A kind of slurry treatment system
The utility model relates to a kind of environment friendly system, especially a kind of slurry treatment system for the treatment of building sewage.
In construction site due to the needs of operation, unavoidably have a large amount of slime waters to produce, at present often the precipitator method are adopted to the process of slime water, namely the large-scale settling tank with certain altitude difference is arranged in order with several, concrete grout is injected high-order settling tank, the object that sandstone is separated with water slurry is reached by drowning oneself of sandstone in water, but this method is taken up an area large, filtration velocity is slow, efficiency is low, tankage reduces gradually along with using, need often cleaning, the concrete grout simultaneously precipitated can solidify at the bottom of pond, add cleaning difficulty, sandstone after solidification in concrete grout cannot reclaim use, certain pollution can be caused to environment.
Chinese invention patent application ZL201410239085.9 discloses a kind of grit water separator, comprise water storage box, sand setting case, filtration unit comprise water storage box, sand setting case, filtration unit, water-in and water outlet, described water storage box and sand setting case link together, the first water outlet is provided with bottom described water storage box, first water outlet is provided with sandboard, described first water outlet is connected with filtration unit, described filtration unit inside sets gradually from top to bottom as filtering layer, buffer layer, adsorption layer and polymeric layer, and filtration unit lower right position is provided with the second water outlet.This grit water separator can reduce the floor space of settling tank to a certain extent, but this grit water separator in use, slime water is not directly carried out water storage box by breaing up, the sandstone that may occur in slime water is not yet separated and is just discharged from water outlet, separating effect is relatively poor, in addition the water be discharged from water outlet, without further process, may cause secondary pollution by environment.
In view of this, the present inventor conducts in-depth research slurry treatment system, then has this case to produce.

Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, the slurry treatment system that the present embodiment provides, the clean water basin 30 comprise the sewage lagoon 10 for receiving slime water, bottom is obconic concentrated bucket 20, being connected with concentrated bucket 20 and deckered stock chest 40 and the pressure filter 50 be connected with deckered stock chest 40.The shaped upper part of concentrated bucket 20 can be arranged according to actual needs, in the present embodiment, concentrates the top of bucket 20 cylindrically, and the inside of concentrated bucket 20 has inner chamber.
The inner chamber upper end of concentrated bucket 20 is provided with the waste pipe 21 vertically placed, the upper end of waste pipe 21 is communicated with sewage lagoon 10 by pipeline, lower end has sewage outlet 22, sewage outlet 22 is dehisced for trumpet-shaped, and sewage outlet 22 is provided with the loose mud plate 23 of tapered shape, this loose mud plate 23 has gap with the mouth rim of sewage outlet, like this, after slime water in sewage lagoon 10 flows into waste pipe 21, first can break up through loose mud plate 23, then enter the inside of concentrated bucket 20 from loose mud plate 23 and the gap of the mouth rim of sewage outlet.
The slime water entering concentrated bucket 20 inside precipitates in concentrated bucket 20, its supernatant liquor is up floating, turbid solution precipitates downwards, and downwards the turbid solution of precipitation becomes underflow with the bucket wall contact flocculation of concentrated bucket 20, then under gravity along the bucket wall of concentrated bucket 20 turbination bottom toward current downflow.
The upper end of concentrated bucket 20 is provided with clear water output 24, clear water output 24 is communicated with clean water basin 30 by pipeline, flow out to from clear water output 24 in clean water basin 30 after the supernatant liquor formed in concentrated bucket 20 is up floating, water in clean water basin 30 is recyclable as water for building, certainly, the water in clean water basin 30 also can make other purposes.
The lower end of concentrated bucket 20 is provided with underflow outlet 25, and underflow outlet 25 is positioned at the apical location of concentrated bucket 20 bottom reverse tapered shape, and is communicated with deckered stock chest 40 by pipeline.The underflow formed in concentrated bucket 20 flows out in deckered stock chest 40 from underflow outlet 25, and then is admitted to pressure filter 50 and dewaters, and forms the dry pulp that can be used again.
Preferably, the mixing module 70 that the slurry treatment system of the present embodiment also comprises dosing tank 60 and is connected with dosing tank 60, dosing tank 60 and mixing module 70 can be conventional parts.Mixing module 70 is connected with sewage lagoon 10 and waste pipe 21 simultaneously, and connecting tube between sewage lagoon 10 and mixing module 70 is provided with the first Pulp pump 11.Like this, slime water in sewage lagoon 10 produces and reacts entering the medicament that can to improve this between waste pipe 21 in mixing module 70 with dosing tank 60, supernatant liquor and turbid solution is separated into through reacted slime water is easier in concentrated bucket 20, meanwhile, the first Pulp pump 11 is used effectively can to prevent line clogging.It should be noted that, the medicament of the interpolation of dosing tank 60 can add according to actual needs, and the medicine added is also conventional medicament, no longer describes in detail herein.
Preferably, in the present embodiment, between clean water basin 30 and sewage lagoon 10, be connected with circulating line 31, circulating line 31 be provided with recycle pump 32.Like this, when the slime water concentration in sewage lagoon 10 is too high, by circulating line 31, the water in clean water basin 30 can be injected sewage lagoon 10 and slime water is diluted, prevent the too high impact of slime water concentration from concentrating the separation efficiency of bucket 20.
Preferably, in the present embodiment, the connecting tube between deckered stock chest 40 and pressure filter 50 is provided with the second Pulp pump 41.The underflow in deckered stock chest 40 is convenient to be transported to operation on pressure filter 50 like this.
