Accompanying drawing explanation
Fig. 1 is the air-flotation separation equipment schematic diagram corresponding to the utility model preferred embodiment.
Embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solutions of the utility model are further non-limitingly described in detail.
Shown in Fig. 1, be air-flotation separation equipment, after it is generally arranged on coagulation apparatus (not shown), before biochemical processing device, mainly spend the flco generating after cleaning coagulation, make waste water clean to carry out next step biochemical treatment.From diagram, this air-flotation separation equipment comprise splendid attire waste water air flotation pool 1, make waste water produce bubble air-dissolving apparatus 2, be arranged on the pumping plant 3 between this air flotation pool 1 and air-dissolving apparatus 2 and be arranged on air flotation pool 1, for striking off the mud scraper 4 of scum silica frost; The Scraping device that this mud scraper 4 is well known to those skilled in the art, it can be purlin car formula mud scraper.
Particularly, air flotation pool 1 comprises waste water chamber 10, waste slag chamber 12 and is arranged on gas-floating chamber 11 between waste water Shi He waste slag chamber 12, and wherein the bottom surface of waste slag chamber 12 is inclined-plane.Between waste water chamber 10 and gas-floating chamber 11, being provided with the first dividing plate 20, there is gap with the bottom of air flotation pool 1 in this first dividing plate 20, and the small part waste water in waste water chamber 10 can enter in gas-floating chamber 11 by this gap; Between gas-floating chamber 11He waste slag chamber 12, be provided with second partition 21, this second partition 21 separates gas-floating chamber 11He waste slag chamber 12 completely, and the top of this second partition 21 has certain obliquity, oblique angle size, 10 ° of left and right, can make scum silica frost more easily enter in waste slag chamber 12 like this.At the top of waste water chamber 10, be provided with water entry 30, this water entry 30 is communicated with coagulation basin (not shown) and waste water chamber 10, for influent waste water provides passage; At the middle part of gas-floating chamber 11, be provided with water exit 31, this water exit 31 is communicated with gas-floating chamber 11 and biochemical treatment tank (not shown), for wastewater effluent provides passage; In the bottom of waste slag chamber 12, be provided with slag releasing channel 32, this slag releasing channel 32 is communicated with waste slag chamber 12 and mud storage pool (not shown), for waste residue, slag tap passage is provided, simultaneously, because the bottom of waste slag chamber 12 is inclined-plane, therefore the interior waste residue of waste slag chamber 12 can, in inclined-plane slips into slag releasing channel 32, prevent that waste residue from overstocking.
The bottom of gas-floating chamber 11 is provided with 4 taper sludge buckets 17 that cardinal principle is identical, and be separately positioned on the identical mud discharging pipe 18 of 4 cardinal principles between adjacent conical sludge bucket 17, the quantity of taper sludge bucket 17 is not absolute, its quantity can be determined according to the size of gas-floating chamber 11 in actual applications, only need roughly be paved with the bottom surface of this gas-floating chamber 11, same, the quantity of mud discharging pipe 18 changes according to taper sludge bucket 17.These 4 taper sludge buckets 17 are mainly used in collecting the mud precipitating in waste water, and mud discharging pipe 18 is communicated with mud storage pool, the mud of collecting for transporting taper sludge bucket 17.
Air-dissolving apparatus 2 comprise dissolving 25 and with the interconnective air compressor (not shown) of dissolving 25, air compressor is pressed into air in dissolving 25, waste water fully contacts with air in dissolving, general design pressure is 4kg/cm
2, the residence time of water adopts 3 minutes, and at this moment, in waste water, air content can reach the 50-80% of saturated content.
Pumping plant 3 comprises water pump 8, be arranged on drinking-water pipe 13 between water pump 8 and waste water chamber 10, be arranged on the water inlet pipe 14 between water pump 8 and dissolving 25 and be arranged on dissolving 25 and gas-floating chamber 11 between water shoot 15.Opening part at drinking-water pipe 13 is provided with strainer 27, and when drinking-water pipe 13 extracts waste water, this strainer 27 can larger flco or the waste residue of filtering particle.
The groundwork process of air-flotation separation equipment of the present utility model is, first the waste water after coagulation is input in waste water chamber 10 by water entry 30, enters a part of waste water in waste water chamber 10 gap from the first dividing plate 20 and flows in gas-floating chamber 11; Water pump 8 starts simultaneously, by drinking-water pipe 13 and water inlet pipe 14, the waste water in waste water chamber 10 is input in dissolving 25, and waste water is pressed into after air, then by water shoot 15, the waste water that has mixed air is entered in gas-floating chamber 11; The waste water and the raw wastewater that are pressed into air mix mutually, in gas-floating chamber 11, compared with light flco, are rising to pond face with bubble, and mud scraper 4 is hung into slag thing chamber 12, and heavier flco precipitates, and by taper sludge bucket 17, are collected; Because floating or precipitation have occurred flco, so the waste water at gas-floating chamber 11 middle parts is the most clean, the water exit 31 that is therefore opened in gas-floating chamber 11 middle parts starts waste water to be discharged to subordinate's reaction tank, certainly, also can be back in air-dissolving apparatus 2, carry out secondary and be pressed into air; And the mud entering in slag thing chamber 12 and taper sludge bucket 17 enters in mud storage pool by slag releasing channel 32 and mud discharging pipe 18 respectively.
In sum, the air-flotation separation equipment that the utility model discloses is a kind of multimodal, with low cost, rational in infrastructure, and the good air-flotation separation equipment of waste water cleaning effect.
It is to be noted; above-mentioned preferred embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model spirit change or modify, within all should being encompassed in protection domain of the present utility model.
