Description
Technical field
The utility model relates to sewage disposal, and specifically a kind of carbonic acid gas mineralising emission-reduction technology is processed the device of high hardness water cleansing and recycling.
Background technology
Carbonic acid gas (CO2), as greenhouse gases, is the main arch-criminal of global warming.Due to industrial fast development, mass energy is consumed, the quantity discharged of carbonic acid gas also constantly increases, report according to International Energy Agency (IEA) in 2009 issue, the quantity discharged of global carbonic acid gas in 2007 has reached 29,000,000,000 tons, China's CO2 emissions is 6,000,000,000 tons, accounts for 21% of whole world discharge, and having surpassed the U.S. becomes the first big country of energy-related Carbon emission in the world.In recent years, the extreme weathers such as snow disaster, extremely hot, heavy rain frequently occur, the huge disaster that Greenhouse effect bring is just being born in the whole world, in the face of severe environment situation like this, how to reduce the discharge of carbonic acid gas, more effectively alleviate Greenhouse effect, become the difficult problem that major issue urgently to be resolved hurrily and countries in the world face.
At present, for the processing of extensive carbonic acid gas, mainly contain geological storage, seal up for safekeeping ocean and three kinds of methods of carbonic acid gas mineralising.The carbonic acid gas mineralising refers to utilizes alkalescence and basic oxide to react with CO2, thereby generates the process of stable compound stabilizing carbon dioxide.Carbonic acid gas mineralizer carbonate compound can be at occurring in nature stable existence more than one thousand years, be stablize, the method for safe stabilizing carbon dioxide.At present, domesticly for the selected raw material of carbonic acid gas mineralising, be mainly Magnesium Silicate q-agent (MgSiO4), Calucium Silicate powder (CaSiO3) compounds, this class material is large at the occurring in nature storage capacity, and it is stronger that alkalescence is compared other metallic compounds.But because existing carbonic acid gas mineralising does not have the high added value product, make the economy of CO2 mineralisation process lower, therefore how to utilize the Chemicals of carbonic acid gas mineralisation process production high added value simultaneously, making the CO2 mineralising seal up for safekeeping and realize economically feasible, is that current CO2 mineralising realizes industrialized bottleneck.
China belongs to the country of shortage of water resources, along with the outbreak at full speed in each field such as industrial, agriculture, the demand of water resources is also sharply increased, thereby causes rivers cutout, minable groundwater resource fewer and feweri, and industry, agricultural water cost are more and more higher.Along with water resources shortage, the supply of water has become the enterprise expanding restraining factors.
Industrial Wastewater Treatment is for guaranteeing to reach emission standard, often add the treatment agents such as superfluous lime, saliferous is high afterwards, hardness is high to cause processing, is directly used in the agricultural irrigation meeting and causes salting of soil, can cause its uses of negative impact such as fouling, obstruction for industry, often directly discharge.In the prior art, the method for middle water reuse is that not only the capital construction cost compare is large for this technique by biological treatment+precipitation+filtration, and treatment effect is not fine, the Reuse Range of water in impact, the operability of this technique is also poor simultaneously, needs to control the effect of biological treatment.
Summary of the invention
The purpose of the utility model patent is to overcome the deficiency of above-mentioned technology, provides a kind of carbonic acid gas mineralising to seal the device that softening high hardness water desalination is processed simultaneously up for safekeeping, will process water and carry out reuse, substitutes primitive water.
The technical solution of the utility model is: a kind of carbonic acid gas mineralising technical finesse high hardness water device for cleansing and recycling: it comprises except hetero moiety, digestion clarification part, mineralising part and filtration fraction;
The described hetero moiety that removes comprises reuse pool, lift pump and absorption neutralization reactor, and the pipeline between described lift pump and absorption neutralization reactor is provided with chemicals dosing plant;
Described digestion fining end divides and comprises digestive shelf, surface filter, lime mud storage tank and intermediate pool;
Described mineralising part mainly consists of the mineralising reactor, and the water-in of described mineralising reactor is communicated with by pipeline and intermediate pool, also is provided with fresh water pump therebetween; The water outlet of described mineralising reactor is communicated to strainer;
Described filtration fraction comprises strainer, clean water basin and fresh-water pool; The clear water output of described strainer is linked clean water basin, and the sludge outlet of strainer is communicated to the chemicals dosing plant on absorption neutralization reactor inlet pipeline.
Described lime mud storage tank web plate paper blotter press, whizzer or pressure filter.
Described surface filter can replace with thickener or filter.
Described strainer can replace with surface filter or thickener.
The beneficial effects of the utility model have following aspect:
(1) adopt powerful purification techniques, this is the first step of processing the key of reuse.Organic object height in water inlet, and many colloidalmaterials are arranged, must remove, the specific equipment of removal is the absorption neutralization reactor, it is that the collection medicament fully mixes with the high speed of water; Suitable flco growth environment; Three functions of solid-liquid high efficiency separation are integrated, and utilize column plate to produce " eddy current " microkinetic by current, and the utmost point is beneficial to flco absorption impurity, adds common flocculation agent and the lime that a small amount of value is low to carry out sewage disposal, can reach the deep purifying effect.
(2) adopt carbonic acid gas mineralising deep desalting technology.Utilize Ca in high hardness water
2+, Mg
2+particle mineralising carbonic acid gas, fixedly sequestration of carbon dioxide simultaneously, is deviate from salt in water.Adopt this device ratio of desalinization can reach 80 ~ 90%, more valuable is that the water rate of recovery is high, and it is 60 ~ 70% that general film reclaims the sewage disposal rate of recovery, and device sewage recycle-water rate of the present utility model can reach more than 80%.
