相同pH條件下，共同作用體系中蛋白濃度比單獨溶菌酶作用系統和單獨烷基多糖苷作(zuo)(zuo)(zuo)用(yong)系統中(zhong)(zhong)的(de)(de)(de)蛋(dan)(dan)白(bai)濃(nong)度(du)之和要高。當pH分(fen)別為(wei)4、6、8和11時，共同作(zuo)(zuo)(zuo)用(yong)系統中(zhong)(zhong)的(de)(de)(de)蛋(dan)(dan)白(bai)濃(nong)度(du)比(bi)單(dan)獨(du)溶菌酶(mei)作(zuo)(zuo)(zuo)用(yong)系統和單(dan)獨(du)烷(wan)基(ji)多糖苷作(zuo)(zuo)(zuo)用(yong)系統中(zhong)(zhong)的(de)(de)(de)蛋(dan)(dan)白(bai)濃(nong)度(du)之和分(fen)別高54.82、25.07、38.15和166.25 mg/L。說明(ming)(ming)聯(lian)合作(zuo)(zuo)(zuo)用(yong)系統的(de)(de)(de)水解效果(guo)(guo)在酸(suan)性(xing)和堿(jian)(jian)性(xing)條(tiao)件下(xia)(xia)有所提升。在酸(suan)性(xing)條(tiao)件下(xia)(xia)，濃(nong)度(du)差(cha)(cha)值(zhi)比(bi)在中(zhong)(zhong)性(xing)和弱酸(suan)堿(jian)(jian)性(xing)條(tiao)件大(da)，水解效果(guo)(guo)增強；在堿(jian)(jian)性(xing)條(tiao)件下(xia)(xia)，濃(nong)度(du)差(cha)(cha)值(zhi)提高，水解效果(guo)(guo)增強。當pH=11時，蛋(dan)(dan)白(bai)濃(nong)度(du)差(cha)(cha)值(zhi)達到大(da)，增強效果(guo)(guo)明(ming)(ming)顯(xian)。即酸(suan)性(xing)和堿(jian)(jian)性(xing)條(tiao)件下(xia)(xia)有利于促(cu)進溶菌酶(mei)和烷(wan)基(ji)多糖苷聯(lian)合作(zuo)(zuo)(zuo)用(yong)的(de)(de)(de)污泥水解溶出蛋(dan)(dan)白(bai)的(de)(de)(de)效果(guo)(guo)，在pH=11時，2h內促(cu)進效果(guo)(guo)為(wei)顯(xian)著(zhu)。

由以(yi)上結果(guo)可知，堿性條件對(dui)烷基(ji)多糖(tang)(tang)苷(gan)聯合溶菌酶催化污泥水解有促進作用(yong)，并(bing)且隨著pH的(de)增(zeng)(zeng)大，聯合作用(yong)系(xi)統對(dui)污泥的(de)水解作用(yong)增(zeng)(zeng)強(qiang)，剩余污泥系(xi)統中的(de)SCOD、多糖(tang)(tang)和(he)蛋(dan)白都隨之增(zeng)(zeng)加。當(dang)pH>11時(shi)，多糖(tang)(tang)，蛋(dan)白，SCOD的(de)增(zeng)(zeng)長幅度減緩。且當(dang)pH=11時(shi)，SCOD,多糖(tang)(tang)和(he)蛋(dan)白的(de)濃度差值達到大。綜(zong)合各項(xiang)指標確定(ding)優反應pH為11。
