21、是来自电石库、乙炔灌装处和乙炔发生器。电石受潮会释放出乙炔，乙炔灌装处密封不好可能会有乙炔泄漏，上述乙炔均是无组织排放，由于排放量小，对周围大气环境影响不大。电石库应好防潮工作，减少电石库存量，则可以尽可能避免乙炔气体的产生。乙炔灌装工序要做好气瓶的日常检查，确保连接处的密封性，则可以避免乙炔气体的泄漏。乙炔发生工段会有不凝性气体放空，根据物料平衡表，乙炔发生工段不凝性气体为氮气，放空量为 0.5t/a，即 0.14kg/h，排放方式为间歇排放，氮气放空不会对大气环境产生不良影响。企业现购的电石多采用软包装，一般不需要破碎。为确保原料的尺寸，企业仍设有破碎机一台，用来破碎极少量的大块电石，此时
22、会产生少量破碎粉尘，采用布袋收尘后粉尘（已风化）排入电石渣池。采用全密封低压乙炔发生器是用电石桶把已破碎好的一定规格电石加入到发生器上部的电石贮料斗中。由于它采用的是全密封加料，所以在加料过程中没有任何电石粉尘产生，操作环境较好。职工食堂厨房设有 1 台燃气双灶，液化石油气为清洁能源。项目劳动定员为 56 人，就餐率按 70%计算，在烹饪过程中会产生一定量的油烟排放，餐饮油烟气可按食用耗油系数进行计算，一般食用耗油系数为 5kg/100 人次 天，食堂日耗油 2kg，烹饪过程中食油的挥发。损失按 3%计，则公司中食堂日产生油烟0.06kg，合计约 18kg/a。企业采用脱油净化器进行处理后排放

29、，经布袋收尘后不会对周围环境造成不良影响。因此，本项目完成后，在正常生产情况下对周围大气环境的影响不大。按照制定地方大气污染物排放标准的技术方法 （GB/T1320191）中的要求，对于有害气体无组织排放需计算确定一定的卫生防护距离，以保护居住区不受有害物的影响。由于未查到乙炔的相关质量标准，因此，没有判断依据，无法计算卫生防护距离。因此，本评价采用安全防护距离作为该企业的卫生防护距离，即该厂的卫生防护距离为 50 米。根据现场勘测，本项目 50m 范围内无敏感目标，故满足本项目卫生防护距离要求。32 水环境影响预测溶解乙炔生产过程会产生电石渣水，年产生电石渣水总量约为 31700t（含水 9
30、0%） ，电石渣水排入电石渣池再由电石渣泵把电石渣水打入电石渣坑内沉淀，电石渣水再经过二次沉淀后将澄清水用泵返回发生器循环使用，澄清水全部回用不外排，年回用量为 25473.53t。此外，经沉淀、压滤后的电石渣为6450.5t/a（含水 50%） 。乙炔气瓶冷却岗位会产生冷却废水，年产生量约 6.8 吨，排入乙炔冷却水收集池沉淀、冷却后回用。项目空分冷却水年产生量 10 吨，排入空分冷却水收集池沉淀、冷却后回用。净化乙炔气后剩余的废酸与废碱中和后一并排入电石渣池。企业每 2 月清洗一次设备，会产生清洗废水，年排放量约 1440 吨，清洗废水排入清洗废水收集池，脱油后供厂区绿化使用。项目生产废水
31、全部循环使用，不对外排放，因而不会对水环境产生影响。本项目投产后全厂生活污水排放量为年产生生活污水 806 吨，生活污水中污染物的浓度一般为：CODcr350mg/L，BOD 5 160mg/L，SS 180mg/L，NH 3-N30mg/L。则生活污水中污染物产生量为：CODcr 0.28t/a，BOD 50.12t/a，SS 0.14t/a，NH 3-N0.02t/a。食堂污水经格栅、隔油处理后与卫生冲洗水一起采用厌氧+ 好氧生活污水处理设施处理后达到污水综合排放标准 （GB897996）一级标准再排放，生活污水经处理后，主要污染物达标排放量为：CODcr 0.08t/a，BOD 50.0
32、03t/a，SS 0.01t/a，NH 3-N0.01t/a。生活污水在达标排放的情况下，不会对纳污水体金华江造成明显的不良影响。远期待本项目污水接入婺城is responsible for Organization training, and implementation, and check; 12, master workshops annual economic indicators of implementation, reporting to financial health on a regular basis; 13, is responsible for the daily

39、。企业要做好电石渣池的防渗工作，确保电石渣得到及时妥善处置，不得长期存储电石渣，电石渣池内的电石渣不得超过限额（一周存储量，即 150t） 。油水分离及压缩工序会产生少量废机油，约 120kg/a，属于危险固废，由企业收集后送有资质单位处置。生活垃圾按每人每天 1.0kg 计，则产生生活垃圾约 16.8t/a，生活垃圾集中收集后，交由环卫部门统一处理。在上述前提条件下，本项目固废不会对周围环境产生污染影响。35 环境风险影响预测假设乙炔钢瓶爆破点燃，产生爆燃火球，造成强辐射危害。爆破形成火球产生热辐射火灾危害结果如下：发生火球半径为 8.591m；火球持续时间为1.333s；死亡的热辐射通量为
40、.3W/m 2，死亡半径为 0m；二度烧伤的热辐射通量为.6W/m 2，二度烧伤半径为 0m；一度烧伤的热辐射通量为 55384.8W/m2，一度烧伤半径为 13.6m；财产损失的热辐射通量为 30747.1W/m2，财产损失半径为20.5m。根据金华溶解乙炔厂年产 80 万立方米乙炔生产迁建项目安全预评价报告，乙炔气瓶发生物理爆炸时，离爆炸钢瓶 0.7m 处冲击波超压使大部分人员死亡；使建筑防震钢筋混凝土破坏，小房屋倒塌。离爆炸钢瓶 1.4m 处冲击波超压使人听觉器官损伤或骨折；使建筑墙裂缝。离爆炸钢瓶 2.1m 处冲击波超压使人轻微损伤；使建筑窗框损坏。氧气瓶发生爆炸时，装置 5m 处冲击
