Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings.Below with reference to
The embodiment of attached drawing description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
Fig. 1 shows a kind of embodiment of hydrolysis acidification tower of the present invention, and 1 bottom of hydrolysis acidification tower tower body is provided with into water system
System 2, which is arranged at intervals with several pulse water-feeding pipes 3, pulse along 1 lower circumference direction of tower body and diametrical direction
Corresponding 1 bottom of tower body of water inlet pipe 3 is provided with conical pod 4.Tower structure is applied to the hydrolysis acidification of waste water by the present invention
Treatment process makes full use of vertical tower body space, extends sludge retention time, stops sludge retention time (SRT) greater than waterpower
Time (HRT) is stayed, that is, relatively reduces hydraulic detention time and occupation area of equipment.Meanwhile the extension of sludge retention time, ginseng
To the biodegradable time it is also corresponding extend, organic matter is sufficiently contacted with the sludge in hydrolysis tower, under the action of anaerobic bacteria,
COD is largely removed, and promotes the fast degradation of organic matter, treatment effect greatly improved.
Water inlet system 2 includes several concentric loop pulses water inlet distribution pipes 5, and pulse water-feeding pipe 3 is arranged at intervals on
Under the pulse water-feeding distribution pipe 5, the high settings such as several pulse water-feeding distribution pipes 5 are radial, pulse water-feeding pipe 3 the pulse into
The regular setting in the lower section of water distribution pipe 5, water inlet position is all corresponding with a pod 4 below pulse water-feeding pipe 3, the pod 4
It is opening down, in use, water inlet is flowed down along 4 side wall of pod.Continuum micromeehanics are changed into pulse by timing open and close magnetic valve
Water inlet, can form bottom sludge in high velocity fluid strikes tower body 1 with gap, without consuming power, stir the sludge of bottom of pond, make
It is constantly sufficiently mixed with waste water in tower body 1, and the organic matter in sludge and sewage obtains sufficient haptoreaction, improves hydrolysis
The muddy water mixed effect being acidified in tower, improves treatment effeciency, reduces energy consumption；
Top is provided with composite filling area 6 in tower body 1, and anaerobic sludge can be set above 6 implantation of packing area, composite filling area 6
It is equipped with overflow weir 7, the water handled is flowed out by overflow weir 7, is additionally provided between composite filling area 6 and overflow weir 7
Return pipe 8, the return pipe 8 are connected with wastewater influent general pipeline 10, carry in return pipe 8 some low concentrations with active
Anaerobic sludge returns to carries out Anaerobic Treatment in advance after wastewater influent general pipeline 10.
Pulse water-feeding distribution pipe 5 is in charge of 9 connection wastewater influent general pipeline 10 by wastewater influent, and wastewater influent, which is in charge of on 9, to be set
It is equipped with solenoid valve 11, is opened in use, wastewater influent is in charge of the solenoid valve on 9 according to certain rotation, that is, opens one
Remaining solenoid valve is closed while a, such to allow regional area water inlet flow velocity is opposite to accelerate, and is given in sludge and sewage
Organic matter obtains sufficient haptoreaction, improves the muddy water mixed effect in hydrolysis acidification tower.
1 bottom of tower body is additionally provided with sludge pipe 13, when mud amount is excessive, can pass through sludge pipe spoil disposal.
The present invention also provides a kind of sewage water treatment methods, in use, opening any one electromagnetism outside hydrolysis acidification tower
Valve；Sewage is injected into the hydrolysis acidification tower, impacts the sludge of 1 bottom of tower body；After separated in time, above-mentioned electromagnetism is closed
Another solenoid valve is opened while valve；Continue to inject sewage into the hydrolysis acidification tower, continues to rush in another position
Hit the sludge of 1 bottom of tower body.So as to form bottom sludge in high velocity fluid strikes tower body 1 with gap, without consuming power,
The sludge for stirring bottom of pond is sufficiently mixed it constantly with waste water in tower body 1, and sludge is adequately connect with the organic matter in sewage
Touching reaction.
The present invention can minimize, modularized design.Both it is high to have efficiently solved conventional hydrolysis acidification technique pond cost, had accounted for
Ground area is big, the problem of poor processing effect；It is special again without configuration high as UASB type, EGSB anaerobic reactor, high investment
Not Shi Yongyu middle concentration C ODcr 3000mg/l or so waste water processing.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
Member for, without departing from the principle of the present invention, can with several improvements and modifications are made to the present invention, these improve and
