Description

TECHNICAL FIELD

[0001] The utility model relates to the field of sewage treatment and resource technology, especially to a biochemical device of integrated assembly reducing biochemical energy consumption. BACKGROUND

[0002] Biochemical pond energy consumption is an important issue in the field of sewage treatment, which directly relates to the operation cost of sewage treatment plant, energy utilization efficiency and environmental protection effect. High biochemical pond energy consumption not only increases the cost of sewage treatment, but also may have negative impact on the environment and economy. The specific performance is as follows:

[0003] Cost increase: high energy consumption leads to the increase of sewage treatment cost, which brings economic pressure to the sewage treatment plant.

[0004] Resource waste: unnecessary energy consumption wastes valuable energy resources, which is contrary to the concept of sustainable development.

[0005] Environmental pollution: if fossil energy is used as power source, high energy consumption will increase carbon emissions and aggravate environmental pollution problems.

[0006] In a sewage treatment plant using biochemical process, the biochemical pond as the main monomer is self-evident. With the progress of technology and the improvement of environmental protection requirements, more and more sewage treatment plants begin to use integrated device instead of traditional civil structure biochemical pond. This change not only improves the construction efficiency, but also optimizes the sewage treatment process and reduces the operation cost. Although the existing integrated device has the advantages of short construction period, small land occupation, low operation cost and convenient maintenance, etc., but there are problems of high energy consumption caused by unreasonable structure in the pond body and poor convenience of recycling and reuse of the pond body.

[0007] Therefore, the utility model is proposed. CONTENT OF THE UTILITY MODEL
