Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.

Refer to Fig. 1, this utility model provides a kind of technical scheme: a kind of sewage-treatment plant, including bottom be the cylinder 10 of inverted cone, it is arranged on filter sand 50 and the inlet channel 13 excessively within cylinder 10, the arranged outside of described cylinder 10 has blow-off line 11, cylinder 10 be arranged below compressed air inlet pipe 14, cylinder 10 center of inside is provided with rhombus water-locator 20, riser 30 and wash husky device 40, it is internal that water-locator 20 was arranged on filter sand 50, water-locator 20 is fixing with the bottom of cylinder 10 to be connected, the upper end of water-locator 20 is provided for the upper installing hole 21 of riser 30 turnover, the lower end of water-locator 20 is provided for the lower installing hole 22 of riser 30 turnover, water-locator 20 be internally provided with die cavity 25, the side of water-locator 20 is provided with the water inlet 23 connected with die cavity 25, water inlet 23 connects with inlet channel 13, the surface of water-locator 20 is provided with multiple outlet 24 connected with die cavity 25, the underface of water-locator 20 is provided with truncated cone-shaped collection sand tube 31 and high pressure nozzle 16, high pressure nozzle 16 is arranged on the underface of collection sand tube 31, it is provided with gap between collection sand tube 31 and high pressure nozzle 16, compressed air inlet pipe 14 connects through the bottom of cylinder 10 with high pressure nozzle 16, threadeds through upper installing hole 21 and lower installing hole 22 with collection sand tube 31 in the lower end of riser 30, described sand device 40 of washing includes sand developing tube 41 and vertical lower sand developing tube 42 on reverse frustoconic, and upper sand developing tube 41 is integral type structure with lower sand developing tube 42, lower sand developing tube 42 is arranged on the top of water-locator 20, upper sand developing tube 41 is fixing with the top of cylinder 10 to be connected, the top of riser 30 is arranged on the inside of sand developing tube 41, riser 30 and wash and be provided with gap between husky device 40, the inwall of lower sand developing tube 42 is provided with the first helical blade 43, the outer wall upper end of riser 30 is provided with second helical blade 32 highly identical with the first helical blade 43, between second helical blade 32 and the first helical blade 43 interlaced and be provided with gap, the upper end of upper sand developing tube 41 is provided with sewage draining exit 411, the sewage draining exit 411 place plane top higher than riser 30 and the top lower than cylinder 10, sewage draining exit 411 connects with blow-off line 11, the top of cylinder 10 is provided with discharge outlet 12, and discharge outlet 12 is arranged on the outside of sand developing tube 41, described cylinder 10 be arranged below spike 15, the top of a spike 15 is fixed with cylinder 10 and is connected.

In order to prevent filter sand 50 from entering into die cavity 25 from outlet 24, described outlet 24 be shaped as truncated cone-shaped, the inner bottom surface diameter of outlet 24 is more than the outer bottom diameter of outlet 24. The inner bottom surface of outlet 24 refers to the bottom surface being connected with die cavity 25, and the outer bottom of outlet 24 is and crosses the face that filter sand 50 contacts. The water that truncated cone-shaped outlet 24 is also more conducive in die cavity 25 discharges.

For preventing filter sand 50 from entering into sewage draining exit 411, being provided with the drainage screen 44 being completely covered by sewage draining exit 411 in described upper sand developing tube 41, drainage screen 44 is connected by screw is fixing with the inwall of upper sand developing tube 41. For ensureing that riser 30 and water-locator 20 are tightly combined, filter sand 50 was avoided to enter into die cavity 25 from the gap between riser 30 and upper installing hole 21 or between riser 30 and lower installing hole 22, for matched in clearance contact compression between described riser 30 with upper installing hole 21, for matched in clearance and contact compression between riser 30 with lower installing hole 22.

With water pump, from inlet channel 13, treatment sewage being delivered to water-locator 20, rhombus water-locator 20 and the contact area crossed between filter sand 50 bigger, water distribution better effects if, thus improving sewage treating efficiency, sewage is slowly to rise bottom filter sand 50 excessively to upstream direction, and the sand bed crossing filter sand 50 started the dirt drainage from bottom, so that bottom is crossed filter sand 50 and concentrated substantial amounts of impurity gradually, simultaneously, in the compressed air inlet pipe 14 being connected with source of the gas, substantial amounts of high pressure air is from the ejection gases at high pressure of high pressure nozzle 16 constant flow, gases at high pressure make the filter sand 50 of crossing of bottom be raised along riser 30, the filter sand 50 of crossing with impurity mentioned mixes the sewage through preliminary treatment and rises to from middle riser 30 and wash husky device 40, in this process, cross filter sand 50 and water is fully contacted, owing to crossing the interaction of power between filter sand 50 and water, create a large amount of bubble, solid impurity particulate matter is wrapped up in attached by bubble, cross filter sand 50 and fall back to the layer of sand top of filter sand 50 from slit between lower sand developing tube 42 and riser 30 because of action of gravity, cross filter sand 50 constantly to roll on the first helical blade 43 and the second helical blade 32, rinse, impurity on filter sand 50 was cleaned. on reverse frustoconic, sand developing tube 41 reduces from riser 30 top crossing while the filter sand 50 resistance during falling lower sand developing tube 42 out, and what increase sand developing tube 41 washes husky space, improves and washes husky efficiency. and owing to there is liquid level difference between sewage draining exit 411 and discharge outlet 12, make bubble, some sewage of solid impurity particulate matter is discharged from sewage draining exit 411, after process, clean water flows out from discharge outlet 12 and proceeds to next link, so, 1 workflow of this sewage-treatment plant completes, and periodically runs with this.

While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, being appreciated that when without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, amendment, replacement and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
