When horizontal, lancet 173 goes to state straight down, and lancet 173 catches on bag ear 166 by rotation at this time, so that collection be had
The Filter-screen bag 16 of sundries is hooked from screen holder；
Step 3: it stands and the Filter-screen bag 16 on lancet 173 is removed and transported in the operator that sundries is collected on platform 18；
Step 4: it stands in the new installation to the screen holder of Filter-screen bag 16 in the operator on 1 side of filtering ponds, makes the first installation
Column 161 is stuck on the first deck 151, and the second mounting post 162 is stuck on the second deck 152, at this time in the elastic reaction of spring 165
Under, telescopic rod 164 stretches out the state that pedestal 163 is outer and sack is kept to open；
Step 5: filtered sewage is successively discharged into sedimentation basin 25 after conditioning tank 2, anaerobic pond 23 and oxidation pond 24；
Step 6: into sedimentation basin 25, dosing makes sewage accelerate precipitating；
Step 7: the supernatant liquor overflow being precipitated in sedimentation basin 25 enters in clear water reserviors 28, then from top to bottom successively through excessive
After the filtering of heavy activity carbon slab 281, drained by drainage ditch 282, while can be taken out the supernatant liquor of sedimentation basin 25 by water pump 271
Into the agitator tank 27 that makes up a prescription；
Step 8: being taken out the sludge of 25 bottom deposit of sedimentation basin by slush pump 252 and be dehydrated into folded spiral shell formula dewaterer 26,
Then the dry mud of discharge is placed in sludge container 261 and is transported.
The present embodiment is conducive to the effect using anaerobe by setting anaerobic pond 23, hydrolyze organic matter generation,
Acidification and methanation remove the organic matter in sewage, and improve the biodegradability of sewage, are conducive to subsequent Aerobic Process for Treatment.If
Oxidation pond 24 is set, is conducive to carry out biological metabolism under the conditions of having existing for oxygen using aerobic microbiological with degradation of organic substances.
Installation is made up a prescription agitator tank 27 on sedimentation basin 25, by into sedimentation basin 25 dosing be conducive to the precipitating of quickening sludge, to mention
The treatment effeciency of high sanitary sewage.The screen holder of rotation is installed in filtering ponds 1, and places Filter-screen bag 16 on screen holder, is led to
Filtering rack rotation will be in refuse collecting to Filter-screen bag 16.When collecting in Filter-screen bag 16 has a certain amount of sundries, with strainer
The rotation of frame rises, and Filter-screen bag 16 drops under the effect of gravity, and making two lateral edge sliding rail 15 of sack, recess is shunk downward.Pass through rotation
Lancet 173 catch on bag ear 166, thus by collection there is the Filter-screen bag 16 of sundries to hook from screen holder.This set to sewage into
While row primary filtration, the cleaning efficiency to sundries is substantially increased, to ensure that the normal table fortune of Sewage Disposal
Row.
The embodiment of present embodiment is presently preferred embodiments of the present invention, not limits protection of the invention according to this
Range, therefore: the equivalence changes that all structures under this invention, shape, principle are done, should all be covered by protection scope of the present invention it
