The present invention provides an exhaust gas purification system. In the exhaust gas purification system, a shower nozzle 20 disperses liquid toward exhaust gas 11 from an upper portion of the exhaust gas 11. The dispersed liquid is mixed with the exhaust gas 11 and thereafter, the liquid accumulates in a tank 30, and odor and oil content are dissolved by action of microorganism included in the liquid in the tank 30. The shower nozzle 20 is connected to an opening 24 horizontally provided in a nozzle pipe 23 connected to a liquid-supply pipe conduit 22. The exhaust gas purification system includes a nozzle 20N directed to a downward dispersing direction of the liquid. The nozzle 20N is placed in the nozzle pipe 23 such that a lower end 20L of the nozzle 20N is located higher than a bottom 25 of an inner wall of a pipe conduit of the nozzle pipe 23. According to this, exhaust gas including odor and oil content is purified.

A cooperative learning system usable for process monitoring in which a monitoring model is provided for each of plural processes arranged in chronological order at predetermined transition time period intervals. The system stores, in chronological order, first monitoring data in a first process, second monitoring data in a second process, and at least one monitoring result from the first process output from a first monitoring model using the first monitoring data as an input parameter. The system performs parent model learning processing for the first monitoring model using the first monitoring data and the monitoring result from the first monitoring model, and performs child model learning processing for a second monitoring model using a monitoring result from the first monitoring model at a first time as teacher data and using the second monitoring data at a second time shifted from the first time by a transition period as an input parameter.

A method for controlling the growth of blue algae in a basin relates to the field of the restoration and protection of the natural ecology on the earth's surface. An ecological water treatment system was constructed for the basin with microorganisms, plants, animals, fillers and the like as main elements by building a novel ecological slope protection at the land-lake ecozone along the banks of the basin and planting eucalyptus in the basin water and/or on the bank of the basin, thereby effectively realizing the efficient nitrogen and phosphorus removal from the basin, controlling the spread of blue algae and improving the environmental water quality.

Process of sewage treatment in a continuous, linear and flexible channel, through a modified aerobic biological reactor system, or transformation of an existing anaerobic biological reactor into a modified aerobic biological reactor, coupled with a modified flexible flotation/decantation system, intended for the sewage treatment, to be carried out in a treatment plant, in a continuous, linear and flexible channel, using, as preliminary treatment, a garbage grid and a sandbox, to remove these debris, followed by a primary treatment, where the sewage receives the primary treatment inside an aerobic reactor—modified MBBR, or inside a pond aerated, facultative or anaerobic, transformed into an aerobic reactor—modified MBBR, or even inside an anaerobic reactor—UASB transformed into an aerobic reactor—modified MBBR, followed by a secondary treatment.
