针对王坡井田煤层气井采出水中污染物含量低，仅CODcr超出国家一级排放标准（ GB 8978-1996）的特点，采用活性炭吸附处理，然后通过絮凝沉降迅速回收采出水中悬浮活性炭。结果表明：活性炭投加量为3 g/L、吸附时间为40 min，PAM投加量为2 mg/L，沉降时间为5 min，活性炭回收率为98.35％，处理后采出水CODcr为45.45 mg/L、SS为7 mg/L，达到国家一级排放标准（ GB 8978-1996）。
針對王坡井田煤層氣井採齣水中汙染物含量低，僅CODcr超齣國傢一級排放標準（ GB 8978-1996）的特點，採用活性炭吸附處理，然後通過絮凝沉降迅速迴收採齣水中懸浮活性炭。結果錶明：活性炭投加量為3 g/L、吸附時間為40 min，PAM投加量為2 mg/L，沉降時間為5 min，活性炭迴收率為98.35％，處理後採齣水CODcr為45.45 mg/L、SS為7 mg/L，達到國傢一級排放標準（ GB 8978-1996）。
침대왕파정전매층기정채출수중오염물함량저，부CODcr초출국가일급배방표준（ GB 8978-1996）적특점，채용활성탄흡부처리，연후통과서응침강신속회수채출수중현부활성탄。결과표명：활성탄투가량위3 g/L、흡부시간위40 min，PAM투가량위2 mg/L，침강시간위5 min，활성탄회수솔위98.35％，처리후채출수CODcr위45.45 mg/L、SS위7 mg/L，체도국가일급배방표준（ GB 8978-1996）。
The pollutant concentration of CBM well produced water is quite low , with only COD cr exceed national discharge standardⅠ( GB8978 -1996 ) .Activated carbon was used to quickly recover suspended activated carbon in produced water through flocculation and sedimentation.The results show that when the activated carbon dosage was 3 g/L, adsorption time was 40 min, PAM dosage 2 mg/L, settling time of 5 min, the activated carbon recovery rate was 98.35%, CODcr is 45.45 mg/L, SS is 7 mg/L in the produced water, meeting the national discharge standardⅠ (GB8978-1996).
