北部延伸为带状，并在西北角与青菱湖相接。规划分三期建设，本项目为一期工程。
Jiangxia Sewage Treatment Plant is bordered by Qingdao-Zhengzhou Expressway in the West and Baishazhou Boulevard in the east. It is ribbon-shaped along the northern part of Chenzi Mountain and is connected with Qingling Lake in the northwest corner. The plan is divided into three construction phases, and this project is Phase I.
污水厂设计规模为15万吨/天，投资约6000万美元。出水水质达到一级A标准。污水厂二级处理采用改良A2O加二沉池工艺，深度处理采用高效澄清池加纤维转盘滤池工艺，出水采用二氧化氯消毒工艺。污泥处理工艺采用重力浓缩至98%，然后机械深度脱水至60%。项目单体众多，复杂度高，非常适合BIM技术的应用。
The treatment capacity of this plant is designed to be 150,000 tons per day, with an investment of USD 60 million. The effluent quality meets A-grade standard. The secondary treatment step adopts the improved A2O + clarification technology, the advanced treatment step adopts the high-efficiency clarifier + fiber rotary plate filter technology, and the effluent is disinfected with chlorine dioxide. The sewage treatment technology uses 98% gravity concentration, and then 60% mechanical deep dehydration. This project involves plenty of monomers and is very complexed, very suitable to apply BIM technology.
项目在规划与方案设计，深化设计，施工和运营阶段运用多款软件，开展了20余项BIM应用。
More than 20 BIM applications have been adopted during the overall plan design, detailed design, construction and operation process.

Different professions inspected design problems of each other through interference and coordination in single part design. After the structure design was completed, necessary materials were provided for the structure model drawing. Technology professionals copied the structure view to provide materials and express it in drawing according to the designed technology model.
