高效填料塔生物反应器处理制药废水处理厂含硫臭气

The Treatment of Odor Containing Hydrogen Sulfide Released in the Wastewater of Pharmaceutical Factory by High Efficient Bio-reactor with the Packed Stuffing

采用装有特制ZX0 1型填料的生物反应器 ,对某药厂废水处理厂产生的含硫臭气进行了近 4个月的连续脱臭试验 .结果表明 :该填料塔生物反应器的最大容积负荷NV≤ 2 0 4 g/ (m3 ·h)时 ,H2 S去除率接近 1 0 0 % ,H2 S代谢产物主要以SO2 - 4为主 .采用少量含N、P等营养物的二次沉淀池出水为喷淋水 ,其最适喷淋率为 3 5 6L/ (L·d) .该填料塔有较强的抗负荷冲击能力 ,塔内阻抗低 ,无堵塞现象 ,无需经常进行反冲洗 ,可长期稳定运行 .

The removal experiment of odor containing hydrogen sulfide(H\-2S) from sewage disposal plant of pharmaceutical factory was carried out continuously by biological deodorization reactor packed with ZX01 stuffing.The results suggested that removal efficiency of hydrogen sulfide was nearly 100% and metabolism products of H\-2S was mainly composed of SO\+\{2-\}\-4,when the maximum influent load of the bio\|reactor was 204g/(m\+3·h).When effluent wastewater from second setting pit was used as spray water which containing a small quantity of nitrogen,phosphorus and other elements,the optimum volume of spray water was 3\^56L/(L·d).The bio\|reactor had stronger ability to resist shock of high concentration load.The bio\|reactor was not blocked during experiment of six months in which resistance was maintained at lower value,therefore,the bio\|reactor need not carry out a back washing frequently,and it can be operated steadily for long-term.
