【摘要】：青霉素發(fā)酵廢液經低溫處理后可達到廢水回用的標準。本文將青霉素發(fā)酵廢液作為拌和水用于混凝土的制備,通過試驗研究,測試了其對水泥標準稠度用水量、凝結時間和膠砂強度的影響,以及廢水的不同摻入量對C30混凝土各強度的影響。研究表明:青霉素發(fā)酵廢液對水泥的標準稠度用水量、凝結時間、砂漿的抗折和抗壓強度稍有影響;制備水泥混凝土時,加入適量的青霉素發(fā)酵廢液對混凝土的立方體抗壓強度有一定的提高;但拌和水中廢液的加入對混凝土的抗折強度有不同程度的降低�？傊�,青霉素發(fā)酵廢液經科學處理后,可替代或部分替代普通自來水作為拌和水用于制備水泥混凝土。
[Abstract]:The waste liquid of penicillin fermentation can reach the standard of wastewater reuse after low temperature treatment. In this paper, penicillin fermentation waste liquid was used as mixing water to prepare concrete. The effects of penicillin fermentation waste liquid on cement standard consistency water consumption, setting time and cement sand strength were tested. And the influence of different amount of waste water on the strength of C 30 concrete. The results showed that the standard consistency, setting time, flexural and compressive strength of mortar were slightly affected by penicillin fermentation waste liquid. When the cement concrete is prepared, the cube compressive strength of the concrete is improved by adding the appropriate amount of penicillin fermentation waste liquid, but the flexural strength of the concrete is decreased by adding the waste liquid in the mixing water. In a word, after scientific treatment of penicillin fermentation waste liquid, it can substitute or partly replace ordinary tap water as mixing water to prepare cement concrete.
