Abstract

Abstract

This paper studied the anaerobic startup of pomace liquid waste anaerobic process with high concentration of VFA through experiment， and four conditions should be met during the startup of anaerobic reaction． The results showed that the startup process could be divided into four stages according to the startup process． Organic acid accumulation could be detected before the indictors，like pH etc，changed notably，through the calculational analysis by track the organic carbon balance of the anaerobic in the experiment． By using the urea to control the acid-base balance of digestive juice，the organic load and the gas production was 2. 83 kg /( m3·d) and 658. 8 L/( m3·d) respectively，as the anaerobic startup process reached a stable operation．
