3.6-1汽车注塑内饰件生产工艺流程和产污节点图
工艺流程说明:
注塑成型:首先将外购的塑料粒子利用烘料机进行混合干燥(电加热,干燥温度为80℃),然后通过真空泵投入注塑机,注塑机通过电加热至180~280℃,然后通过注射装置将熔料输送至模具内,熔料在模具内通过循环冷却水间接冷却成型。脱模后得到塑料件本体,对冷却成型后的塑料件进行检验,合格塑料件进入下一步工序,不合格品利用机旁粉碎机粉碎后返回注塑成型工序。根据产品质量决定是否修边,修饰下的塑料边角料全部回收使用,修边完毕后进行包装出厂。
粉碎:为便于注塑成型工段中回用废塑料的迅速软化,利用粉碎机将检验工段中产生的不合格品进行简单破碎,设备破碎时在废气出口配备布袋回收粉尘,减少粉尘的污染。
2、装配生产工艺流程及简述
由一期调配而来的手装装配线生产主要流程为将外购小件与生产的保险杠等组合,主要为手工的螺丝螺帽组装。产生少量外购件包装(S03)约1t/a

3.7 项目变动情况

根据现场勘察,项目生产工艺、规模等均和环评报告及批复资料保持一致,项目平面布局发生进行了优化调整(将注塑区和装配区集中进行布置等),注塑机设备数量由20台调整为17台,但注塑产能不变,不属于重大变更。

环境保护措施

4.1 污染治理、处置措施

1、废水
(1)拖把水:项目主要为注塑工序和成品的暂存,地面仅做简单的拖地,不冲洗。由于该部分水较少且不含油,因此,经沉砂池处理后和生活污水一并处理。
(2)厕所用水:通过初沉池沉淀后进入生化池进行处理。
(3)生活污水:项目食堂、浴室废水依托一期的生化池处理后排入市政污水管网进入园区(东城)污水处理厂处理;产生于项目厂房的生活污水采用生化池处理后排入市政污水管网进入园区(东城)污水处理厂处理。
(4)冷却水:项目冷却塔排为清洁下水经雨水管线排放。
2、废气
项目注塑车间静音粉碎机会产生少量粉尘,设备破碎时在废气出口配备布袋回收粉尘,减少粉尘的污染。
项目注塑工序产生少量的热塑性废气,废气由厂房机械排风系统排入厂外,对车间内和车间外的空气环境影响较小。
3、噪声
项目将注塑机和粉碎机集中布置于厂房中部并对粉碎机进行减震处理,空压机及冷却塔采用机身全封闭式,配备隔音装置,噪声经绿化带隔声处理后厂界噪声可满足《工业企业厂界环境噪声排放标准》(GB12348-2008)中的3类标准。
4、固废
项目营运期主要的固体废弃物为一般工业固废、生活垃圾、污泥。
(1)一般工业固废
项目营运期一般工业固废为注塑次品等废塑料,全部回用于注塑工序;装配包装废料由物资公司回收,不会对环境产生影响。
(2)生活垃圾
生活垃圾由环卫部门统一清运至城市垃圾处理场处理。
(3)废水处理设施
生活污水处理设施污泥由环卫部门统一清运至城市垃圾处理场处理。
(4)食堂垃圾
食堂依托于一期工程,但是由于就餐人数的增加,预计将新增餐厨垃圾经有盖塑料桶合理收集后交由供应单位处理。
采取以上固体废弃物污染防治措施后,项目营运期所产生的固体废弃物污染对外环境不会产生明显影响。

扩建项目的建设是符合铜梁区总体规划,符合铜梁工业园区的规划、产业定位,属于铜梁工业园区的主要发展产业,符合《重庆市工业项目环境准入规定(修订)》。项目选址具有良好的区位优势,电力供应充足;交通便捷;所在区域有一定的环境容量。项目建成后采取有效的污染治理措施后对外环境影响较小,从环境保护的角度看,本项目选址是合理的。
3、项目所处环境功能区、环境质量现状及存在的主要环境问题
扩建项目所在地大气环境中的SO2、NO2、PM10均满足《环境空气质量标准》(GB3095-2012)二级标准限值,均小于100%,非甲烷总烃满足相应的标准限值要求。项目所在区域环境空气质量较好,有一定的环境容量。因此,区域环境均适宜本项目的建设。本项目周边主要为机加类工业企业,无对环境有较大污染的项目。
4、自然环境概况及环境敏感目标调查
扩建项目位于重庆市铜梁工业园区,用地周围主要为工业企业,项目占地不属于基本农田,场区内无自然保护区、生态农业示范园、重点文物保护单位和饮用水源保护区,未发现珍稀动植物和矿产资源。项目东侧紧邻金地大道重庆DSI变速箱制造有限公司;东南面为重庆塞维药业有限公司;东南约2500m处为全德镇、约2600m处为全德小学;南面依次为重庆欣禧汽车零部件有限公司、重庆顺宏机械有限公司、重庆远东工业泵制造机械制造有限公司、重庆百乐维克兽药有限公司;西面依次为重庆超安机械配件有限公司、重庆龙腾钟表有限公司、重庆俊峰仪器制造有限公司、西面约1500m处为姜家岩社区;西南面约1500m处为铁佛寺;西北面约1600m处为新兴小学。扩建项目产生的污水的受纳水体为淮远河,距离扩建项目最近距离约1300m。

5、营运期环境保护措施及环境影响
(1)废气                   
项目注塑工序产生少量的热塑性废气,主要污染物为非甲烷总烃, 注塑成型温度为180℃~250℃,而PP塑料的分解温度280℃~320℃,注塑成型温度小于PP塑料的分解温度,注塑机加热不造成塑料分解,该工序主要废气污染物为非甲烷总烃。废气由厂房机械排风系统排入厂外,对车间内和车间外的空气环境影响较小。
大气环境防护距离
扩建项目根据《环境影响评价技术导则——大气环境》(HJ2.2-2008)的有关规定,为保护人群健康,减少正常排放条件下大气污染物对项目所在区域的环境影响,在项目厂界以外设置的环境保护距离。
根据环境保护部环境工程评估中心环境质量模拟重点实验室发布的大气环境防护距离标准计算程序进行计算。
计算结果:无超标点。
扩建项目无组织排放的污染物对厂界的影响浓度均满足厂界标准限值,对所在区域大气环境的影响浓度也满足标准限值,未出现超标现象,表明扩建项目无组织排放的非甲烷总烃对周围环境的影响较小,在厂界外可不设置大气环境防护距离。
(2)废水
项目主要为注塑工序和成品的暂存,地面仅做简单的拖地,不冲洗。由于该部分水较少且不含油,因此,考虑计入生活污水一并处理。扩建项目生活污水排放量为23.75m3/d,其中产生于食堂、浴室的14.35m3/d依托一期的生化池处理后排入市政污水管网进入园区(东城)污水处理厂处理;产生于厂房的9.4m3/d拟采用生化池处理生活污水处理后排入市政污水管网进入园区(东城)污水处理厂处理。
①一期工程生活污水处理设施的建设情况及其可依托性
一期污水处理设施设计处理能力为50m3/d,目前实际处理一期的生活污水为25.99m3/d,根据《重庆市森迈汽车配件有限公司(一期)建设项目竣工环境保护验收报告》(渝环(监)〔2013〕验C-03号),项目的废水能实现达标排放;本次需要依托一期处理的生活污水为产生于食堂、浴室的14.35m3/d,水质与一期现处理的水质复杂程度相同,且现在园区(东城)污水处理厂已经建成投运,项目所在区域的截污管网均已建成,园区(东城)污水处理厂的进水水质要求接近于《污水综合排放标准》(GB8978-1996)中三级标准,从目前一期生活污水处理设施运行处理效果来看,依托部分废水处理后能满足园区(东城)污水处理厂的进水要求。
因此,可依托性强也不需要增加管网等设施建设。
②生活污水对环境的影响预测及评价
扩建项目已经建成生活污水处理设施,设计处理能力为20m3/d,根据规划需要在二期处理的生活污水仅为9.4m3/d。地面仅做简单的拖地,不冲洗,产生废水较少且不含油,水质成分简单与生活污水水质接近,沉砂处理后与生活污水一并处理通过园区(东城)污水管网进入园区(东城)污水处理厂处理,园区(东城)污水处理厂处理达《城镇污水处理厂污染物排放标准》一级B标后排放。
③冷却水
冷却塔排水8m3/d,为清洁下水经雨水管线排放。
通过采取以上治理措施,扩建项目营运期产生的污废水不会对周边水环境造成较大的影响。
(3)噪声
注塑机和粉碎机的噪声值较小,考虑将注塑机和粉碎机集中布置于厂房中部并对粉碎机进行减震处理再通过厂房隔声实现噪声的衰减,空压机及冷却塔噪声经隔声处理,厂界已建成绿化隔离带。
经上述措施处理后厂界噪声可满足《工业企业厂界环境噪声排放标准》(GB12348-2008)中的3类标准。
(4)固废
扩建项目营运期主要的固体废弃物为一般工业固废、生活垃圾、污泥。
①一般工业固废
扩建项目营运期一般工业固废为注塑次品等废塑料,全部回用于注塑工序;装配包装废料由物资公司回收,不会对环境产生影响。
②生活垃圾
生活垃圾由环卫部门统一清运至城市垃圾处理场处理。
③废水处理设施
生活污水处理设施,生活污水污泥由环卫部门统一清运至城市垃圾处理场处理。
④食堂垃圾
食堂依托于一期工程,但是由于就餐人数的增加,预计将新增餐厨垃圾经有盖塑料桶合理收集后交由供应单位处理。
采取以上固体废弃物污染防治措施后,项目营运期所产生的固体废弃物污染对外环境不会产生明显影响。
6、清洁生产与循环经济
扩建项目采用了先进的工艺技术和生产设备,且在整个工艺流程中考虑了能量的利用,尽可能的降低能耗,对生产过程中产生的“三废”尽量回收利用,同时注重生产全过程污染控制,既节约了资源,控制了物料流失,又大大地减少了外排污染物对环境的影响,扩建项目清洁生产水平和达国内先进水平。
    7、环境风险评价与防范措施
依据本项目物质危险性分析和功能单元重大危险源辨识,扩建项目不存在重大危险源,且本项目周边主要为工业企业,不存在环境敏感区域,因此按二级评价标准进行环境风险评价。扩建项目涉及的危险物料种类较少,其使用量和储存量较少,不构成重大危险源,可能发生的风险事故单一。一旦发生风险事故,只要严格采取上述风险防范措施,并及时启动应急预案,能有效减轻对周围环境及人群造成的伤
害和环境危害,其风险水平可接受。。
    8、公众参与
为了提高环评工作的科学性和公正性,反映社会公众的意见,本评价通过公众参与调查,较广泛地征求了广大公众意见,并将其结果作为本次环评工作的重要参考。
公众参与采取发放问卷式调查表和公示的形式进行,主要采取现场公示。
2015年7月23日~8月7日在扩建项目周边进行第一次现场公示;2015年8月21日~9月8日进行了第二次现场公示,2015年8月18日完成后进行问卷调查。公示期间无反对和其他意见反馈。
根据公众参与调查结果显示,群众对于本项目的态度是积极的,赞成其建设并认为本项目的建设对带动当地经济发展有积极作用。评价及时向建设方反馈了公众参与调查结果,为了很好地将公众的合理建议和意见贯彻到工程建设中,要求建设方严格执行环评提出的污染防治措施,同时加强管理。营运期做好废气、废水、固体废物的污染防治工作,必须按环评提出的要求严格执行,以减少对环境的影响。
    9、总量控制
依据 “十二五”期间国家环保总局确定的污染物总量控制指标,再考虑扩建项目污染特征因子,确定扩建项目总量控制因子:COD、氨氮。
按照一级B标:生活污水废水量:0.71万m3/a,COD0.42t/a,氨氮0.06t/a。,扩建项目营运期污染物的排放应严格按照《国务院办公厅关于进一步推进排污权交易有偿使用和交易试点工作的指导意见》(国办发【2014】38号)、《关于印发重庆市进一步推进排污权(污水、废气、垃圾)有偿使用和交易工作实施方案的通知》(渝府办发〔2014〕178号)和《重庆市排污权(污水、废气、垃圾)有偿使用和交易工作实施细则(试行)》(征求意见稿)中相应要求进行合法交易并取得相应的排污权。
    10、选址合理性、平面布置合理性
扩建项目总平面布局充分结合了场地地形地貌,同时遵循了“生态、环保、节能”的设计原则,因地制宜,力求功能完备, 场内布置合理。
从物流配送角度来看,厂区内修建一条南北道路直接连通大门和1#生产厂房和2#生产厂房分别布置于该道路两侧,方便物资配送和运输。
扩建项目在采取了相应的污染治理措施后对周边环境的影响较小,环境是可以接受的。因此,从环境保护的角度看,本项目选址是合理的。
因此,从环保的角度而言,本项目的平面及功能布局设置较为合理。
    11、环境监测与管理
根据《建设项目竣工环境保护验收管理办法》和污染物排放申报管理规定,项目建成投入运行半年后应通过环境保护验收监测。具体的监测工作可委托当地法定环境监测机构进行,本项目可不设专门监测部门。
根据国家环保总局《关于开展排放口规范化整治工作的通知》(环发[1999]24号)以及重庆市环保局《重庆市排放污染物许可证管理办法》(渝环发[2001]559号)中《排污口规范化整治方案》要求对排污口进行规整。
    12环境影响经济损益分析
扩建项目的效益与环保费用之比大于1,表明本项目的环保措施在经济上是合理的。
该建设项目建成后,按正常产量测算,均可实现销售收入约1000万元,该建设项目具有一定的社会效益及经济效益。该建设项目建成后,将有效推动当地经济发展,增加就业人员经济收入,减轻社会负担,对改善人们生活有一定的积极作用。
综上所述,扩建项目建成后,污染物排放会对周围环境带来一定的影响,但本项目对全厂污染物排放得到有效的控制,减轻了对环境的污染,在获取较好的社会经济效益的同时环境效益亦十分明显。
    13综合结论
综上所述,扩建项目有明显的社会经济效益;扩建项目符合国家产业政策,符合铜梁区总体规划,符合铜梁工业园区的规划、产业定位,符合《重庆市工业项目环境准入规定(修订)》。项目采用了先进的设备,符合清洁生产要求,所采用的污染防治措施技术经济可行,项目严格按照评价提出的污染防治措施后,排放的污染物对周围环境影响较小,可将环境风险影响降至最小程度。因此,从环境保护角度分析,扩建项目建设是可行的。
二、评价反馈和建议
(1)在工程实施过程中,考虑在全厂全面推行清洁生产审计,进一步提高企业清洁生产水平。
(2)加强员工环保知识的培训和教育,提高员工环保意识,具备及时处理异常事故发生的应对能力。

10  验收结论与建议

10.1项目概况

重庆森迈汽车配件有限公司位于重庆市铜梁工业园区金地大道9号,于2011年开始在重庆市铜梁工业园区金地大道9号建设一期年产12万套汽车配件生产项目,2011年8月13日,铜梁县环境保护局以《重庆市建设项目环境保护批准书》(渝(铜)环准〔2011〕14号)文件批准了该项目的建设。2013年10月铜梁县环境监测站编制完成了《重庆市森迈汽车配件有限公司(一期)建设项目竣工环境保护验收报告》(渝环(监)〔2013〕验C-03号),认定重庆市森迈汽车配件有限公司污染物达标排放,达到竣工验收条件。

10.2环保措施落实情况

1、废气治理措施
项目注塑车间静音粉碎机会产生少量粉尘,设备破碎时在废气出口配备布袋回收粉尘,减少粉尘的污染。
项目注塑工序产生少量的热塑性废气,注塑成型温度为180℃~250℃,而PP塑料的分解温度280℃~320℃,注塑成型温度小于PP塑料的分解温度,注塑机加热不造成塑料分解,该工序主要废气污染物为非甲烷总烃。废气由厂房机械排风系统排入厂外,对车间内和车间外的空气环境影响较小。
2、污废水产生及治理措施
项目主要为注塑工序和成品的暂存,地面仅做简单的拖地,不冲洗。由于该部分水较少且不含油,因此,经沉砂池处理后和生活污水一并处理。项目食堂、浴室废水依托一期的生化池处理后排入市政污水管网进入园区(东城)污水处理厂处理;产生于项目厂房的生活污水采用生化池处理后排入市政污水管网进入园区(东城)污水处理厂处理;项目冷却塔排水为清洁下水经雨水管线排放。 
3、噪声治理措施
项目将注塑机和粉碎机集中布置于厂房中部并对粉碎机进行减震处理,空压机及冷却塔采用机身全封闭式,配备隔音装置,噪声经绿化带隔声处理后厂界噪声可满足《工业企业厂界环境噪声排放标准》(GB12348-2008)中的3类标准。
4、固体治理措施
项目营运期主要的固体废弃物为一般工业固废、生活垃圾、污泥。
(1)一般工业固废
项目营运期一般工业固废为注塑次品等废塑料,全部回用于注塑工序;装配包装废料由物资公司回收,不会对环境产生影响。
(2)生活垃圾
生活垃圾由环卫部门统一清运至城市垃圾处理场处理。
(3)废水处理设施
生活污水处理设施污泥由环卫部门统一清运至城市垃圾处理场处理。
(4)食堂垃圾
食堂依托于一期工程,但是由于就餐人数的增加,预计将新增餐厨垃圾经有盖塑料桶合理收集后交由供应单位处理。
结合本次竣工验收现场踏勘及走访环保部门了解情况,工程运行期各项防治措施有效,满足竣工验收要求。
