Title: Process for removing selenium in wastewater
Inventor: ABUMIYA MITSUO
IPC: C02F1/58
Filed: 1999-11-17
Abstract: PROBLEM TO BE SOLVED: To provide an efficient and economical process for removing selenium in wastewater, which is intended for treating wastewater containing hexavalent selenium, such as industrial wastewater, and capable of easily reducing the selenium content in the wastewater to <=0.1 mg/L (effluent standard value) by treatment at room temperature. SOLUTION: This process comprises: introducing wastewater to be treated into a reaction vessel in an air atmosphere under the atmospheric pressure or in a non- oxidizing atmosphere formed by e.g. sealing an upper part of the reaction vessel with gaseous nitrogen or the like; thereafter, adjusting the pH of the wastewater to about 3, adding a reducing agent such as powdery iron to the pH-adjusted wastewater and agitating them together, to reduce the dissolved oxygen content in the wastewater to <=0.5 mg/L; subsequently, adding a divalent iron salt such as FeSO4 to the resulting water, to adjust the pH of the water to 9, to coagulate iron(II) hydroxide and to coprecipitate reduced selenium with the coagulated iron(II) hydroxide;  and when a comparatively high content of iron remains in the water thus treated, further increasing the pH of the water to about 9.5, to perform secondary coagulation of iron(II) hydroxide, to reduce the iron content in the water to <=0.1 mg/L and to obtain the objective treated water; wherein the excess powdery iron or iron salt is recovered from the resulting precipitate and reused.

Filed: 1990-11-28
Abstract: PURPOSE:To accurately stick a tape on the abutting face of an outer flap at the bottom by folding the flap at the bottom of a box material by means of a box material bottom forming unit, holding the flap as folded, moving a tape sticking unit thereto and sticking an adhesive tape at the bottom of the box material. CONSTITUTION:Box materials W are piled up on top a box material feeding unit 4, one piece each of box material W is moved by the box material feeding unit to a box material bottom forming unit 3 and a bottom flap of the box material is folded to form the bottom. While the flap is held as it is folded, a tape sticking unit 100 is moved to the box material to stick a tape on the bottom of the box material. Since the tape is stuck under the condition that the box material W is securely supported by the box material bottom forming unit 3, the bottom of the box material is formed to perfection. Furthermore, a simultaneously folding member 191 is provided at the leading edge of the tape sticking unit 100 to accurately fold the bottom flap immediately before the tape is stuck, followed by tape sticking. At the same time, at the trailing edge of the tape sticking unit 100, a tape followup member 120 is provided to follow up the tape after it is stuck and get the tape steadily adhered to the box material.

Abstract: PROBLEM TO BE SOLVED: To easily synchronize a vertical synchronizing signal even when the period of the vertical synchronizing signal is deviated by providing a following-up range adjusting means varying a synchronization follow-up range corresponding to the period variation of the synchronizing signal. SOLUTION: When a judging result J1 that an input signal does not exist in the follow-up range of the vertical synchronizing signal and a judging result J2 that the input signal itself exists are inputted to each of the two input terminals of an AND circuit A3 when the synchronization of the vertical synchronizing signal is deviated much in the state of supplying a timing pulse Pt0 to a set terminal S, the output of the AND circuit A3 turns from an off state to an on state. Thereby the output of an AND circuit A1 turns from an on state to an off state and next the output of an AND circuit A2 turns from an off state to an on state. As the result of this, a timing pulse Pt2 being the output of the AND circuit A2 is supplied to the reset terminal R of a flip-flop 2 from an OR circuit R1 to magnify the follow-up range of the vertical synchronizing signal.
