Sweetmeat is one of the non-staple foods and a kind of classic non-staple food. It is of great practical significance to study the treatment of candied waste-water from factories along the river basin. Take the digestible sludge from the pipe of the dewatering workshop of the sewage treatment plant and anaerobic treat the high-concentration candie waste-water in the plastic bucket. The results showed that the suspended matter concentration of waste-water decreased to 8.04 g/L and the removal rate reached 22.1% after 60 h treatment. The absorbance of waste-water decreased from 0.835 to 0.598, the color removal rate reached 32.4%, and the chroma of waste-water decreased from 500 times to 80 times, reaching the “secondary standard” of “comprehensive sewage discharge standard (GB8978-1996)”.
