Abstract

A wastewater treatment apparatus is provided that treats wastewater by performing flocculation and magnetic separation by adding a flocculant and magnetic powder to the wastewater and removing magnetic flocs generated thereby. The wastewater treatment apparatus can reduce energy requirements and recover magnetic powder from recovered magnetic flocs with high efficiency with a simple apparatus configuration. Magnetic powder and a flocculant are added to wastewater to generate magnetic flocs. The magnetic flocs are recovered by a magnetic force. After the pressure of the recovered magnetic flocs is increased to a high pressure, the flow rate is increased and the recovered magnetic flocs are decomposed and caused to flow to fluid piping 42 arranged around a cylindrical electromagnet 41. Magnetic powder is caused to attach to the fluid piping 42 by a magnetic force of the electromagnet 41, so that only magnetic powder is recovered. Temperature control and pH control are used in combination to improve the efficiency of decomposing the recovered magnetic flocs.

This disclosure describes a magnetic separation apparatus and a magnetic separation method, and a wastewater treatment apparatus and a wastewater treatment method that allow to obtain clear treated water only with the magnetic separation apparatus without using a filter. Lower halves of two disks arranged in a separation tank are under wastewater when it flows thereinto. A supply portion of the wastewater is provided on one upper wall surface of the separation tank, the wall surface being located upstream in a rotational direction of the disks. In addition, an outlet portion of treated water is provided on the other upper wall surface, the wall surface being located downstream. Consequently, a flow direction of the wastewater and the rotational direction of the disks are the same as each other, a force that detaches magnetic flocs having adhered to the disks is substantially reduced, and thus the filter becomes unnecessary.

CT imaging is performed twice (S1101), which is set as the normal number of rotaions, and a sinogram is corrected (S1102) based on the sinogram obtained by performing CT imaging twice. Since the cycles of data variation caused by respiration are controlled so as not to overlap one another, usually the data variations caused by respiration are eliminated by performing CT imaging twice. However, depending on irregularity in the respiration cycle of the subject, data variation components sometimes overlap at the same angle in spite of the fact that the cycles of data variation caused by respiration are controlled so as not to overlap one another. Therefore, when data variation components remain overlapped at the same angle, CT imaging is performed one additional time (S1104) and the sinogram is corrected (S1102) using the sinogram obtained by performing the additional CT imaging.

Abstract

An oil-contaminated water reutilization system designed to purify any oil-contaminated water occurring at oil production and reutilize the same. The oil-contaminated water reutilization system has the following characteristics. Any oil-contaminated water (W1) occurring at oil production is subjected to flocculation magnetic separation by means of a flocculation magnetic separator (10) to thereby obtain a preliminary purified water (W2) free from the oil-contamination components contained in the oil-contaminated water (W1). From the obtained preliminary purified water (W2), any water-soluble organic matter dissolved in the oil-contaminated water (W1) is removed by a COD removing unit (30) adapted to carry out ozonolysis to thereby obtain a COD treated water (W3). Further, the COD treated water (W3) is distilled by means of a solar heat distiller (50) so as to remove salt contents, thereby obtaining reusable purified water (w4).
