包頭市金蒙稀土有限責任公司成立于2000年8月，占地面積兩萬六千多平方米，公司現有稀土精礦焙燒回轉窯、稀土萃取分離線、稀土氧化灼燒，涉及稀土加工的不同層次。公司各生產線布局合理、工藝先進、銜接流暢、相互配套、自成體系。產品包括稀土分離產品的各種鹽類和氧化物等十余種。公司主要大氣污染物有二氧化硫、氮氧化物、硫酸霧、氟化物、顆粒物等主要污染物。在建廠初期按照國建污染物排放標準我公司已建立的相應的大氣污染物處理設施，從2001年至今針對大氣污染物治理設施進行了多次的改造。2020年1月開始所有有色冶煉行業全部執行了特別排放標準，為了保質保量的達到污染物排放標準，我公司于2019年開始針對脫硫設施、除塵設施、噴淋系統進行了升級改造，并且將脫硫設施、及噴淋設施進行了整體的拆除改造，改造過程中投資自籌資金300萬元左右，每噸氧化物成本提高60元左右，改造后完全可以達到大氣污染物特別排放標準。

二、      監測方案的調整變化情況

按照《稀土工業污染物排放標準》《鍋爐大氣污染物排放標準》《惡臭污染物排放標準》中要求，開展二氧化硫、氮氧化物、顆粒物、硫酸霧、氯化氫、氟化物、無組織氨氣、林格曼黑度等污染物的監測。

三、      監測情況

廢氣和環境空氣監測內容見表2。

表2  廢氣和環境空氣監測情況一覽表

四.         監測結果

1.全年共監測廢氣污染物6項，包括顆粒物、氮氧化物、二氧化硫、硫酸霧、氟化物、氯化氫。

2.無組織廢氣全年共監測廢氣污染物7項，包括顆粒物、二氧化硫、氮氧化物、硫酸霧、氨、氯化氫、氟化物，每半年一次，共計2次。

3．廠界噪聲監測結果

全年共監測廠界噪聲4次，年平均監測濃度為56.8 dB（A），監測濃度最大值為60 dB（A），最小值為53.6 dB（A），達標率為100%。

五、污染物排放量情況

1．全年廢氣有組織污染物排放量

2.             產生一般工業固體廢物，廢水中和廢渣，年產14079.50噸，全部委托巨能粉煤灰利用有限責任公司處置。

3.             廢水排放量：產生的廢水經處理后全部回收利用，不外排。
