Application example:
taking a construction country with a service population of 69000 people and 27 administrative villages as an example, 1 sewage treatment plant with treatment capacities of 3500 tons/day and 600 tons/day in each area planning construction day and 2 sewage treatment stations with treatment capacities of 250 tons/day in each area planning construction day are mainly concentrated in urban and rural areas with population number more than 1500. For the remaining 23 villages, the residences are relatively dispersed, and the treatment capacity is 30-100 tons/day by adopting an intelligent septic tank for treatment. Therefore, the former adopts a direct discharge standard, the latter adopts a resource utilization standard, compared with the whole direct discharge, the resource utilization rate of rural domestic sewage in the whole countryside is improved by about 27% after the treatment by adopting the intelligent septic tank, and the energy consumption mainly comprises the operation power consumption of the biogas slurry lifting pump and the operation energy consumption (including personnel transportation and water resource regulation transportation) of an operation and maintenance service vehicle when the treatment by adopting the intelligent septic tank is carried out.
For rural sewage treatment plants (stations), the energy consumption is about 0.48 tce/ten thousand tons during centralized treatment, is close to a large-scale municipal sewage treatment plant, the energy consumption is about 0.57 tce/ten thousand tons during the dispersion treatment, the average energy consumption of the distributed intelligent septic tanks during treatment is 0.33 tce/ten thousand tons, except the energy consumption, the operation cost of the urban sewage treatment plant is mainly embodied in the medicament cost, the equipment depreciation cost and the personnel wage, the comprehensive operation cost of unit water treatment is 0.79-0.85 yuan/ton, the energy consumption of the distributed intelligent septic tanks is less, the operation cost of intensive management is less, but the cost of depreciation is relatively higher due to high input of automated equipment per ton of water, so that the comprehensive operation cost is lower than that of a town sewage treatment plant, but also accounts for about 82 percent of the operating cost of the traditional urban sewage treatment plant, and the economic investment brought by the operating cost can be effectively made up by charging for water.
It should be noted that the above embodiments are only for illustrating the present invention, but the present invention is not limited to the above embodiments, and any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention fall within the protection scope of the present invention.
