Wastewater treatment control system, terminal, computer program and accounting method

Abstract

A wastewater treatment control system for controlling a wastewater treatment of using a microorganism that can degrade a specific compound, comprises measuring a specific value corresponding to a concentration of the specific compound in wastewater, and controlling the wastewater treatment on the basis of the specific value.

1 . A method of accounting for a wastewater treatment service with a wastewater treatment control system for controlling a treatment tank for treating wastewater with a microorganism that can degrade a specific compound, wherein the wastewater treatment control system includes a terminal for obtaining data relating to the treatment tank and a central control device communicating with the terminal through a network, wherein the terminal has a concentration-measuring unit for measuring a concentration value corresponding to a concentration of the specific compound in the treatment tank and has a transmitting unit for transmitting the concentration value measured by the concentration-measuring unit to the central control device, and wherein the central control device receives the concentration value of the treatment tank from the terminal, the method comprising: 
 accounting in proportion to a reduction in cost by an introduction of the wastewater treatment system, compared to a cost previously required for draining the wastewater.    
   
   
       2 . A method of accounting for a wastewater treatment service with a wastewater treatment control system for controlling a wastewater treatment of using an activated sludge tank containing a microorganism that can degrade a hardly biodegradable compound, wherein the wastewater treatment control system includes a measuring unit for measuring a BOD value and a characteristic value corresponding to a concentration of the hardly biodegradable compound in wastewater and a controlling unit for controlling the wastewater treatment on the basis of the BOD value and the characteristic value, the method comprising: 
 accounting in proportion to a reduction in treatment cost by an introduction of the wastewater treatment system, compared to a treatment cost previously required for draining the wastewater.
