Detailed description of the invention
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
Embodiment
The purpose of this utility model is achieved through the following technical solutions: as shown in Figure 1 to 4, the horizontal sedimentation tank grouping of the band mud pump house that the present embodiment provides arranges some sedimentation basin unit that mutually can be communicated with, can cut off, often organize described sedimentation basin unit be provided with inhalant region for inputting the sewage treating after-treatment successively, for the settling zone of mud, water sedimentation layering, for discharging the sludge discharging area of heavy mud, and the exhalant region of precipitation water for obtaining after discharging layering; Sludge discharging area is provided with the mud drainage slot 5 that one end is communicated with sludge bucket 3, and the other end of mud drainage slot 5 is connected to one for the mud exteenal reflux pump house 11 and of exteenal reflux for discharging the excess sludge pump house 12 of unnecessary heavy mud respectively by discharge pipeline 4 again; The entrance both sides of mud drainage slot 5 be provided with for heavy mud is scraped into chain slat type mud scraper 6, meanwhile, in mud drainage slot 5, be respectively provided with the chain slat type mud scraper 6 for being scraped by heavy mud into discharge pipeline 4.
Inhalant region is also the hybrid reaction district of horizontal sedimentation tank, and former water mixes at this with coagulant, and reacts, and forms floccule body, then enters settling zone.
Due to heavy pond water inlet flow velocity and uniform water distribution, most important to its sedimentation effect, therefore, as shown in FIG. 1 to 3, in order to make to become a mandarin, sewage evenly enters sedimentation basin with stable, and the perforation tracery wall 2 be provided with for rectification at the water inlet end of inhalant region carries out large resistance water distribution.
By the setting of tracery wall 2 of boring a hole, control aperture flow velocity and be not more than 0.15m/s, thus prevent uneven into water and to the disturbance between settling zone, and then ensure sedimentation effect, avoid short stream and water distribution problem of non-uniform.
Each district is provided with the gate 7 for gauge tap.Inhalant region is provided with inlet channel 1, and exhalant region is provided with effluent weir 13 and outlet conduit 8, and outlet conduit 8 porch is provided with and rotates skimming tool (such as rotating skimming pipe 10) and slag trap 15, for removing the floating scum silica frost of the sewage surface after layering.
In addition, the top of sedimentation basin is provided with steel deck-plate 16, such as, and galvanizing clad can steel deck-plate.When Specific construction is laid, mud exteenal reflux pump house 11 and excess sludge pump house 12 can be laid in inhalant region front end.Such one side can make heavy mud drain with the shortest Distance geometry time, the chain slat type mud scraper 6 arranged by sludge discharging area on the other hand, can by mud after discharge pipeline 4 static pressure spoil disposal, scrape into excess sludge pump house 12 with the shortest time, thus decrease operation energy consumption and floor space, mud exteenal reflux and excess sludge discharge can better be realized.
In order to make this sedimentation basin realize the grouping maintenance of full pond and run, some partition walls can be set in each sedimentation basin unit, make every 2 group one partitions of sludge bucket, to realize dividing into groups to close separately.In addition, each partition wall is also provided with the intercommunicating pore 14 for being communicated with current.Even if maintenance, more exchange device, do not affect the normal operation of other sludge discharging area groups yet like this, thus ensure the normal operation of Sewage Plant.
The utility model adopts many triangle effluent weirs, and back-shapedly lays out tank 9.Even if back-shaped for effluent trough 9 layout can be realized taking minimum area, also all water outlets can be drawn fast.Can not only lower the bearing load of effluent weir like this, and water outlet is more stable, can not disturbance be produced.
In addition, each sedimentation basin and water distribution, spoil disposal etc. all adopt the combining form sharing channel, greatly reduce the loss of flood peak, floor space and house-service gas pipe.
Further, the pond type of sedimentation basin also can be designed to rectangular configuration by the utility model.Be more conducive to mud-water separation like this, the adaptation water yield and sludge concentration change feature greatly, and effluent index is all stably up to state standards.
The settlement of sewage handling process of the horizontal sedimentation tank of band mud pump house of the present utility model is as follows:
As shown in FIG. 1 to 3, first the operation group number of sedimentation basin unit is regulated according to water yield change, make former water by inlet channel 1 and inlet gate, pass through perforation tracery wall 2 uniform water distribution of irrigation channel distribution and setting again, impartial to ensure often to organize the water yield, thus obtain stable, better sedimentation effect; Then the precipitation water after layering is through outlet conduit 8 and rotate skimming pipe 10, is removed easily by the scum silica frost of precipitation water surface; Finally, all the other deposits such as heavy mud are by own precipitation, scrape into mud drainage slot 5 through chain slat type mud scraper 6, and after discharge pipeline 4 static pressure spoil disposal, be connected to the exteenal reflux sludge pump in mud exteenal reflux pump house 11 and the residual sludge pump in excess sludge pump house 12 respectively through sludge pump, realize the outer row of sludge reflux and unnecessary heavy mud respectively.
The utility model can realize integrated sewage precipitation, sludge reflux, excess sludge discharge, water outlet etc. in one; And can according to the change of amount of inlet water, water quality characteristic and environmental condition, flexible adjust operation pattern, can divide into groups to run, overhaul, on raising treatment effect basis, ensure reliability of technology.
Therefore, the horizontal sedimentation tank of band mud pump house of the present utility model, can meet influent quality, the water yield change and variously surmount operating mode, and farthest saved engineering land used and engineering cost.
And the utility model adopts static pressure spoil disposal, sludge discharge effects is stable, contaminant removal effectiveness is high.In addition, the water inlet of sedimentation basin adopts large resistance water distribution, can evenly realize sedimentation effect.Meanwhile, pool inner water position is constant, and settling zone is in free sedimentation state, adds utilization rate of tank volume, improves utilization rate of equipment and installations.
More than describe each preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
