Corruption is delivered to after a humification reacts third obtained by stream stock-traders' know-how flow adjustment in mixing arrangement 8 It grows makeup and sets 3, and further with third culturing sludge logistics stock (about 50m3), the aerator in water, which has been selected, destroys sludge It is smaller and pass the aeration that oxygen rate is higher, the preferable tiny bubble air diffusion apparatus of agitating function (aerator in water), in aeration tank Amount maintains 0.03m³air/min.m³~0.04m³air/min.m³.The conveying for flowing to the waste water of sedimentation basin also takes nature The mode of inflow.Aeration process is the process for being aoxidized, being decomposed to organic matter using microorganism.

Due to having enough oxygen contents in fluid in aerator, so as to so that BOD, SS in first-class stock, The substances fast decoupled such as T-N, T-P.The foldback ratio of humification device is 80~120% (examples: inflow water of mixing arrangement flow 180m3/ foldback water 200m3), the processing time in humification device 3 probably needs 17 days on the basis of fine aeration mode.

Four-way overcurrent stock after humification is reacted by be delivered to settler (residence time 12 hours or more, And be equipped with can aggregate and precipitate sludge spatula and stablize the weir device that more flows).Products therefrom is separated into the liquid that top SS is cleaned Fertilizer and sludge stream stock include solid stream stock (microorganism) in precipitated sludge stream stock.

According to analysis, the part that this process middle and upper part is cleaned has the character of liquid fertilizer, can be used as liquid fertilizer, mean parameter Are as follows: PH7.6, BOD 300mgl/L, SS 98mgl/L, T-N 1,500mgl/L, T-P 700mgl/L, as liquid fertilizer nutrition at Point, content are as follows: K (potassium) 2,136mg/Kg, Ca (calcium) 1,887mg/Kg, Mg (magnesium) 265mg/Kg, Na (sodium) Isosorbide-5-Nitrae 64mg/Kg, Fe (iron) 188mg/Kg.

It can be placed in culture apparatus by the precipitation process sludge stream stock obtained comprising solid, culture is in It is sufficiently spread out state, can be located on web plate, upper end setting, which inspires ferment layer (example: can be two layers) close to one layer of culture, is The active silicate of moderate in grain size, partial size is 5~10, with a thickness of the float stone (big stone size as fist) of 5~10Cm, from The farther away layer of culture is catalysis peat, and with a thickness of 1~2Cm, the length for being catalyzed peat is the bullet shape of 2~5Cm.Cylinder The diameter of open upper end part can be about 50cm, and the tank slot as culture apparatus is that diameter is 1.2m~1.5m, high 1.5~2m Cylinder, stainless steel material, bottom be it is latticed, top is taper.

The air diffusion apparatus ventilating air connected by groove tank lower end makes air with catalysis fertile soil and active silicate good Activation (culturing sludge reaction) reaction, on the basis of flowing into the air capacity in culture apparatus, the sky of inflow are generated in good construction Tolerance is 100~200L/Min, and incubation time is 24~72 hours.Various soil are rich in the culture sludge turned out through this process (example: the microorganism is Bacillus sp, Pseudomonas sp, Micrococus sp, Flavoba- to earth microorganism cterium sp.,Bacullus sphaericus.,Bacillus megaterium,Cladosporium, Penicillium, Tricoderma, Stachybotris etc.), and it is returned to the first culturing sludge logistics stock, the training of the second sludge Support logistics stock, third culturing sludge logistics stock.

Second be mixed in aerobic fermentation device passes through stream stock and sawdust and moisture tune by the 5th of stream stock and foldback Moisture content is adjusted to 65~70% after section agent mixing.Average input ratio is second by flowing the 5th of stock about 60%, foldback By flowing stock about 20%, sawdust 16%, other fermentation catalysts (including active silicate, humus) 4%.Lower end utilizes air Device and comb are sufficiently stirred it using screw blender to maintain aerobic conditions.The basic item of aerobic fermentation Part: air is injected in the solid-state lower end of accumulation and starts to stir, the metabolic temperature of microorganism is made after activation of microorganism, that is, is discarded The fermentation temperature of object reaches minimum 50 degree or more.45 degree of initial stage mesophilic digestion or more 5~10 days, 60~85 degree of mid-term hot fermentation 2~7 days in range, 50 degree of later period afterripening fermentation or less 17~27 days, the activity of microorganism is gradually dropped after hot fermentation Low, temperature also begins to decline and maintains between 35~45 degree, and microorganism is gradually transformed into the process of spore state.Aerobic fermentation Device, using 30 days After-ripenings of afterripening fermentation device, finally obtained good solid fertilizer after 30 days fermentation phases. The methods of the solid fertile color of detection, taste, appearance, moisture content are generallyd use, but is mainly still measured on the basis of C/N ratio, It can be judged as the decomposed state that is over when general C/N ratio is below 25%.The content of this solid fertilizer are as follows: nitrogen 1.02%, phosphoric acid 1.6%, potassium 1.8%, moisture 48% is hereinafter, 42% or more organic matter, and C/N is than 25 hereinafter, 5.2 or more rotten degree, PH8.3.
