Abstract
A water fall aeration-type biofilter is a novel sewage treatment facility and is an improvement of the sewage treatment technology of traditional tower-type biofilters. The biofilter comprises a tower body, filter materials, a grating, an access hole, a water distributor, ventilation openings and a water collecting groove. Sewage stopped by dirt is sprayed out from small holes on the water distributor, and certain water fall heights are set among the filter materials, so that the sewage can be oxygenated before flowing through the filter materials. The ventilation openings are arranged at the periphery of the bottom of the biofilter to be in a fine draft state, so that the sewage, air and the filter materials contact with each other sufficiently. The water fall aeration-type biofilter has higher pollutant mass transfer velocity, thereby being quite favorable for degradation of organic matters and achieving the purpose of increasing biofilter treatment effect.
Description
Technical field
The utility model drop water aeration formula biological filtering tower combined working is applicable to the sewage disposal in hills, area, mountain area, and this device will be realized no energy consumption aerobic treatment sanitary sewage and organic industry sewage.
Background technology
In the common biological filter process for the treatment of waste water, often because oxygen under-supply, oxygen is consumed by the top layer microbial film soon, and the internal layer microbial film of close filtrate is because of can not get competent oxygen, make the breeding of amphimicrobe raised growth, and produce metabolism products such as organic acid, nitrogen, carbonic acid gas and hydrogen sulfide, influence effluent characteristics, when serious even change biomembranous acid base equilibrium degree, cause that the value volume and range of product of micropopulation changes on the microbial film, influence water treatment effect.This is the greatest drawback that biological filter process is handled waste water.Therefore, in the biological filter, keeping competent oxygen-supplying amount is the key point that improves wastewater treatment efficiency.
This drop water aeration formula tower biological filter is to improve a kind of new device that the waste water effect is handled in the biological filter.Utilize the constantly sewage oxygenation over the ground of falling height difference of the another level of one-level, make sewage transverse flow in filter material layer by structure simultaneously, prolong the duration of contact of water and biological filtering layer, thereby reach the purpose that sufficient oxygen supply and bio-contact oxidation are disposed of sewage.
Summary of the invention
In order to realize that to the sufficient oxygen supply of microbial film in the filter tower, this novel filter tower utilizes the falling height difference of the another level of one-level constantly to the sewage oxygenation, reaches the purpose of sufficient oxygen supply.
This drop water aeration formula biological filtering tower combined working device mainly comprises body of the tower, water distributor, filter material layer, grid, supporting plate, access hole, ventilation opening, water leg.Sewage through primary sedimentation pond is sprayed out by the aperture on the water distributor, by certain drop height is set between each filter material layer, makes effluent stream all can finish the process of an oxygenation before each filter material layer.And establish ventilation opening around the bottom of tower, and form the good wind state that pulls out, sewage like this, air, filtrate the three fully contact.Obtain bigger pollutent mass transfer velocity, thereby very help organic degraded.
This drop water aeration formula biological filtering tower combined working is compared with existing tower biological filter has following technique effect:
This novel tower filter can utilize the drop difference of altitude of the another level of one-level, constantly sewage is carried out oxygenic aeration, in every layer of filtering material, form the biological filtering layer of the organic aerobic and double oxygen of absorption degradation, under good ventilation aeration condition, current also transfer to transverse flow filtering layer from traditional top-down direct current, prolonged the time of bio-contact oxidation, and then improved the biological filter sewage treatment effect.

Embodiment:
This novel filter tower device is made up of body of the tower, water distributor, filter material layer, grid, supporting plate, access hole, ventilation opening, water leg; Water distributor water outlet place is positioned under the cat head, and filter material layer places on the supporting plate, and grid is fixed on the supporting plate.Supporting plate is arranged on the body of the tower alternately, and access hole is arranged on the body of the tower alternately, and ventilation opening is positioned on four sides of body of the tower, and water leg is positioned at the bottom of the tower.Sewage through primary sedimentation pond is sprayed out by the aperture on the water distributor, by certain drop height is set between each filter material layer, makes effluent stream all can finish the process of an oxygenation before each filter material layer.And establish ventilation opening around the bottom of tower, and form the good wind state that pulls out, sewage like this, air, filtrate the three fully contact.Obtain bigger pollutent mass transfer velocity, thereby very help organic degraded.
