Description
Technical field
The present invention relates to the tap water water treatment field, relate in particular to a kind of integrated treatment process that the rural area exceeds standard and drinks water of handling.
Background technology
In the human body 70%～80%, moisture, the water quality that long-term drinking is bad, can cause that physique is not good, resistibility weakens naturally, then all kinds of diseases and ailments are inevitable, moreover the pollutent of long-term accumulated is when arriving health and can't bear, brilliant again doctor, more effectively medicine probably also difficulty prove effective, so the saying of " king that water is hundred medicines " is arranged.Estimate according to " rural potable water safety and sanitation assessment indicator system ", the aggregate level of China's Rural water supply is not high, and there still have people more than 300,000,000 to drink water to be dangerous, having a strong impact on the masses' healthy and orthobiosis.Because water body is contaminated to be on the rise, particularly organic pollution adopts conventional precipitation, filtration, sterilization only can remove 20% organic pollutant, and therefore, the deep purifying treatment industry of Drinking Water in China obtains flourish under this background.
The deep purifying of water mainly adopts following several mode: charcoal absorption---and the charcoal absorption water purification technology is the high efficiency of additive capability that utilizes gac, removes stink, organism, phenol, alkylbenzene sulfonate, disinfection byproduct (DBP), heavy metal ion and other micro-objectionable impuritiess in the water.Secondary filter---secondary filter is to use accurate filter that water is filtered, and it can be removed the impurity particle scope and look the kind of accurate filter and difference, and accurate filter is commonly used in water treatment candle filter and a pre-filming filter.What the filter core element of candle filter was commonly used is porous ceramics and polypropylene fibre, can remove the particle more than 2～5 microns; Pre-filming filter is commonly used diatomite filtration, before filtering to filter element precoating diatomite form 2～-filter membrane that 3mm is thick, can remove colloidal solid, bacterium, part virus and larger molecular organics.Membrane sepn treatment technology---membrane sepn is a kind of under certain impellent effect, utilizes the through performance of certain films to divide the technology of ion, molecule and impurity in dried up.It has separation efficiency height, no phase transformation, no chemical transformation, simplicity of design, characteristics such as easy to operate and energy-conservation.Membrane technique is a new technology of the research and development fifties.China is applied to sea water desaltination with this technology at first, is used for the preparation (semi-conductor, biology, medicine, beverage, microelectronics) of industrial pure water then.Be used for the preparation of tap water the beginning of the nineties in last century.
China's membrane separation technique is started late, and also is in the infancy at present.The membrane separation technique that with pressure is motivating force has reverse osmosis, nanofiltration, ultrafiltration and micro-filtration.
Wherein: micro-filtration (MF)---micro-filtration accounts for 40%～50% at present on market, and the filter membrane aperture is 0.05～5.00 μ m, and the operation transmembrane pressure is 0.1～0.3Mpa, is suitable for that falling of liquid medium is turbid most, degerming handles, and can remove 10
-6Impurity, greatly reduce the turbidity of water, especially to good iron removal effect.Bacterium detention rate is generally used for producing the end processing of high purity water up to 99.9%.
Ultrafiltration (UF)---ultrafiltration can remove in the water 10
-9(nano level) particulate matter can directly prepare drink water, also can do reverse osmosis, nanofiltration pre-treatment, and the transmembrane pressure of operation is 0.3～1.0Mpa; Ultrafiltration is mainly used in molecular weight removing greater than 6000 larger molecular organics.More than the water handled of two kinds of methods all keep mineral substance and trace element in the water.
Reverse osmosis (RO)---reverse osmosis technology is that industrial sectors such as electronics, medicine, chemical industry prepare one of major technique of pure water.The advanced treatment that is used for tap water in recent years in a large number.The aperture of reverse osmosis membrane about 10
-11～10, can remove in the water almost all materials, comprise various suspended substances, micelle, organism, bacterium, virus, mineral substance, pyrogen etc.
Other treatment processs---as distillation method, electroosmose process, ion exchange method etc.The general treatment process of these methods is relatively complicated, and the cost for the treatment of water is higher.
Therefore, along with the continuous development of membrane science technology, adopting efficient, economic membrane integrating technique purifying treatment brackish water will be an important directions of rural potable water treatment technology Future Development.
Summary of the invention
