摘要： PURPOSE: To improve the energy density and utilization rate as compared to methane fermentation by bringing a product obtd. by the acid fermentation of org. waste into a photocatalyst in the presence of light to produce hydrogen.
CONSTITUTION: Org. waste is charged into an acid fermentation vessel 1b from a duct 4. It is kept at 30W60°C with warm water subjected to heat exchange in a heat exchanger 3 between a warm water duct 9 and a circulating duct 8, and acid fermentation is carried out while agitating the waste with hydrogen fed from a circulatng blower 11a. A fermented product in the vessel 1b is charged into a hydrogen producing vessel 13 through a duct 5 and brought into contact with a photocatalyst 14. At the same time, sunbeams 17 are irradiated through a light transmitting roof 15 to generate hydrogen. Part of the hydrogen is fed to aerators 16 through a blower 11b. Waste liquor after the reaction is fed to a solid-liq. separation vessel 19 through an outflow path 18, and the separated liq. is discharged from a discharge path 20. The remaining solid is returned to the vessel 13 through a duct 22.

摘要： PURPOSE:To prevent a decrease of the quantity of effective ozone consumed for preventing slime by substituting a clear water, etc. for water to be measured resident in each part of an equipment prior to an ozone washing and performing the ozone washing. CONSTITUTION:After a measurement for the water quality of the water to be measured is carried out a pump 8 is turned on, valves 6, 9d, 9e are opened and the other are turned off or closed. Thereby, the clear water stored in a wash water vessel 7 is substituted with the water to be measured. Furthermore, a side of a water sampling pump 2 is substituted similarly with the clear water by the valve changeover action of 9c, 9d. Then a pump 9b is turned on, while turning on the pump 8, and the valve 9d is opened and the other are turned off or closed, thereby, the water containing ozone is introduced to the side of a water receiving vessel 5. Furthermore by changing over the valves 9c and 9d, the water containing ozone is introduced to the side of the pump 2 and the washing operation is performed. Thereby, high concn. of the remaining ozone can be maintained and the decrease of the quantity of the effective ozone can be prevented.

摘要： PURPOSE:To exchange heat at high efficiency, by absorbing the latent heat into steam by vaporizing liquid on the high temperature side, and by condensing the steam by contacting it to liquid on the low temperature side. CONSTITUTION:Since a heat exchanger body 1 is a sealed container, steam vaporizing from the surface of liquid 4 in high temperature, as shown by arrow signs 6, in a chamber 9 on the high temperature side, moves to a chamber 10 on the low temperature side, passing through a window 3 provided to the upper part of a bulkhead as shown by an arrow sign 7, by the difference of the steam pressure. Then, the steam passing through the window and getting into the chamber 10 moves to the surface of liquid in low temperature, as shown by arrow signs 8, condensing on the surface of the liquid in low temperature. In this manner, heat can be exchanged at high efficiency.

摘要： PURPOSE:To reduce the heating energy of a heating means for sludge in a primary digesting cell, in the system for digesting sewage sludge or the like, by recovering heat by heat exchange between withdrawn sludge and charged sludge. CONSTITUTION:Charged sludge is heat-exchanged with withdrawn sludge by a heat exchanger 13 provided on the way of a pipe line 4 for charged sludge, further heated by a heating means 3 and then charged in a primary digesting cell 1. On this occassion, the valve 17a of a pipe line 8 for circulating sludge is held under a closed or squeezed condition. After the operation of charging sludge is completed, the valve 17a is opened and a valve 17b for charged sludge is closed to circulate and heat the sludge in the primary digesting cell 1. When the withdrawal of sludge is completed in synchronization with the completion of charging sludge, the valves 17c, 17d of a withdrawing pipe line 6 are closed, and the valves 17e, 17f of branched pipe lines 15, 16 are opened so that the sludge or water stored in a reserving cell 14 is circulated to inhibit a blockade in the pipe line 6 and the pipe of the heat exchanger 13.

摘要： PURPOSE:To stabilize the quality of purified water, while holding the total amount of sludge in the system at a predetermined value, in purifying sewage or the like, by setting the total amount of sludge at first, and using the set value and an estimated value for the total amount of sludge obtained from information at a specified point to set the amount of excess sludge to be withdrawn. CONSTITUTION:From the output of an MLSS meter 6 inserted into an aerating cell 1, the total amont of sludge is calculated by an arithmetic circuit 7 for the total amount of sludge. On the other hand, an estimated value for the total amount of sludge is calculated by an arithmetic circuit 8 taking into consideration the quality of water to be purified, the property of sludge, the amount of air blow and the amount of excess sludge to the withdrawn. The set value of the total amount of sludge from the arithmetic circuit 8 and the estimated value for the total amount of sludge from the arithmetic circuit 7 are inputted to an arithmetic circuit 9 to determine the amount of excess sludge to be withdrawn. In addition, the outputs of a flow meter 11 for excess sludge and a densitometer 10 for excess sludge are processed by an arithmetic unit 12 to calculate the actual amount of excess sludge to be withdrawn. The output of the arithmetic unit 12 and the output of the arithmetic circuit 9 are inputted to a controller 13 for withdrawing excess sludge, withdrawal is performed by the operation of an excess sludge-withdrawing pump 4, and the total amount of sludge is held constant.

摘要： PURPOSE:To hold the total dry amount of sludge in the system at a predetermined value with the easy management of operation, by measuring the amount of sludge flowing into an aerating cell and the total dry amount of sludge in the system, and adding a feed-back controlling amount to said amount of inflow sludge to obtain the amount of excess sludge to be withdrawn. CONSTITUTION:From values measured by a meter 6 for the amount of inflow sewage and a densitometer 7 for the concentration of SS in the inflow sewage, the amount of sludge flowing into a aerating cell 1 is calculated by the first circuit 8 at every cycle of controlling. The total dry amount of sludge in the system is calculated from MLSS, the amount of inflow sewage, etc. by the second circuit 9, averaged and used for control. A correcting controlling part for the amount of excess sludge is calculated by the third circuit 10 using the total dry amount of sludge obtained by the second circuit 9 as a controlling amount. An output from the first circuit 8 is added to that from the third circuit 10 by the forth circuit 11 to calculate the amount of excess sludge to be withdrawn. The actual amount of excess sludge to be withdrawn is calculated by an arithmetic unit 12 and compared with an objective value for the amount of excess sludge to be withdrawn by a controller 13 to dispatch a signal for starting or stopping an excess sludge pump 3.

摘要： PURPOSE:To obtain the flocculant pouring control apparatus capable of easily controlling the outlet turbidity of a precipitation basin to a set value even if the flow amount of raw water is varied, by a method wherein the signal of the flow amount of raw water is put in a treated water set turbidity operator and the set value of treated water turbidity is calculated in accodance with the flow amount of raw water. CONSTITUTION:The set value of the outlet turbidity of a precipitation basin 2 by a precipitation basin outlet turbidity setting device 11 and the flow amount of raw water by a raw water flowmeter 3 are put in a treated water set turbidity operator 12 to calculate treated water set turbidity. This treated water turbidity set value is sent to a ratio operator 9 and compared to the treated water turbidity value by a treated water turbidimeter 8 to calculate a flocculant pouring ratio and this calculated value is sent to a pouring amount controller 6. A proper pouring amount of a flocculant is poured into a rapidly stirring basin 1 by the controller 6, the feedback signal of a flocculant flowmeter 4 and a manipulation device 5.
