  摘要:

  发酵周期是决议城市污泥好氧发酵项目可否到达预期运转结果的要害设想参数，也是影响项目占地面积和项目造价的主要参数。从脱水减量化、高温无害化、不变腐熟化等角度，连系发酵产品用处、尺度要乞降项目实践，切磋适合的好氧发酵周期，为项目设想供给鉴戒。研究注解，最少15 d的主发酵周期才能到达脱水减量化和无害化部门目标要求。若产品用在燃烧，主发酵周期可设为15 d；若用在地盘改进，主发酵周期最少设为20 d；若进行农林地操纵，建议主发酵后接续后腐熟，全周期最少设为30 d。是以，在项目实践中，主发酵周期最少设为15 d，后腐熟时候可按照产品用处设为5~15 d或更长。

  Abstract:

  Fermentation cycle is a key design parameter that determines whether the municipal sludge aerobic fermentation project can achieve the expected performance, and also an important parameter that affects the project footprint area and construction investment. From the aspects of dehydration reduction, microbial inactivation and maturity, the suitable aerobic fermentation cycle was discussed based on the product applications, standard requirements and engineering practices, which aimed to provide reference for engineering design. The main fermentation cycle to meet part of the dehydration reduction and microbial inactivation index requirements should be at least 15 days. If the product was used for incineration, the main fermentation cycle could be set to 15 days, and at least 20 days for soil conditioner. If the product was used as fertilizer in farmland or forestland, it was recommended that the whole cycle of main fermentation and subsequent maturity should be at least 30 days. In engineering practice, the main fermentation cycle should be at least 15 days, and the maturity cycle could be set to 5-15 days or longer depending on the use of the product.
