Problems solved by technology

However, with the development of society, it is becoming more and more difficult to occupy a large amount of land. In addition, the existing dewatered sludge aerobic fermentation process has high energy consumption for oxygen supply during operation, and the internal fermentation of the pile is impermeable. During the composting process It will also emit odor and pollute the environment, and compost products cannot meet the requirements of stabilization, harmlessness, reduction, resource utilization and relevant national standards, thus hindering the promotion and application of aerobic fermentation technology in sludge treatment

Embodiment Construction

[0014] The specific implementation manners of the present invention will be described in detail below. A kind of aerobic fermentation process is characterized in that comprising the following steps:

[0015] (1) Mixing stage

[0016] The sludge with a moisture content of 80% is transported to the treatment plant, poured directly into the silo, and the municipal sludge, back-mixed material, and conditioner are evenly transported to the mixer through an automatic metering device and fully mixed to make the material reach a suitable level. Moisture content, and ensure that the mixture has a loose structure to meet the free air space requirements for fermentation;

[0017] (2) Biological fermentation stage

[0018] After the fermentation mixture enters the fermentation device from the feed port, it moves slowly through the conveying device at a certain speed according to the production situation, and the decomposed material after fermentation is automatically removed from the ot...

Abstract

The invention discloses an aerobic fermentation process. The process comprises the following steps: (1) a mixing stage, and (2) a biological fermentation stage. The process provided by the invention is suitable for aerobic fermentation treatment of sludge in small and medium-sized sewage treatment plants, innocent treatment of urban garbage, innocent treatment of livestock and poultry excrement and other organic solid waste and the like; and the process is particularly suitable for occasions on which generation sources of solid waste are relatively scattered and large-scale centralized processing is not easy to perform.

Description

technical field [0001] The invention belongs to the field of fermentation, and in particular relates to an aerobic fermentation process. Background technique [0002] With the rapid development of urbanization, the requirements for urban environmental governance have increased and the urban sewage treatment system has been improved, the amount of sewage plant sludge to be treated is huge, and due to the special quality of sludge, not only has a high water content, but also contains organic Substances, nitrogen and phosphorus, heavy metals and salts, as well as pathogenic microorganisms and parasite eggs are perishable and emit a strong odor. If they are not treated effectively, they will damage the environment, pollute water and soil, and endanger human health. The treatment, disposal and utilization of sewage plant sludge has become the focus of urban construction and development. At present, the treatment and disposal of sewage sludge is mainly through incineration, landf...
