Description

A kind of bio-trickling device

Technical field

The utility model relates to a kind of sewage disposal device, specifically refers to a kind of bio-trickling device.

Background technology

In prior art, bio-trickling method is low as a kind of cost of development, promotes sewage water treatment method easily and is widely used.In bio-trickling method, microorganism is grown on the filler in bio-trickling device with biomembranous form, pollutent in sewage is degraded in microbial film, microorganism in microbial film is taking organic pollutant as carbon source with the energy, part organic pollutant is converted into harmless water and carbonic acid gas by the katabolism of microorganism, and for microorganism provides energy, another part organic pollutant is converted into the living matter of microorganism self by anabolism.The industrial sewage producing in process of factory production at present, is much all gas-liquid mixed phase, that is to say and in sewage, contain the poisonous or foul smell of stench, and fluid contaminants and the gaseous pollutant of trickling in generally can not simultaneously disposing of sewage.Particularly some bio-trickling devices are ignored the foul smell in sewage completely at present, only consider the pollutent in water body, and directly foul smell are discharged, and environment has still been formed to certain pollution.Because gas is contrary with the flow direction of liquid in trickling, gas, due to light weight, is generally upwards to float simultaneously; And liquid is subject to the effect of gravity and moves downward, for these two kinds of pollutents that flow direction is different, if the purification adopting and filtration unit adopt the mode of imposing uniformity without examining individual cases, nature can be attended to one thing and lose sight of another.But in prior art, lack a kind of bio-trickling device that can well process the sewage that contains waste gas.

Summary of the invention

The technical problems to be solved in the utility model is, provides a kind of and can well process the sewage that contains waste gas, can not cause exhaust gas leakage, more the bio-trickling device of environmental protection.

For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of bio-trickling device, it comprises drips filter chamber, drip in filter chamber and be provided with the padding support frame with mesh, on padding support frame, be filled with microbe stuffing, microbe stuffing top is provided with water spray chamber, padding support frame below is provided with collecting chamber, the top of dripping filter chamber is provided with top scavenge port and drips filter chamber import, the described filter chamber import of dripping is connected with the shower nozzle towards water spray chamber, the bottom of dripping filter chamber is provided with bottom water outlet and bottom ventilator, described dripping in filter chamber import is connected with gas-liquid separator, described gas-liquid separator is provided with sewage import, foul smell outlet and sewage outlet, the main body of gas-liquid separator is the cylindrical structure of bottom with conical flow guiding part, described conical flow guiding part from top to bottom, diameter successively decreases, described sewage outlet is connected with a filter chamber import, described foul smell exit is connected with foul smell treatment chamber, is filled with foul smell adsorption stuffing in foul smell treatment chamber, between the outlet of described foul smell and foul smell treatment chamber, be also serially connected with successively gas meter and gate valve, described gas meter is the intelligent gas meter that accumulative total tolerance reaches preset value and get final product output alarm signal, on described gas meter, is electrically connected with combined aural and visual alarm, described foul smell treatment chamber is connected with foul smell pipeline by rapid-acting coupling.

As improvement, described scavenge port place, top is provided with top ventilator; Top used in air exchange fan is in the air dripping in filter chamber is discharged; Described bottom ventilator, for sucking outside air to drip in filter chamber.
