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 computer readable medium including a program for a computer connected through a network to a central control device for controlling a treatment tank for treating wastewater with a microorganism that can degrade a specific compound, wherein the program allows the computer to realize: 
 a concentration measuring function of measuring a concentration corresponding to a concentration of the specific compound in the treatment tank; and    a transmitting function of transmitting the concentration value measured to the central control device.    
     
     
         2 . A computer readable medium including a program for a computer for controlling a plurality of treatment tanks for treating wastewater, in which the treatment tanks is located in buildings physically apart from each other, wherein the program allows the computer to realize: 
 a receiving function of receiving a concentration value corresponding to a concentration of a specific compound before treatment and a concentration value corresponding to a concentration of the specific compound after treatment;    a computing function of computing a difference between the concentration before treatment and the concentration after treatment which have been received; and    a concentration-controlling function of controlling difference information indicating the computed difference between the concentration before treatment and the concentration after treatment.    
     
     
         3 . A computer readable medium including a program for a computer for controlling a plurality of treatment tanks for treating wastewater, wherein the program allows the computer to realize: 
 a predetermined value-control function of controlling a predetermined value determined on the basis of a concentration of a specific compound in each of the treatment tanks, so that the predetermined value is associated with each of the treatment tanks;    a receiving function of receiving difference information specifying a difference between a concentration of the specific compound before treatment and a concentration of the specific compound after treatment;    a comparison function of comparing a difference between a concentration value corresponding to the concentration before treatment and a concentration value corresponding to the concentration after treatment, in which the difference is specified by the difference information received, to the predetermined value that has been controlled; and    a processing function of conducting a predetermined treatment on the basis of the results of comparison by the comparison function.    
     
     
         4 . A computer readable medium including a program for a computer connected through a communication network to a central control device for controlling a wastewater treatment of using an activated sludge tank containing a microorganism that can degrade a hardly biodegradable compound, wherein the program allows the computer to realize: 
 a concentration measuring function of measuring a BOD value and a characteristic value corresponding to a concentration of the hardly biodegradable compound in the activated sludge tank; and    a transmitting function of transmitting the BOD value and the characteristic value measured to the central control device.    
     
     
         5 . A computer readable medium including a program for a computer for controlling a plurality of treatment tanks for treating wastewater, in which the treatment tanks are located in buildings physically apart from each other, wherein the program allows the computer to realize: 
 a receiving function of receiving BOD values and characteristic values corresponding to concentrations of a specific compound before and after treatment;    a computing function of computing a difference between the BOD values before and after treatment and a difference between the characteristic values before and after treatment, which have been received; and    a concentration-controlling function of controlling difference information indicating the difference between the BOD values before and after treatment and the difference between the characteristic values before and after treatment, which have been computed.    
     
     
         6 . A computer readable medium including a program for a computer for controlling a plurality of treatment tanks for treating wastewater, wherein the program allows the computer to realize: 
 a predetermined value control function of controlling each predetermined value determined on the basis of a BOD value and a concentration of a hardly biodegradable compound in each of the treatment tanks, so that the predetermined value is associated with each of the treatment tanks;    a receiving function of receiving difference information specifying a difference between the BOD values before and after treatment and a difference between the concentrations of the hardly biodegradable compound before and after treatment in each of the treatment tanks;    a comparison function of comparing the difference between the BOD values before and after treatment, and the difference between the concentrations of the hardly biodegradable compound before and after treatment, which are specified by the difference information received, to the predetermined value that is controlled; and    a processing function of conducting predetermined treatment on the basis of the results of comparison by the comparison function.
