The present invention relates to an air pollutant removal apparatus with multifunction for the effective cleaning of particulates and gas absorption for removing exhaust gas from waste incinerator, polluting gas from industrial process, and bad smell substances in the air. The air pollutant removal apparatus with multifunction for the effective cleaning of particulates and gas absorption includes multiple cleaning absorption modules each of which consists of a cleaning absorption solution inlet, a cleaning absorption solution outlet, a gas-liquid separator, and a gas-liquid contact in a horizontal direction. The air pollutant removal apparatus with multifunction for the effective cleaning of particulates and gas absorption includes a polluting gas inlet, a treated gas outlet, and an undercurrent wall for the cleaning absorption modules so that the polluting gas can passes through the cleaning absorption modules in order, but the cleaning absorption solutions independently put in and out each cleaning absorption module so that various pollutants can be treated in one reactor according to the use of various cleaning absorption solutions. The gas-liquid contact includes a perforated plate, a gas-liquid contact media, and a polluting gas collision and undercurrent device so air pollutants such as bad smell substances, sulfur oxides, nitrogen oxides, carbon monoxide, carbon dioxide, volatile organic chemical materials, and lead can be effectively removed.

CONSTITUTION: A non-power rainwater filtering and collecting device comprises an initial rainwater exclusion module(1), an initial rainwater storage tank(2), a rainwater filter(3), and a rainwater storage tank(4). The initial rainwater exclusion module comprises a water collection weir(7), a screen(6), and a contaminant prevention pipe(8). The initial rainwater exclusion module excludes initial rainwater through a gutter(5). The initial rainwater storage tank comprises a flow maintenance small valve(9), an initial rainwater storage tank drain(10), and an initial rainwater storage tank outlet(11). The rainwater filter settles large and heavy particulate contaminants in a sedimentation space(13) and additionally filters the rainwater through a filter medium layer(14). The rainwater storage tank stores the rainwater which moves through a backwash water storage space(15) in the upper part of the filter medium layer and a rainwater filter outlet(17).

PURPOSE: Waterworks for facilitating cleaning and sludge discharge and a hybrid filter for treating sewage ad wastewater are provided to reduce the size of a sewage and wastewater treating apparatus and a site area by performing filtering, precipitation, and ultraviolet ray sterilization through one filter. CONSTITUTION: A supply source of processed target water is connected to a lower space(3) of a filtering layer(2). A substance on particle or the precipitation of flock is removed by combining settling basins(5,6). The target water is filtered with an upward flow type. The substance on particle or flock is additionally removed among the target water.

PURPOSE: A flocculation basin for treatment of drinking water and wastewater is provided to remarkably reduce the size of a structure and a site area by shortening flock forming time. CONSTITUTION: A filter-type flock forming module(2) forms fine particles in flock. When processing target water is collided with a wall firstly in a mixing flock forming module(3), an eddy is formed. The inter-particle collision is induced through a stirring operation in an eddy forming process. In an upflow-type flock forming module(4), rising speed is increased. The rising speed of large flock is reduced. In a mechanical mixing flock forming module(5), the flock is formed through the rotation of the mixing device.
