Abstract: PURPOSE:To subject a waste fluid to decomposition treatment under a mild condition within a short time without generating secondary environmental pollution by adding an oxidizing agent and an iron salt to the waste fluid containing water polluting org. matter and treating the waste fluid under an acidic condition in the presence of a specific activated carbon material. CONSTITUTION:An oxidizing agent (e.g. H2O2) and an ion salt (e.g. ferrous sulfate) are added to a waste fluid containing water polluting org. matter to adjust the pH of the waste fluid to 4.0 or less and this waste fluid is treated in the presence of an activated carbon material containing 1-5wt.% of nitrogen, 3-30wt.% of oxygen and 40-95wt.% of carbon and having effective meso-pores occupying at least 50vol.% of the total volume thereof. This activated carbon material is obtained by subjecting protein or protein-containing sludge or waste matter to carbonizing treatment at 150-600 deg.C and subsequently subjecting the carbonized matter to activation treatment in a gaseous atmosphere based on steam, carbon dioxide and oxygen at 700-1000 deg.C. As a result, the waste fluid can be subjected to decomposition treatment within a short time under a mild condition without generating secondary environmental pollution.

Abstract: PURPOSE:To enable to integrate a high performance buried hetero structure semiconductor laser and a P-N junction type photodiode by disposing the photodiode at the side with respect to the laser resonance axis. CONSTITUTION:A PD202 which has a carrier generating region which is formed of the same semiconductor material as the active layer of a BH-LD is disposed at the side to the laser resonance axis of a buried hetero structure semiconductor laser (BH-LD) 201, and these two semiconductor elements are electrically insulated via a proton emission insulating layer 203 disposed at the intermediate between two mesas and an SiO2 stripe 204 which insulates two AuZn ohmic electrodes 205, 206. It is necessary that a negative voltage is applied to a common electrode 207 at the electrode 206 for the PD 202 to monitor the laser light scattered from the side surface of the BH-LD201 via the photodiode (PD) 202. Since the proton emission insulating layer 203 exists at this time, no current flows from the electrode 205 to the electrode 206, thereby eliminating the disturbance of the operation of the BH-LD201.
