Specific implementation mode
For embodiment just like Fig. 1-7, a kind of two layers of inclined tube of band gas flushing or plate coagulating sedimentation water cleaning systems, main body are on one
The babinet of portion's opening, the babinet include coagulating area and and settling zone, pass through partition board point between coagulating area and settling zone
Every coagulating area is connected to equipped with communication port with the lower part of settling zone in the lower partition, is terminated in the coagulating area
Sewage pipe, sewage pipe are located in coagulating area, and medicament pipe is connected on sewage pipe tube body, and coagulating area is several on two side
The width of a lagging, lagging is less than the distance between two side, and the lagging on two side is interlaced arrangement, interlaced arrangement
Lagging can play the role of blocking and overturning flow.
The side in coagulating area is settling zone, and the bottom of settling zone is the bucket type sludge sump that several are arranged side by side, phase
The side wall of adjacent bucket type sludge sump interconnects, and side wall interconnects, ensure that all precipitations sludge and impurity can all into
Enter into bucket type sludge sump, the bottom of each bucket type sludge sump is connected to sludge discharge pipe, and each sludge discharge pipe interconnects shape
At sludge discharge line, when needing to discharge sludge, sludge is discharged by sludge discharge pipe.
It is that laterally the inclined tube of the entire settling zone of covering or plate area, inclined tube or plate are divided into two layers above bucket type sludge sump,
It is the sorption channel of densely covered inclined direction inside inclined tube or plate area, it, will be remaining thin in flow when flow passes through sorption channel
In small impurity absorption to the inner wall of the surface of inclined plate or inclined tube, under the area of section of the sorption channel of upper layer inclined tube or plate is less than
The area of section of the sorption channel of layer inclined tube or plate；Communication port of the lower end of the sorption channel of lower layer's inclined tube or plate to separate partition board
Direction tilt；The sorption channel inclined direction phase of the inclined direction of the sorption channel of upper layer inclined tube or plate and lower layer's inclined tube or plate
Instead, levels inclined tube or the mutual inclined in opposite directions of plate, increase the baffling of water, can more fully adsorb miscellaneous in clear water
Matter；
The top in inclined tube or plate area is equipped with several horizontal uniformly distributed effluent weirs, each effluent weir at the horizontal plane position of settling zone
Bottom be connected to drainpipe, drainpipe is pierced by the wallboards of box body of settling zone；It is a row between inclined tube or Ban Qu and bucket type sludge sump
Perforation air douche pipeline, perforation air douche pipeline are made of several perforation air douche pipes, wearing in settling zone
Hole air douche pipe is equipped with row's flushing hole, and flushing hole is located at the top of perforation air douche pipe, and this set can pass through
Valve is at any time rinsed inclined tube plate, convenient and efficient；
It is equipped with valve on the sewage pipe, sludge discharge pipe, perforation air douche pipe, water pipe and blow-off pipe.
The area of section of the sorption channel of lower layer's inclined tube or plate gradually increases from close to coagulation area side to the other side
Greatly, be more than the flow velocity of the coagulation area other side close to the flow rate of water flow in coagulation area, this set can balanced both ends flow rate of water flow.
Spacing B, B >=200 can be equipped between the upper layer inclined tube or plate and lower layer's inclined tube or plate.
The height of the coagulating area wastewater level is h1, the water level h2 of settling zone, and the height of water level of drainpipe is

The part that the drainpipe stretches out the babinet of settling zone is connected with horizontal water pipe and downward blow-off pipe, clear
Clear clear water is discharged from water pipe, when needing to rinse inclined tube or plate area, can open blow-off pipe；
The specific work process of this water cleaning systems is as follows：
1. sewage and medicament enter coagulating area from sewage pipe, medicament occurs chemical reaction formation in coagulating area and coagulates
Wadding, under the barrier effect of lagging, left and right overturning during downlink of the mixture of medicament and sewage, be equivalent to its into
Stirring action is gone, such medicament and sewage can be chemically reacted adequately, and the more conducively formation of flocks improves water process
Quality.
2. complete the sewage after reaction enters settling zone by the communication port of lower part, the flocks in sewage are due to inside it
Sludge and impurity are deposited to bucket type sludge sump under the effect of gravity, then will be dirty by the sludge discharge pipe of bucket type sludge sump lower end
Mud and impurity discharge, due to being equipped with valve on each sludge discharge pipe, can according in each bucket type sludge sump sludge it is more
It is few, carry out the cooperation discharge of the mud discharging or multiple sludge sumps of single sludge sump.
3. the clear water after precipitation flows to inclined tube or the plate area on the top of settling zone under the action of flow, inclined tube or plate are to incline
Tiltedly setting, strengthening the blocking to flow and baffling cushioning effect will be tiny in clear water when clear water passes through sorption channel
Contamination precipitation is on inclined tube or plate, the fine impurities in further primary water；Due to the flow rate of water flow close to coagulating area
Comparatively fast, can be arranged lower layer's inclined tube or plate inclined tube or plate from close to coagulation area side to lower layer's inclined tube or the other side of plate
Distance gradually increase, in this way can be balanced by inclined tube or the water flow of plate referring to Fig. 4, reach uniform adsorption effect；
Certain interval can be set between two layers of inclined tube or plate, referring to Fig. 3, achieve the effect that buffer flow.
It is flowed into effluent weir 4. continuing to rise by the clear water of inclined tube or plate area, is discharged from drainpipe.
5. when deposit on inclined tube or plate excessive sludge and impurity after, can by perforate air douche pipeline to inclined tube or plate
It is rinsed, opens the valve on perforation air douche pipe, gas is discharged from flushing hole, rinses out and be attached on inclined tube or plate
Sludge, flushing while, can open the valve on blow-off pipe, and the sewage after flushing is discharged, cesspool is flowed back into；It can root
According to the single perforation air douche pipeline of the flow set of settling zone or plurality of rows of flushing line, rushing on air douche pipe of perforating
Hole flushing may be alternatively provided as it is single or double, to reach best flushing effect.
