technical field

The utility model is a continuous full-automatic integrated fermentation equipment, which can be used for urban sludge disposal, livestock and poultry manure composting, silage feed fermentation and soil restoration, and can also be used for the fermentation of other solid materials.

Background technique

According to statistics, more than 80% of urban sewage treatment plants in my country have a treatment capacity of less than 50,000 tons per day, and nearly 50% of urban sewage treatment plants have a design capacity of less than 20,000 tons per day. According to the estimation that the amount of sludge produced is 10/10000 of the amount of sewage treatment, 80% of the sewage treatment plants in my country have a sludge production of less than 50t/d, and nearly 50% of the sewage treatment plants have a sludge production of less than 20t/d. my country's sewage treatment plants supporting small sludge projects accounted for more than 80%. For sludge plants with a daily sludge output of less than 50 tons, the relatively high construction cost per ton leads to large investment. Therefore, how to reduce the construction cost is an important technical problem that needs to be solved urgently.

The standardized sludge aerobic fermentation project is mainly composed of mixing system, fermentation system, deodorization system and supporting electrical automatic control system. The mixing system, fermentation system and electronic control system are all set up in relatively independent workshops, and the investment is relatively high; the odor treatment capacity is also large, and an independent large-scale biological filter needs to be set up, and the cost is also high. When these systems are used in large-scale sludge aerobic fermentation projects, the frequency of use is high and the scale benefit is good. However, when applied to small-scale sludge treatment projects, the frequency of use of most facilities is very low, and the economy of investment is poor.

In terms of project operation, the staffing of large-scale sludge aerobic fermentation projects generally includes professionals in environmental protection technology, mechanical equipment, electrical engineering, etc. The operation and maintenance team is relatively large, and the requirements for personnel quality are high. However, it is difficult for small-scale sludge treatment projects to be fully equipped with various professional personnel, and the technical level of personnel is also difficult to meet the operational requirements. Compared with large and medium-sized projects, small-scale sludge aerobic fermentation projects have higher requirements in terms of operational stability and convenience. Therefore, the utility model integrates the mixing system, fermentation system, deodorization system and supporting electrical automatic control system in the sludge aerobic fermentation project into one piece of equipment, and adopts the automatic control of the whole process of the electrical automatic control system. Low civil construction cost, less investment, short construction period, energy saving, and simple installation site requirements.
