,没有集中排放的大气污染源。建成投入营运后的主要气型污染物为住户、商业餐饮油烟废气，一般油烟浓度为 2 12 mg/m3。 根据 环境影响评价技术导则 大气环境（ HJ2.2-2008） 环境保护部环境工程评估中心推荐 大气环境评价等级的确定标准计算程序计算： Pi 10%，确定大气环境评价工作等级为三级。 1.5.2 水环境影响评价内容及等级 本项目水污染源主要为居民住宅、商业等生活污水，污水排放总量为 460.2m3/d，年排放总量为 16.8 万 m3。 污水中主要污染物有 BOD5、 COD、动植物油类、 NH3-N、SS 等，污水水质复杂程度为简单，且 污水经化粪池厌氧消化处理后由污水管道再排入城市污水管网，污水将纳入长沙市 岳麓 城市污水处理厂集中处理， 根据 环境影响评价技术导则 地面水环境（ HJ/T2.3-93） ，水环境评价等级确定为三级。 1.5.3 声环境评价内容及等级 本项目噪声主要来自项目建设期的施工噪声和运营期项目配套通风、水泵等动力设备运行噪声，项目小区内声环境执行 2 类区噪声标准，交通干线一侧执行4a 类区噪声标准，根据环境影响评价技术导则 声环境（ HJ2.4-2009），声环境影响评价确 定为二级。 1.5.4 生态环境评价内容 本项目位于河西滨江星城，项目用地目前为荒地，原有建筑物已全部拆除，现已设置围挡。 施工完成后以人工绿化方式恢复植被，为城市园林生态型，以城市绿地、街道和空隙地的观赏树木和花草为主，地块的绿地率 43.31%。 根据 环境影响评价技术导则 生态影响（ HJ19-2011），生态环境影响评价 应为三级。 1.6 环境影响因素识别及评价因子 1.6.1 环境影响识别和影响因素筛选 根据房地产项目工程特点和工程污染源分析，结合评价区域的环境概况及控制保护目标，进行了区域开发工程活动环境影响的识别和环境影响因素的筛选，其结果见表 1-10 和表 1-11。 中铁·缤纷津城 B-2-2 地块 建设项目 环境影响报告书 长沙市环境科学研究所 7 表 1-10 环境影响识别 工程阶段 水质环境 景观 陆地生态 大气环境 噪声环境 社会环境 施工期 - ­ ­ ­ 使用期 + ­ +
