提高沼气池的产气率是当前人们最关心韵一个问题。改革工艺是提高产气率需要研究的重要方面,但是其他研究也可能有助于提高沼气池的产气率。近年来,国外一些学者提出,目前的沼气池内存在死区,它约占沼气池:有效容积(发酵间)的70%。这一新见解正引起很多研究者的重视和赞同。我国对圆、小、浅水压 Increasing the gas production rate of biogas digesters is one of the issues that people are most concerned about nowadays. Reform processes are an important aspect of research that needs to be done to raise gas production rates, but other studies may also help improve biogas production rates. In recent years, some foreign scholars have proposed that there is a dead zone in the current digester, accounting for about 70% of the digester: effective volume (fermentation room). This new opinion is arousing the attention and approval of many researchers. China’s round, small, shallow pressure
