Study on the preparation of multi element liquid fertilizer using restaurant garbage slurry as raw material by MBR membrane technology

摘要

There is a problem with a larger number of biogas slurry continuous emissions in the biogas slurry poor, and emissions is beyond of one time given the regularity of crop fertilization. This research introduces a production engineering that using the restaurant garbage as raw materials of biogas slurry, using MBR membrane technology for effective nutrient enrichment, by using biochemical technology to the product efficient of special multi element liquid fertilizer. Finally make the restaurant garbage harmless, reduction, recycling and maximize economic benefits come true.
