本文通过污泥引种的方式,将有效微生物(天意EM原露)投入装有驯化成熟后污泥和校区生活污水的SBR反应装置中,对校区生活污水处理进行了初步研究。实验结果表明:在常温下(18℃~25℃),控制pH在7.0~8.0,EM菌(天意)在SBR反应器内对COD、总磷、总氮的去除均有一定的促进作用,最高去除率分别达92.08%,76.96%,81.87%。在同一运行条件下配对的EM菌(天意)的3个投药量1/1000,3/1000,5/1000,进行对比实验,确定EM菌(天意)在SBR反应器中对校区污水处理的最佳投药量为3/10000~5/1000;在以日为周期的运行处理过程中,对照组的最短达标排放时间是8h, EM菌(天意)投菌组的最短达标排放时间是6h。

This article way which introduces a fine variety through the sludge, after (the divine intervention EM original dew) invests the effective microorganism is loaded with domesticates the mature sludge and in the school area sanitary sewage SBR response installment, has conducted the preliminary study to school area sanitary sewage processing. The experimental result indicated that, Under the normal temperature 18 ℃ ~ 25 ℃), controls pH 7.0 --8.0, the EM fungus (divine intervention) in the SBR reactor to COD, the total phosphorus, the total nitrogen removes has the certain promoter action, high removeing rate distinction 92.08%, 76.96%, 81.87%. EM fungus pairs which under the identical movement condition (divine intervention) 3 throw dose 1/1,000 --3 /1,000 _5/1,000, carries on the contrast experiment, determined the EM fungus (divine intervention) best throws the dose in the SBR reactor to the school area sewage treatment 3/10,000---5/1,000; In take the date as in the cyclical movement treating processes, the comparison group short reaches the sign to discharge the time is 8h _ the EM fungus (divine intervention) throws the fungus group short to reach the sign to discharge the time is 6h .
