Description
Technical field
The invention belongs to waste processing arts, relate to a kind of biological deodorizing tower using bacterium chaff as raw material, using rice husk as conditioner particularly.
Background technology
Odor pollution to ecological environment and human health cause very harmful, in widespread attention in the world.Conventional processing technique is physical-chemical process mainly, and current bioanalysis becomes one of main method of purification odorant gradually.Bioanalysis utilizes microorganism by odorant degraded or the process being converted into odorless or low sordes matter.Compared with physical chemistry processing method, biological deodorizing needs to add chemical agent hardly, and owing to running under normal temperature, normal pressure, the waste of energy is also relatively low, and does not produce secondary pollution.Biofilter, because its cost is lower, convenient operation, is widely used in the place that destructor plant etc. easily produces foul smell.Its main deodorizing principle relies on filler to adsorb foul gas, utilizes the microorganism grown in filler to carry out decomposition and inversion to foul gas composition simultaneously.The filler of biofilter has a variety of, and degradable solid packing causes the extensive concern of researcher due to advantages such as convenient transportations, easily filling, reusable edible in recent years.
Bacterium chaff (also known as mushroom residue, bacterium slag etc.) refers to compost discarded in plantation edible mushroom filter process, still can biological utilisation composition containing rich in protein, amino acid, polysaccharide, cellulose etc. in discarded bacterium chaff, the macroelements such as nitrogen, phosphorus, potassium, calcium, the trace elements such as Yi Jitie, manganese, copper, zinc.And wherein also remain a certain amount of active microorganism.Along with the development of China's mushroom industry, cause the bulk deposition of bacterium chaff, this not only pollutes surrounding body and soil etc., and the serious Recycle mechanism disturbing mushroom industry.
Existing part researcher has carried out utilizing bacterium chaff to produce the research of feed and fertilizer at present, but has no bacterium chaff is mixed with biological deodorizing filler by report research as raw material and rice husk.Therefore, the present invention makes full use of the feature that bacterium chaff is loosely organized, be rich in a large amount of active material and degradable microorganism, the good rice husk of, graininess large with specific area mixes as microbe carrier, prepares the odor removal of biologic packing material for composting plant and destructor plant.

Accompanying drawing explanation
Fig. 1 is bacterium chaff filler biological deodorizing tower structural representation of the present invention.
Primary clustering symbol description in accompanying drawing:
1 air pump; 2 intake valves; 3 porous plates; 4 geotextiles; 5 bacterium chaff fillers; 6 air outlet valves; 7 discharge outlet; 8 water pumps; 9 spray equipments; 10 spray ponds.
Detailed description of the invention
Bacterium chaff filler biological deodorizing tower provided by the invention, primary structure is: air pump, by the intake valve of pipeline coupled reaction device; Bottom in deodorizing tower should be provided with porous plate, and lay one deck geotextiles above porous plate, geotextiles is filled bacterium chaff filler; Be provided with spray equipment above filler, be connected to spray pond by water pump; Foul smell after process directly discharges through reactor air outlet valve.
Bacterium chaff filler of the present invention bacterium chaff is crushed to particle diameter be less than 1cm, airing 12-48h to moisture content lower than 30%, be uniformly mixed in batch mixer after mixing according to the ratio of weight ratio 1: 0.5-1: 1 with rice husk, adopt bar buttress formula after mixing or be placed in tank diameter and carry out stabilisation; Can also add a small amount of deodorization functions microbial inoculum in bacterium chaff filler, the deodorization functions microbial inoculum that the present invention adopts comprises commodity microbial inoculum or adopts the known technology bacterial strain of separation and concentration or microbial inoculum bacterial classification needed for screening voluntarily.
Can also add appropriate conditioner in bacterium chaff filler of the present invention, conditioner can be bentonite, gangue, fertile soil etc., makes material keep loose, strengthens aeration and adsorptivity; Conditioner gross weight mostly is 1/5 of bacterium chaff filler gross weight most, can determine as the case may be.Bacterium chaff filler stabilizing take can not be less than 3 days, according to circumstances can carry out turning or ventilation in good time.In bacterium chaff filler, moisture content is 30 ~ 35%, and moisture content is too low is unsuitable for growth of microorganism, and water content is too high causes the increase of material viscosity to be unfavorable for stabilisation.
Below in conjunction with accompanying drawing, the present invention is elaborated.
Pump into deodorizing tower in by pending foul smell through intake valve 2 by air pump 1, foul smell flows through and configures and pile the bacterium chaff filler 5 put well, the efficient H removed in foul smell under the effect of microorganism
2s, NH
3, realize the deodorization functions of foul smell, the foul smell after process directly discharges through deodorizing tower air outlet valve 6.
One deck geotextiles 4 laid by porous plate 3 in deodorizing tower, to blast in process at foul smell to prevent bacterium chaff filler and be scattered out by the space of porous plate 3.
When bacterium chaff filler moisture content deficiency, by water pump 8, the nutrient solution of configuration in spray pond 10 is evenly sprayed at bacterium chaff filling surface by the spray equipment 9 above deodorizing tower.
Ponding is too much bottom deodorizing tower, opens discharge outlet 7 and unnecessary sewage is released.
The method of bacterium chaff filler domestication of the present invention is:
First by laid on the porous plate of deodorizing tower for the bed mud of inoculation, microbial culture medium adds aeration in deodorizing tower, and the formula of microbial culture medium is: glucose 0.42g/L, K
