摘要： PURPOSE:To control chemical injection corresponding to the change of an outflow discharge by determining a fuzzy injection ratio control output from the output of a fuzzy inference means, and operating injection volume from the determined fuzzy injection ratio. CONSTITUTION:Chlorine is injected from a chlorinator 2 to a channel well 1, rapidly stirred in a rapid stir pond 3, and then discharged to a coagulation basin 4. Further, the detected outputs of an run-off flowmeter 5 and a residual chlorine concentration detector 6 are supplied to pretreatment equipment 8. The equipment 8 evaluates the respective outputs of the flowmeter 5 and the detector 6, as a fuzzy set, and prepares a control index. An injection ratio arithmetic part 9 has a fuzzy inference part, the fuzzy inference is carried out based on the control index, and the fuzzy injection ratio control output is determined by the fuzzy inference.

摘要： PURPOSE:To economize in energy in the whole of a water conveyance system to prevent overload of a water supply pump by controlling opening/closing of a by-pass valve with the signal from a residual pressure arithmetic unit and controlling the flow rate of conveyance water with the signal from a flow rate control valve controller. CONSTITUTION:The flow rate of conveyance water is obtained by a residual pressure arithmetic unit 10; and if water conveyance from a clear water reservoir 1 to a distributing reservoir 2 does not meet the requirements, a water conveyance pump 5 is operated and a by-pass valve 7 is closed through a controller 11 by the signal from the unit 10. When the lift head of the pump 5 is at a negative pressure in a water conveyance system 3, the flow rate of discharge of the pump 5 is measured by a conveyance water flowmeter and a flow rate control valve 6 is throttled to control the flow rate of discharge of the pump 5. If the conveyance water flowmeter is not provided in the water conveyance system 3, a valve opening degree signal is sent from a flow rate control valve controller 14 to throttle the flow rate control valve 6. Thus, the flow rate of conveyance water is set within a proper operation range of the pump 5.

摘要： PROBLEM TO BE SOLVED: To convert sewer sludge to combustion ash by dehydrating the sludge discharged by a sewage treatment with a sludge dehydrating machine and subjecting the dehydrated sludge to heating decomposition by a heating decomposition furnace, then burning the sludge by a boiler, thereby generating steam. SOLUTION: The sludge discharged from a sewage treatment plant 1 is dehydrated by a centrifugal separating and drying machine 2, by which the moisture included in the sewage sludge is wrung away. Next, the dehydrated concentrated sludge is subjected to the heating decomposition by the heating decomposition furnace 3 after the dehydrated sludge is pulverized. This heating decomposition furnace 3 is heated by the high-temp. steam formed in the boiler 4 or the waste gases discharged from the boiler 4 as a heating source. The org. matter included in the sewage sludge is decomposed and carbonized by such heating decomposition process. The volatile components are discharged outside. The sludge subjected to the heating decomposition is thereafter supplied as fuel to the boiler 4, where the sludge subjected to the heating decomposition is burned to form the high-temp. steam. The formed high-temp. steam is supplied as the heating source of the heating decomposition furnace 3 to the furnace and is supplied as a driving power source of an energy plant 5.

摘要： PURPOSE:To increase the working efficiency of distributed water, by learning the performance data and estimating the daily distributing water volume at every season and the hourly distributing water volume in a day. CONSTITUTION:Weather observation data in every season are extracted by a data- processor 21 and daily distributing water volume in every season and characteristic figures of varying patterns of the hourly distributing water volume are extracted by a data-processor 22. The daily distributing water volume and the characteristic figures of varying patterns of the hourly distributing water volume are estimated by use of these distributing water volume data as instruction signals by means of a learning means 23 learning significance coefficients by the back propagation through a neural network inputting weather observation data and informations classified into week days, holydays, etc. Next, the weather data of the day and the informations such as week day, holyday, or others are input to select an estimating model. The daily distributing water volume and the varying pattern of hourly distributing water volume are estimated, basing on the selected model. These two estimated figures are multiplied to estimate the daily distributing water volume of the day. In this way, the water distributing plan through a day can be submitted and we can also cope with the variation for a long or middle term.
