Title: Method for removing heavy metal contained in sewage
Inventor: WATANABE KEIZABURO
IPC: C02F11/00
Filed: 1992-04-21
Abstract: PURPOSE:To facilitate effective sewage treatment by drying sewage sludge, treating the dry sludge with a dilute aqueous acid solution to dissolve heavy metals, and separating the treated sludge from the solution. CONSTITUTION:When sewage sludge is dried, not only its water content is decreased but also a solid contained in the sludge, strongly hydrophilic colloid, is converted into a hydrophobic solid during heat-drying. The sewage is then treated with a dilute aqueous acid solution, e.g. 0.8-1.0 N nitric acid solution. In this treatment, 1 pt.wt. of the dry sludge and 5-10 pts.wt. of the acid solution are placed in an appropriate vessel, and the mixture is agitated for 10-30min. The sludge from which heavy metals are dissolved out, after being washed with water, is separated from the solution by filtration etc., and is then heated if necessary. For example, when nitric acid is used, heavy metals are removed from the sludge in large percentages: cadmium, about 80%; lead, about 95%; arsenic, about 95%, respectively.

Title: Catalyst deterioration judging device for internal combustion engine
Inventor: MITSUYA NORITAKE
IPC: F01N3/24
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To eliminate an influence caused by change of an EGR condition and judge deterioration of a catalyst correctly. SOLUTION: Air-fuel sensors 13, 15 are arranged upstream and downstream from a catalyst converter rhodium 30 in an exhaust passage of an engine 1. In a control circuit 10, an engine air-fuel ratio is feedback-controlled according to an output of the air-fuel ratio sensors 13, 15, and also it is judged from a locus length of the output of the downstream side air-fuel ratio sensor 15 whether the catalytic converter rhodium 30 is deteriorated or not. In the control circuit 10, the judgment of catalyst deterioration is inhibited in the case where the output of the upstream side air-fuel ratio sensor 13 is fluctuated exceeding a predetermined judgment carrying out air-fuel ratio range from a stoichiometric air-fuel ratio.  Further, in the control circuit 10, a judgment carrying out air-fuel ratio range is set in a narrow range for a predetermined period after EGR feeding is started and stopped by the EGR device 20. It is thus possible to prevent generation of catalyst deterioration error judgment even if when the air-fuel ratio is fluctuated in a short time when the output of the upstream side air-fuel ratio sensor does not follow sufficiently at the time of EGR start and stop.
