At work, percolate stoste enters water inlet supervisor 42 in the presence of intake pump 41, by water-locator water distribution, from
And make to enter the Sludge Bed anaerobe in the water inlet and reactor of anaerobic reactor and be sufficiently mixed reaction, microorganism decomposition
Organic matter in waste water produces biogas, and gas and water, the mixed liquor of mud rise, pass sequentially through two groups of three-phase separating systems and separated,
By larger collection chamber and larger gas separating interface, the rate of climb of gas, mud, aqueous mixtures can be reduced, is contributed to
Gas separates；Return flow line is advantageous to mud-water separation and sludge settling, strengthens mud-water separation effect；Two groups of three phase separators are common
Effect, helps to be enriched with sludge in reactor, lifts the process performance of reactor.
Gas and part gas-liquid mixture after separation reach Separate System of Water-jet by discharge, through Separate System of Water-jet
Gas discharge after separating treatment, remaining liq lead to water storage when water storage reaches ormal weight, by opening lower water discharging valve 22
Cross down drainage straight pipe 23 and divide water centrum 24 to be flowed out from knock out leg 25, be passed to knock out leg 36 and sprayed to surrounding, formed
Eddy flow, further increase hydraulic mixing.
When reaction is carried out to a certain degree, the receipts mouth of a river 61 of external circulating system sucks one in the presence of circulating pump 65
The part clear liquid separated by three-phase separating system is divided to enter guide shell 62, then the clear liquid is led by circulating pump water inlet pipe 63
Go out, water distribution system is uniformly flowed back into through circulating water pump outlet pipe 67, so uninterrupted circulation forms stable upper up-flow, is reacting
Stable sludge blanket, conversion zone, supernatant layer are formed in device tank body 1, good hydraulic mixing is provided for the inside of reactor tank body 1.
VFC can be realized to external circulating system, enable the external circulating system according to oozing in the frequency-variable controller that circulating pump is set
The change of the real-time water of filtrate and water quality adjusts the operating load of inflow and reactor by recirculated water.In circulation pump water inlet
The water inlet supervisor 42 that a branch road is connected to the water distribution system is also provided with pipe 63, percolate stoste can pass through screw pump
(not shown) enters circulating pump 65 in the lump with cyclic water outlet, so as to increase intake pressure and flow into water distribution system, strengthens
Muddy water mixed effect, the blocking of water-locator can also be effectively prevented using the external circulating system.
When using steam heating, steam mixer 7 mixes to steam and circulation fluid, can effectively solve conventional change
Hot device scale problems.Temperature sensor on reactor tank body 1 is connected with the temperature-sensing valve that automatically adjusts in jet chimney, by certainly
Dynamic regulating valve can automatically adjust heating quantity of steam according to default temperature parameter, so as to realize the real-time control to temperature, with
The effectively operation conditions of control reactor, saves energy, avoids unnecessary energy loss.Wherein, anaerobic reactor reaction temperature
Degree section can be set according to actual conditions in the range of 30-35 DEG C.
Can also be by the inlet pipeline back-flushing structure of setting, i.e., in circulating pump water outlet on the external circulating system of the present invention
Pipe 67 connects a branch road to intake pump water inlet end, so as to utilize the water inlet of tank body hydraulic pressure and circulating pump pressure washing intake pump
End, effectively solves the problems, such as line clogging.
In the above-described embodiments, the bottom of reactor tank body 1 can be arranged to match with water distribution system and sludge drainage system
The structure of falling umbrella, be easy to spoil disposal and water distribution；Tank body ratio of height to diameter is about 2:1, under conditions of same load, it is less than 2 than ratio of height to diameter
Tank body, floor space is small, and water distribution is uniform.Ratio of height to diameter is higher, and rate of circulating flow is bigger, avoids producing dead angle.
In the above-described embodiments, external circulating system is used as two and enters water master by circulating water pump outlet pipe 67 and water inlet supervisor 42
Water inlet tube.Tank base is washed away in the presence of pump pressure is circulated, anaerobic reactor fluidized―bed furnace is more beneficial for and keeps away
Exempt from dead band.
In the above-described embodiments, the spoil disposal branch pipe 51 of sludge drainage system can divide multiple different directions can house steward by centre
52 are connected to spoil disposal supervisor 53, preferably 4~6 directions.The spoil disposal supervisor 53 of tank bottom reaches outside sludge-tank from tank body.This
Outside, the standby mouth of spoil disposal can also be provided with outer circulating line, with for outer circulating line accumulate sludge when, can arrange in time
Go out.
In the above-described embodiments, water inlet supervisor can also reserve acid-adding port, supporting movable small means for feeding acid, need
During cleaning, pickling is carried out, to eliminate line clogging.
In the above-described embodiments, two parallel circulating pumps can also be set in external circulating system according to being actually needed, with
The effect for reaching the using and the reserved or working simultaneously.
" basket filter " of the present invention, as it is known by the man skilled in the art, referring to be used on fluid pipeline filter
The instrument of pipeline debris.It filters the filter structure that hole area is bigger than path tube area 2-3 times, has basket form, works as fluid
Into after the lauter tub for the filter screen for having certain specification, its impurity is blocked, and the filtrate cleaned then is discharged by filter outlet, when need
When cleaning, as long as dismountable lauter tub is taken out, reloaded after processing, working service is extremely convenient.
Those of ordinary skill in the art should be noted that embodiment described in the invention is only exemplary,
Various other replacements, changes and improvements can be made within the scope of the invention.Thus, the invention is not restricted to above-mentioned embodiment,
And it is limited only by the appended claims.
