Abstract
The present invention relates to one kind of waste water treating apparatus, in which fine calcium carbonate particle treated through high temperature is made to mix with waste water, waste water is reacted with CO2 in a gas-water convection coagulator, and the waste water is then clarified, drained and calcium carbonate separated for reuse. The waste water treating apparatus operating on calcium carbonate treatment has small size, high treating speed, low cost and other advantages.
Description
The present invention relates to the environmental protection field, is a kind of device of purifying liquid waste.
Along with the raising of industrial expansion and people's living standard, waste water is more and more at present, and serious environment pollution has restricted economic growth.Improvement waste water is extremely urgent, and people have utilized various effective means, technology that waste water is handled.But numerous and diverse changeable, the condition such as floor space is big, the treatment time is long, investment and running cost height, effect are undesirable of, treatment system many because of kind of waste water can not finely be implemented.
In order to address this problem, overcome above-mentioned defective, we design a kind of waste water disposal facility., by certain technology pollutants in waste water is separated with calcium carbonate microparticle, be converted into innoxious substance, make waste water be purified discharging or recycle.
The objective of the invention is to design and a kind ofly handle waste water technology, the separated from contaminants of waste water is come out, reach the purpose of purification with calcium carbonate coagulating.This system device is simple, easy to operate, raw material sufficiently is easy to get, low price, the treatment time is short, floor space is little, be not subjected to temperature limitation (above zero), in numerous purification of waste water processing technology field, calcium carbonate coagulating is ideal, simple and efficient wastewater processing technology.
The object of the present invention is achieved like this, and calcium carbonate microparticle (2mm) is added from the high temperature furnace roof, revolves skew wall by the Luo in the High Temperature Furnaces Heating Apparatus (1500 degree-1700 degree) and slowly slide to the furnace bottom outlet down, becomes granular high temperature oxidation calcium.High temperature oxidation calcium is with positive charge molecules group glue nuclear, be added in the general how electronegative waste water of PH=2～14, absorption, compression, the small suspended substance of flushed zone negative charge, solute make in the waste water small suspended substance, solute take off steady or change the interionic structure, coalescent and come-up or sink.In coalescent and sinking process, the calcium hydroxide that calcium oxide is hydrolyzed into gradually, the carbon dioxide that produces and reclaim with the lime carbonate heat, convection current contact in filling the air water convection current coagulator of netted cleaning ball, combination reaction takes place, generate lime carbonate with sinking agglomerated thing coprecipitation, make waste water obtain clarification and recycle or oxygenating discharging.Again the lime carbonate in the throw out is separated, reheated into the recycling of high temperature oxidation calcium.
Wastewater processing technology of the present invention, equipment is simple, only needs to build a High Temperature Furnaces Heating Apparatus (coal gas and natural gas heating), mixing pit, air water convection current coagulator, settling pond on the ground with brick.Magnitude range can be decided according to handling wastewater flow.This facility has less investment, instant effect, characteristics that running cost is low, and the waste water cost of handling 1000 kilograms is between 0.1～0.3 yuan.The waste water of handling reaches national secondary discharge standard.This technology can be effected a radical cure various wastewater.The boiling waste water of paper plant for example, the alkali content height after carrying out individual curing with calcium carbonate coagulating, contains the alkali clear water and can directly be circulated in boiling, also can economize on alkali number.The calcium oxide that this treatment system is used is few, refines calcium oxide every day and gets final product for 1～2 ton as handling 5000 tons of required High Temperature Furnaces Heating Apparatuss of waste water every day.
The description of drawings of the calcium carbonate coagulating technology for treating of waste water of the present invention, accompanying drawing are plan view.As scheme institute and look: 1. induced draft fan.2. High Temperature Furnaces Heating Apparatus.3. lime carbonate grain storehouse.4. mixing pump.5. calcium oxide.6. waste water.7. carbonic acid gas.8. mixing pit.9. air water convection current coagulator.10. settling pond.11. primary water.12. blowdown separates lime carbonate.
Concrete structure of the present invention is provided by following examples and accompanying drawing thereof: calcium carbonate microparticle (3) is added in the High Temperature Furnaces Heating Apparatus (2), lime carbonate (3) generates calcium oxide (5) through high temperature, mixing pump (4) is sent in the mixing pit (8) after waste water (6) and calcium oxide (5) break-in are stirred, after mixing, send in the air water convection current coagulator (9), the carbonic acid gas (7) that High Temperature Furnaces Heating Apparatus (2) produces enters air water convection current coagulator (9) through induced draft fan (1), take place to flow into settling pond (10) after the combination reaction, generate clear water (11) above and discharge, below blowdown separate lime carbonate (12) and return High Temperature Furnaces Heating Apparatus (2) recycle.
Claims (1)
- A kind of calcium carbonate coagulating treatment unit of waste water, be characterized in integral combined, mainly make raw material by calcium carbonate microparticle (3), in High Temperature Furnaces Heating Apparatus (2), generate calcium oxide (5), under the effect of abrasive dust mixing pump (4), and waste water (6) stirs, enter the carbonic acid gas (7) of mixing pit (8) and process induced draft fan (1), after dividing two through air water convection current coagulator (9) chemical combination, flow into settling pond (10) clarification, flow out clear water (11) above, below blowdown separate lime carbonate (12), return High Temperature Furnaces Heating Apparatus (2) recycle.
