摘　　要：[目的]以排泥水泥淀物和废弃果渣为原料制取生物肥料。[方法]以水厂排泥水沉淀物、废弃果渣为培养基的主要原料,接入酵素菌,通过固体发酵,使其转化为生物肥料。[结果]试验表明,pH值在整个菌种生长繁殖过程中起决定性作用,pH值在6.8以上时,菌种无法生存和繁殖。[结论]排泥水沉淀物、废弃果渣用量对培养基的pH值影响很大。[ Objective] The research aimed to study the production of biological fertilizer with sludge water precipitate and discarded fruit marc. [ Method ] Sludge water precipitate and discarded fruit marc was taken for the main medium to breed enzyme microorganism. After solid fermentation, the culture was transformed into biological fertilizer. [ Result] The results showed that pH value was the decisive factor during the process of production and growth. When pH value was up to 6.8, enzyme microorganism could not grow and reproduce. [ Conclusion ] The amount of sludge water precipitate and discarded fruit marc had great influence on the pH value of medium.
