INTEGRATED MANAGEMENT SYSTEM FOR SLUDGE IN PLURALITY OF SEWAGE TREATMENT FACILITIES USING ENVIRONMENTAL IMPACT ASSESSMENT AND METHOD THEREFOR

摘要

The present invention relates to an integrated management system for sludge in a plurality of sewage treatment facilities using an environmental impact assessment and a method therefor, which can reduce the total environmental load of a plurality of sewage treatment facilities which is generated within an area by: carrying out an environmental impact assessment for individual sewage treatment facilities on the basis of operation data of the individual sewage treatment facilities and data related to environmental impacts such as power production, drug production, a transportation process, and the like thereof so as to derive quantitative environmental impact indicators such as eutrophication, global warming, human toxicity, acidification, and the like occurring during an operating process of the sewage treatment facilities; and deriving plans which enable integrated management of sludge in a plurality of sewage treatment facilities according to the derived result so as to present the most appropriate management plan for the respective sewage treatment facilities among the plans. According to the present invention, provided is the integrated management system for sludge in a plurality of sewage treatment facilities using an environmental impact assessment, the integrated management system comprising: a data calling part for calling data which is necessary to integrally manage sludge of sewage treatment facilities from a database for storing various data and process operation data including an amount of aeration, an amount of discarded sludge, an amount of returned sludge, an amount of chemical injection, power consumption, a precipitation potential, and concentration of floating materials within a reactor, in sewage treatment facilities; an individual environmental impact assessment part which applies environmental impact assessment techniques to the called data so as to classify data associated with environmental impacts, and which specifies the classified data through the use of the characteristic factors by environmental impact category and derives environmental impact indicators of individual sewage treatment facilities including global warming, eutrophication, acidification, and human toxicity so as to assess environmental impacts on the individual sewage treatment facilities; and an integrated plan presentation part which presents a sludge treatment plan having the lowest environmental impact on the basis of the environmental impact indicators of the individual sewage treatment facilities derived from the individual environmental impact assessment part so as to integrally manage sludge in a plurality of sewage treatment facilities.
