Description
Technical field
The invention belongs to field of water treatment equipment, be specifically related to a kind of method removing subsoil water temporary hardness and device thereof.
Technical background
Subsoil water is the important drinking water source with high-quality of China resident.Big and medium-sized cities mainly include river, lake, reservoir etc. due to water consumption big and commonly used surface water water source earth surface water source, it is characterized in that hardness is low, but suspended impurity is many, Organic substance and antibacterial are many, water processes relative complex, and be vulnerable to impact and the pollution of external environment, and using subsoil water as city alternate source.Compared to surface water, it is few that subsoil water has suspended impurity, and Organic substance and antibacterial are few, and water processes relatively easy, and is not easily susceptible to impact and the pollution of external environment, in small and medium-sized cities, the commonly used groundwater source in town and rural area.
Subsoil water ubiquity hardness and the high problem of temporary hardness (incrustation scale).Incrustation scale is formed by temporary hardness in the process of boiling water, i.e. carbonate hardness, it it is a part for total hardness, be equivalent to heavy carbonate and a small amount of carbonate are combined in water calcium, hardness that magnesium is formed, when water boil, calcium, magnesium heavy carbonate decompose generate precipitation thus reducing hardness of water, it is possible to remove part hardness by the method boiled.If calcium and magnesium mainly exist with forms such as sulfate, nitrate and chlorides in hard water, it is permanent hardness.
Incrustation scale causes the aesthetic difference of drinking water more, to resident living with healthy there is potential impact.Although in China's " drinking water sanitary standard ", the total hardness of regulation water must not exceed 450mg/L, but temporary hardness does not limit regulation.A large amount of HCO existed in the surface water of karst3 -And CO3 2-, there is a large amount of precipitation and floating thing, causes that turbidity raises, part water turbidity is more than 5NTU, and this and Drinking Water in China about turbidity and must not have visible regulation contradiction in water in ion after boiled.China's " drinking water sanitary standard " formulates at reference WHO and western developed country relevant criterion, it formulates foundation is drink unboiled water, and often drink to boil water with China resident and differ greatly, the former mainly drinks the calcium of dissolving, magnesium ion, what China resident drank is that part ion is converted into calcium carbonate, and normal person is affected not clear by long-term drink high carbon acid calcium water.Often do not quote the people of hard water once long-term drink hard water, then there will be malaise symptoms, cause diarrhoea and gastrointestinal function disorderly, namely so-called " being not acclimatized "；Doing washing with hard water, soap foams few, causes waste；With the hard water cooking flesh of fish, vegetable, the nutritive value of food can be reduced because not easily boiling；Wash hair with hard water, hair can be made to cohere, embrittlement etc..
The technology processing high hardness water at present mainly has medicament tenderizer, ion exchange and film tenderizer.Medicament tenderizer is applicable to the little situation of water consumption, runs high expensive when water consumption is big, due to add chemical substance make water application be greatly limited.Ion exchange softening method complex process equipment, it is necessary to consuming substantial amounts of acid or salt is cooked regenerative agent, cost is of a relatively high.Film tenderizer running medium power consumption is relatively big, and water producing cost is higher.Ion exchange and film tenderizer are required for relatively complicated preprocessing process, and to alleviate resin or membrane material contamination in main process, ion exchange makes in water sodium ion etc. increase.
Existing softening technology processing cost is high, is badly in need of a kind of economy and goes subsoil water incrustation scale technique.The earth surface water source total hardness satisfied " drinking water sanitary standard " that China is common, but the dissatisfied complaint of the masses that incrustation scale causes is common, existing treatment technology, need to build complicated and huge process system in water factory, and processing cost is high.And show that human body is not made significant difference by dissolving calcium magnesium ion from existing achievement in research, seek to remove economically the technology of subsoil water incrustation scale, calcium carbonate potential problems are drunk for raising drinking water sense organ and elimination extremely important, up to the present both at home and abroad about drinking water hardness treatment research, focus primarily upon total hardness and reduce in technique, and incrustation scale and temporary hardness research is rare, without maturation process and equipment.Therefore the present invention puts forth effort on and seeks a kind of simple, and the quite cheap processing method of cost removes temporary hardness.
Summary of the invention
Big for current drinking water temporary hardness, the problem of easy fouling, it is an object of the invention to provide a kind of method removing subsoil water temporary hardness and device thereof, from removing HCO water3 -And CO3 2-Angle set out, reduce the temporary hardness in water, reduce the generation of incrustation scale, and utilize air with CO2The water mixing of gas, makes the air bubble of generation by the CO in water2Gas takes the water surface out of.
In order to realize above-mentioned task, the present invention takes following technical solution:
A kind of method removing subsoil water temporary hardness, obtains former water and mixed in hydrochloric acid dissolved with CO2The water of gas, dissolved with CO2The water of gas and air carry out mixing wastewater with air and obtain the water containing tiny air bubble, and the tiny air in water steeps and the CO of dissolving in water2Gas combines to emerge and makes CO2Escape into the CO in water in air with tiny air bubble2Gas is removed.
Concrete, dissolved with CO2The water of gas and the mixed volume of air are than for 1:6.
More specifically, the diameter of described tiny air bubble be sized to 0.5～5mm.
