Title: Disposal of oil-containing waste water
Inventor: OZAWA TERUNORI
IPC: C02F9/00
Filed: 1980-02-14
Abstract: PURPOSE: To reduce the COD value of waste water, which contains soluble oils used for cold rolling, at a low cost under a stable operation, by effectively flocking and separating biological  metabolism-intercepting substances from the oil-containing waste water at a weak alkali, and subjecting to the treated water to a biological disposal using settled bacteria films.   
     CONSTITUTION: Waste water containing soluble oils used for cold rolling is mixed with an acidic  metal salt, and adjusted at a weak alkali level, i.e. pH 8W10, by addition of slaked lime, to facilitate a flocking operation. By this pretreatment, such biological metabilism-intercepting substances  as mineral oils, fats, surfactants, etc. contained in the waste water are deposited stably with metal  hydroxide flocks. The deposited flocks are separated from the waste water by a flocking and compression floating method preferably involving the addition of a high molecular flocculant. The  treated waste water is then subjected to a biological disposal as a higher treatment, because it contains substances decomposable with bacteria such as lower aliphatic acids, alcohols, glycol ethers,  etc,. As for the biological disposal, a stationary process involving two stages in series is adopted.  Ca 2+  ions are converted to calcium carbonate by carbonic acid gas generated in the process for  example, while the disposed water maintaines its pH value near 7W8 and shows a buffering effect  due to generated NH 3 -N. Consequently, it is not necessary to neutralize the disposed water again.

Abstract: PURPOSE:To improve the efficiency of a power converter and to enhance the utility rate of the converter by controlling the control leading angle so that the commutation margin angle of a single-phase full-wave bridge becomes constant and adding a correction to the control delay angle in response to the control amount of the control leading angle. CONSTITUTION:An AC power source Eo is applied through a main transformer T to thyristor bridge TB. The DC output of the bridge TB is connected to a drive motor M and a commutation margin angle detector DT is connected to the bridge. The detector DT generates the commutation margin angle feedback signal FE of the bridge TB to a commutation margin angle controlling comparator DFbeta, which compares it with the reference value Pbeta, and produces a signal Vbeta in response to the deviation. A DC current transformer DCCT generates the current feedback signal IF of a motor M to a current controlling comparator DFalpha, which compares it with the reference value Palpha and produces a signal Valpha in response to the deviation. On the other hand, a synchronizer Sc generates a synchronizing signal to a correcting circuit REV and a distributor DS, and the disstibutor DS produces a gate signal to thyristors Th1-Th4, thereby improving the power factor.
