摘要:赵庄煤层气井水中富集产甲烷菌群,可优化产气能力。采用厌氧富集得到本源菌群,通过正交试验优化产气条件。水样中存在产甲烷菌群,实验室条件下最优产气条件:NH,Cl为1.0g/L, K,HPO4为1.5g/L,MgCl为0.1g/L,煤粉添加量160g/L,60d产甲烷量达18.07%。赵庄井田产甲
烷菌群通过富集可以降解无烟煤产气,通过条件优化可提高其降解无烟煤产气的能力。关键词:生物产气;赵庄井田;产甲烷菌群;营养组分;条件优化

Abstract: There exists methanogenic bacteria in the water of Zhaozhuang coal seam gas well,and its gas production capacity can be op-timized. The original bacteria group was obtained by anaerobic enrichment,and the eonditions of gas production were optimized by or-thogonal test, Methanogenic bacteria existed in water samples, Under the laboratory conditions, the optimum biogas production conditions were NH, CI:1. 0 g/L,K, HPO, :1. 5 g/L,MgCl, :0. 1 g/L, and the amount of coal powder added was 160 g/L, The methane yield of 60 d was 18. 07% , The acumulation of native bacteria can make use of anthracite to produce methane, and the gas yield can be improved by optimization.
Keywords:biogenic coal bed methane;Zhaozhuang Mining Area; methane producing bacteria group; nutritional components; condition optimization

引言
煤层气(CoalBedMethane,CBM)是储存在煤层
中、自发产生的一种非常规天然气,其主要成分为甲烷,并含有少量的CO、CO2、Nz、H,S、H等气体,以吸附态为主、游离态为辅,储存在煤层基质表面或空隙中,是一种非常优质的清洁能源。煤层气开发利用被列入国家能源局十三五规划,其产业化发展
可增加清洁能源的供应,保障煤矿安全生产,减少大气污染和降低温室效应[2]。
赵庄井田位于沁水盆地中段东部,海河水系浊漳河流域和黄河水系丹河流域的分水岭地带,北部为长治盆地,南部为高平一晋城盆地,中西部由丘陵中山组成,海拔+800~+1300m。赵庄井田低软松渗、构造复杂,煤层气地面抽采效果并不理想,井下抽采投资大效果差,严重影响煤矿采掘进度及安全生产。微
