Description
Technical field
The utility model relates to a kind of airfloat equipments for sewage treatment more particularly to a kind of high-concentration sewage to handle gas
Floating apparatus.
Background technique
In water supply and drainage treatment process program, solid and liquid separation technology and its equipment are one of key projects.Conventional air bearing
It is mainly used in suspended material similar in partition density and water, and in the poor wastewater treatment of suspended substance sedimentation performance.
Conventional air bearing main operational principle be by air and water certain pressure and under the conditions of, make gas to the utmost
It dissolves in water, then pressure dissolving gas water is formed by by being arranged in the indoor dissolved air release discharge of contact, rapidly generates
A large amount of microbubble.These microbubbles are covered with contact chamber and form similar milk the same " plain boiled water ".Sewage is in flocculant and coagulation
" floccule body " is generated under the chemical action of agent is commonly called as " alumen ustum "." floccule body " is mixed as water flow flows into inside flotation tank body
Room is mutually bonded into " being stained with gas wadding body " (wadding body outer surface is stained with bubble) with a large amount of microbubble herein, and apparent density is small
Yu Shui, " being stained with gas wadding body " rise to the water surface quickly, and suspended matter is polymerized to dross in liquid level knot, and dross scrape collection and has reached solid-liquid
Isolated purpose.Its surface loading of conventional load air bearing can accomplish 2~7M3/M2/h.So conventional air bearing design 100 tons/
Outer dimension reaches 10000 × 3800 when throughput per hour, has reached the limit of transport, can not do again greatly, according to design
In its Disengagement zone of specification length-width ratio reach 1:2 be even up to 1:3 Disengagement zone tail end dissolved air water seldom even without.So going out
Water treatment efficiency is also poor.Conventional daf efficiency is low, and outlet effect is poor, can only accomplish 100 ton/hours, and the air bearing more than the value is set
It is standby to be transported due to oversized.The conventional enterprising aqueous suspension density of air-flotation process ability within 1000 milligrams/L,
Pollutant concentration is more than that this value cannot reach 100 ton/hours for the treatment of capacity in water inlet, be reduced only by 60~70 tons/it is small
When.
In the market, flow is more than 300 ton/hours to industrial wastewater at present, and water inlet suspended matter is more than the waste water of 3000 milligrams/L
Very much, conventional air bearing needs to configure 4 100 ton/hours of air bearing, to increase cost and the land occupation face of sewage disposal device
Product, therefore, it is necessary to research and develop a kind of processing flow at 300 ton/hours or more, suspended matter of intaking is more than the efficient molten of 3000 milligrams/L
Gas air bearing and volume is in 11000 × 3800 transportable air bearings, to substitute conventional air bearing.
And currently, the factor for influencing conventional air-flotation process ability includes the dosing method of flocculant and coagulant, routine is negative
Hybrid reaction area of the sewage outside flotation tank body completes chemical reaction, reaction product namely " flocculation when its work of lotus air bearing
Body " is transported in contact chamber by structural members such as pipelines, and " floccule body " and micro-bubble interaction are bonded in contact chamber
It is formed together " being stained with gas wadding body ".Micro-bubble is bonded in outside the body of " floccule body " during this.The number of bubbles of bonding
Amount and strong degree are determined by the ingredient of water quality and medicament.So different quality has different-effect.Because " floccule body " particle is big
Small difference is larger, and particle ascent rate speed differs greatly, and the apparent density variation for therefore " being stained with gas wadding body " is very greatly.Some is quickly
It floats, some is very slow.In addition the bubble that turbulent water can allow " being stained with gas wadding body " external in Disengagement zone falls off again, causes wadding body
As water flow flows out in water body.So that water outlet is deteriorated, the processing requirement of owner is not achieved.
In view of the above shortcomings, the present inventor, is actively subject to research and innovation, it is a kind of new structural highly concentrated to found
Sewage treatment air flotation equipment is spent, makes it with more the utility value in industry.
