Abstract

The invention discloses a method and structure for removing turbidite in surface water and reducing temporary hardness in a synergetic mode. The structure solves the problems that sediment, scale and the like are generated after surface water in karst regions is boiled, and meanwhile the turbidite removal function is achieved. A grid flocculation basin and an inclined pipe sedimentation pool are arranged on the front section of the structure. Water discharged out of the inclined pipe sedimentation pool directly enters the acid (HCl) addition reaction section, dissolved CO2 is generated after hydrochloric acid reacts with HCO3- and CO32- in water, water containing dissolved CO2 enters an aeration tank, and aeration heads generate a large number of tiny bubbles which can be combined with CO2 dissolved in water and float out of the water surface so that CO2 can escape into air; meanwhile, tiny turbidite which does not precipitate in the inclined pipe sedimentation pool adheres to the tiny bubbles, and therefore turbidite rises to the water surface to be collected to a residue collection groove through a residue scraper and is then discharged. By means of the structure, a structure cell body is reduced by controlling the reaction precipitation time, lands are saved, and capital construction expenses are reduced; the principle is simple, operation is convenient, and a very high water scale removal rate is achieved for surface water with high temporary hardness.

Description

The method of turbidity and temporary hardness and structures thereof in a kind of collaborative removal surface water
Technical field
The present invention relates to the structures of turbidity and temporary hardness in a kind of collaborative removal surface water.
Technical background
China is vast in territory, and landforms are varied, and the water quality flowing through different landforms place surface water is different.Karst landform refers to solublerock (carbonatite, sulfuric acid rock salt, halogen rock etc.) based on chemical corrosion, and flowing water erosion, gravity to be collapsed etc. and act as the special geomorphology that auxiliary geologic function formed.The distribution of Karst In China landforms is wide, area is large, and account for about 13% of total area, wherein maximum with Guangxi, Guizhou and Eastern Yunnan area occupied, the soil of Guizhou Province more than 70% is karst landform.
A large amount of undissolved suspended matter, colloidalmaterial and microorganism is equally there is in karst region surface water with other regional surface water of China.Simultaneously, it is higher for flowing through earth's surface, karst region water hardness, its hardness formation mechenism is that the carbonatite of indissoluble is under water and carbonic acid gas effect, the bicarbonate ion and the free metal ion (mainly calcium ion and magnesium ion) that generate solubility move in water by rock, current itself have and wash away corrosion, they often becoming the rock of block to be processed into particulate, accelerating the corrosion of rock, thus adding water hardness.Because carbonatite and river exist in a large number in karst region, the corrosion phenomenon of rock is extensively occurred, this is also the major cause that river, karst region hardness content is high.Incrustation scale is formed by temporary hardness in the process of boiling water, i.e. carbonate hardness, it is a part for total hardness, be equivalent to hydrocarbonate and a small amount of carbonate are combined in water calcium, hardness that magnesium is formed, when water boil, the hydrocarbonate of calcium, magnesium decomposes generation precipitation thus reduces water hardness, can remove part hardness by the method for boiling.If calcium and magnesium mainly exist with forms such as vitriol, nitrate and muriates in hard water, be permanent hardness.
Incrustation scale causes the aesthetic difference of drinking water more, to resident living with healthyly there is potential impact.Although the total hardness of regulation water more than 450mg/L, must not limit regulation to temporary hardness in China's " drinking water sanitary standard ".A large amount of HCO existed in the surface water of karst region 3 -and CO 3 2-, there is a large amount of precipitation and floating matter after boiled, cause turbidity to raise in ion, part water turbidity is more than 5NTU, and this and Drinking Water in China are about turbidity and must not have visible regulation contradiction in water.China's " drinking water sanitary standard " is formulating with reference to 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 calcium, the magnesium ion of dissolving, what China resident drank is that part ion is converted into calcium carbonate, and long-term drinking high carbon acid calcium water affects not clear on normal people.The people often not quoting hard water once long-term drinking hard water, then there will be malaise symptoms, causes diarrhoea and functions of intestines and stomach disorder, i.e. so-called " not acclimatized "; With hard water laundry, soap foams few, causes waste; With the hard water cooking flesh of fish, vegetables, the nutritive value of food can be reduced because not easily boiling; With hard water hair washing, can make that hair coheres, embrittlement etc.
The technology of current process high hardness water mainly contains Medicine soften, ion exchange method and film tenderizer.Medicine soften is applicable to the little situation of water consumption, when water consumption is large run high expensive, due to add chemical substance make water application be greatly limited.Ion exchange softening method complex process equipment, need a large amount of acid of consumption or salt to cook regenerator, cost is relatively high.The consumption of film tenderizer operational process medium power is comparatively large, and water producing cost is higher.Ion exchange method and film tenderizer all need comparatively loaded down with trivial details preprocessing process, and to alleviate the pollution that in main process, resin or mould material are subject to, ion-exchange makes the increase such as sodium ion in water.
Existing softening technology processing cost is high, is badly in need of a kind of economic removal karst region surface 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, and existing treatment technology, need build complicated and huge treatment system in water factory, processing cost is high.And show that solubilize calcium magnesium ion does not make significant difference to human body from existing achievement in research, seek the technology processing karst region surface water incrustation scale economically, calcium carbonate potential problems are drunk for raising this area's drinking water sense organ and elimination extremely important, up to the present domestic and international about tap water hardness treatment research, mainly concentrating on total hardness reduces in technique, and to incrustation scale and temporary hardness research rare, without maturation process and equipment.Therefore the present invention puts forth effort on and seeks a kind of simple, and the quite cheap treatment process of cost removes temporary hardness, can work in coordination with simultaneously and remove turbidity in water.
