Abstract

The utility model relates to a water supply grid-bar clarifier tank, which is characterized in that one end of the pipeline is welded with a two-stage eddy flow flocculating chamber, and the other end is welded with a grid-bar flocculating chamber; the grid-bar flocculating chamber is connected with a contact flocculating chamber by an opening. Simultaneously, an earth water separation region is added with a sloped tube to make the alumen ustum to be gravitationally settled under the laminar flow condition; the alumen ustum is caused not to easily turned upwards; the load rate of the liquid level is improved; the adaptability on the water temperature and the turbidity change is high. The tank needs no machinery equipment; the settling effect is good. The utility model has the characteristics of compact structure, simple operation, low energy consumption, low medicine consumption, energy saving, little investment on specific yield, small needed tank body on specific yield, small ground occupation, etc.

Description

Grid-bar water settling pool

The utility model is to be used to feed water the grizzly bar settling pond.

In the prior art,, be the employing sludge blanket clarifier as the feedwater settling pond, plusator, mechanical accelerating purifying pool, circulatior clarifier.The flocculation operation is to utilize backflow body refuse or suspension body refuse to contact absorption with former water-borne glue body impurity to carry out, and mud-water separation is to sink by alumen ustum gravity under turbulent-flow conditions, and its shortcoming: mud-water separation clear water upflow velocity is all below 1.1mm/Sec; Mechanical accelerating purifying pool needs mechanical stirring and machinery to scrape mud equipment, and running maintenance is cumbersome; Though the circulatior clarifier simple structure, the head energy consumption is big, and the consumption medicine is many, and is relatively poor to water quality, water temperature adaptability, and body refuse refluxes wayward, difficult management; Plusator head energy consumption is big, and it is relatively poor that water quality, water temperature, the water yield are changed adaptability, and the recurrence interval is difficult to control, and bookkeeping requires high; Sludge blanket clarifier changes relatively sensitivity to water quality, water temperature, and treatment effect is stable not as good as accelerating purifying pool.

The utility model purpose exactly in order to overcome above-mentioned shortcoming, designs a kind of flocculation neither by the non-again novel flocculation of being undertaken by the suspension body refuse of circulation body refuse, add inclined tube simultaneously and make the alumen ustum grizzly bar settling pond that gravity sinks under laminar flow condition in the mud-water separation district.

The grizzly bar settling pond is seen Fig. 1, Fig. 2, mainly by water inlet pipe (1), twin-stage eddy flow flocculating chamber (2), grizzly bar flocculating chamber (3), multilayer grizzly bar (4), contact flocculation chamber (5), honeycomb (6), inclined tube (7), many water legs (8), rising pipe (9), shore pipe (10) (11) (12) is formed, pipeline one end welding twin-stage eddy flow flocculating chamber (2), the other end welding grizzly bar flocculating chamber (3), with with the aperture grizzly bar flocculating chamber (3) with touch flocculating chamber (5) and be connected, shore pipe is by center shore pipe (10), bucket shore pipe (11), perforated sludge discharge pipe (12) is formed, twin-stage eddy flow flocculation+grizzly bar flocculation+contact flocculation chamber (2) is taken in flocculation, the water that comes out flows into bottom, grizzly bar flocculating chamber (3), multilayer grizzly bar (4) flocculation back water body, upset flows into contact flocculation chamber (5) again, the water floating that makes progress is entered the inclined tube (7) of mud-water separation again by honeycomb (6) rectification, the primary water that comes out from the inclined tube top overflows to the water leg (8), clear water flows to rising pipe (9) again and locates outflow in the many water legs, heavy mud behind the water of clarification source, by center shore pipe (10), bucket shore pipe (11), perforated sludge discharge pipe (12) is discharged termly.

Grizzly bar flocculation (reaction) chamber is the multilayer grizzly bar, under the first lattice the first layer grizzly bar void tower, is provided with shore pipe, the alumen ustum that discontinuity is discharged source water medium coarse sand grain and avaled, and grizzly bar flocculation lattice number is got the 3-4 lattice, and every grid layer is the 4-9 layer, wadding well stream speed V ₂Be 0.02-0.08M/Sec, cross grid current speed V ₁Get 0.24-0.35M/Sec, flocculation reaction total time is 15-20min, grizzly bar flocculation ∑ GT=1.25-1.33 * 10 ⁴Establish inclined tube from underwater 1000mm place, the alumen ustum group contact flocculation that the alumen ustum that avales from inclined tube is direct and the grizzly bar flocculator comes out, after the cluster alumen ustum avales, discharged by sludge bucket and bottom perforated shore pipe, the clear water zone upflow velocity is more than the 2.0mm/Sec, and flow velocity is 2.66mm/Sec in the inclined tube, inclined tube reynolds number Re=19-20, liquid level load 7.2M ³/ m ²/ h.

The utility model is to turn on a kind of alumen ustum is difficult for, and the liquid level rate of load condensate improves, and strong to the variation adaptability of water temperature, turbidity, there is not mechanical means in the pond, the grizzly bar settling pond that sedimentation effect is good, its compact construction, simple to operate stable, the head power consumption is little, the medicine consumption is few, energy-conservation, the specific yield less investment, the Chi Tixiao that specific yield is required, characteristics such as floor space is little.
