地理位置xx县食品公司屠宰场厂址建设在xx县东明镇石龙头村，位于xx县城以东偏南约5公里处，其北侧有乡村道路连接209国道。xx县位于河南省西部边陲，地处豫、陕两省的结合部， 北邻灵宝，东连洛宁与栾川，南接西峡，西和西南与陕西省的洛南、丹凤、商南三县接壤, 居北纬33323423，东经1103411122 之间。中南部山地是黄河水系和长江水系的分水岭，大部分地区属黄河水系。1.2 地形地貌评价区所在的xx县东明河西村位于xx县洛河川地东部。xx境内千山起伏，万壑纵横，河流遍布， 形成了八山一水一分田的基本地貌。全县东西宽72公里，南北长92公里， 国土总面积4004平方公里，整体轮廓近似菱形。是河南省国土面积较大，人口密度较小的边远深山区和国家级扶贫开发工作重点区。xx县地势自西向东逐渐降低，西南部海拔在15002000米以上，地势高峻，是河南省地势最高的地方。东部海拔500800米，部分超过1000米，相对高度300800米，地势低缓，山岭起伏较小，山顶较为平圆。沿xx的洛河两岸，流水侵蚀严重。据现场踏勘，评价区周围地势较平坦，地域开阔，沿洛河两岸外侧是浅山区，以洛河为中心向南、北、东南、西南、东北、西北10公里后是深山狭谷，层峦叠嶂，海拔高度最高为1000米，最低为556米，而且河谷狭窄。1.3 水文气象xx县地处亚热带、北暖温带两个气候带。北部属暖温带季风气候，续建设项目所在地自然环境社会环境简况南端地处北亚热带，一年四季分明， 光照充足。由于地域辽阔，气候要素相差较大。据xx县气象局 2000年至2002年气象资料报告分析，xx县平均气温13.0，极端最高气温37.8，最低气温15.6，年日照2028.4小时，日照率46%；主导风向东北风，年平均风速为1.1米/秒；年最多降雨量606.3毫米，日最大雨量63.5毫米，年平均降雨量为565.0毫米。评价区南800米的洛河水体，是xx县境内最大河流，也是黄河水系的主要支流之一。洛河发源于陕西省洛南县洛源乡木盆沟村，从xx县徐家湾乡小河口村入xx县境，贯穿于崤山和熊耳山之间，流至xx范里镇山河口后流入洛宁县境，洛河河面的平均宽度为160余米，水足量大，在xx境内流域长112公里，境内流域面积2164平方公里，河床比降1:435，多年平均流量为40立方米/秒，年径流总量为5.29亿立方米。在洛河流域内，流域面积在100平方公里以上的支流有9条，分别有兰草河、官坡河、木桐河、潘河、横涧河、马庄河、文峪河、沙河、范里河。1.4

工艺流程简述该公司屠宰场是xx县唯一的生猪定点屠宰场，牲畜收购后，经过圈栏储备，牲畜淋洗干净后，麻电后进入屠宰车间进行屠宰，经放血、冲洗消毒，热水烫毛以脱毛，开膛后电锯分割成块，生猪（含牛、羊）肉经检疫后售出。3 项目污染因素分析3.1 大气污染因素分析本项目大气污染源主要为锅炉烟气，其污染物为烟尘和so2。烫毛和冬季采暖需要蒸汽，拟安装一台2 t/h蒸汽锅炉，型号为dzl2-8，产气量2t/h，燃煤为山西大同、陕西神木的优质无烟煤，燃煤量为300t/a。该锅炉安装陶瓷多管旋风除尘室，根据多家锅炉使用厂家的使用情况，该项目锅炉烟气中烟气和so2产生与排放浓度分别为2000mg/nm3和432mg/m3。烟气量2400nm3/h，按每天工作10小时，总烟气量720万nm3/a，燃煤量300t/a，so2产生量为1.7*300*0.613.11t/a，so2浓度为432mg/m3。燃料煤堆存应建设煤栅，以防止堆煤风蚀扬尘。净化烟气通过一根30m高烟囱排放。可满足锅炉大气污染物排放标准（gb132712001）时段二级标准要求。3.2 废水污染因素分析3.2.1 废水水量、水质特点建设单位未能提供废水水质资料，本环评类比yy市食品公司废水治理方案和yy市食品公司废水治理工程竣工验收监测报告有续建设项目工程分析关数据。该公司肉类加工生产废水主要来自圈栏冲洗、淋洗、屠宰及厂房地坪冲洗、烫毛、分割等工段。废水中含有大量血污、油脂、油块、毛、肉屑、骨屑、内脏杂物，未消化
