摘要:好氧發(fā)酵是市政污泥處理處置的重要工藝。常規(guī)污泥好氧發(fā)酵工藝以機械脫水的濕污泥（含水率約為80%）為原料，為調節(jié)含水率，需添加大量輔料和返混料，存在物料成本高、占地大、發(fā)酵效率低等弊端。為此,以深度脫水后的污泥為原料，采用好氧發(fā)酵處理工藝，通過優(yōu)化物料配比進行中試。以貴陽市新莊一期污水處理廠含水率在60%左右的低溫干化污泥為主要原料，添加總量約13%的輔料和返混料。發(fā)酵過程中記錄溫度和產品主要指標，結果表明，工藝改良后深度脫水污泥在大幅減少物料添加量、減小占地的情況下，可進行正常的好氧發(fā)酵，同時達到加速升溫、縮短發(fā)酵周期的效果。
Abstract:Aerobic fermentation is an important process for municipal sludge treatment and disposal. The traditional aerobic fermentation process utilizes the mechanical dewatered sludge (water content is about 80%) as the raw material, and needs to add a large number of auxiliary materials and returned mixture to regulate the water content, which leads to the problems of high reagent cost, large footprint and low efficiency. In the present work, the aerobic fermentation of the deep dewatering sludge was carried out in a pilot-scale device by optimizing the ratio of different materials. The raw material was the mixture of low-temperature dry sludge with water content of about 60% from the first phase of Xinzhuang Sewage Treatment Plant in Guiyang and auxiliary materials and returned mixture with a proportion of about 13% of the total materials. The temperature and the main product indexes were recorded during the fermentation. The aerobic fermentation was carried out normally even if significantly reducing the dosage of the auxiliary materials to the deep dewatering sludge and footprint after modification of the process, and the modified process also accelerated the temperature rise and shortened the fermentation period.
