Description
Technical field
The present invention relates to a kind of tap water sterilization system based on membrane technique, belong to water-treatment technology field.
Background technology
Tap water refers to the water for people's life, production and application meeting respective standard by producing after water treatment plants purification, sterilization.Domestic water draws rivers and lakes and underground water mainly through the water intake pumping station of water factory, surface water, by waterworks according to " national Drinking Water related sanitary standard ", through the process of the technical process such as precipitation, sterilization, filtration, be transported to each user finally by Energy Saving Measures of Pumping Station.
The life of tap water and people is closely bound up, the water quality of tap water and the health of people in close relations.The water quality standard of China also has a certain distance than international standard at present.Current water supply security is faced with the dual-pressure that the day by day serious and water quality standard of tap water of pollution of waterhead improves gradually, and this also just has higher requirement to advanced water treatment technology.
Traditional water technology mainly takes following technique: extract water source → coagulation → precipitation → filtration → feeding clean water basin and to carry out disinfection → input water supply line.But the pollution of water resources is day by day serious at present, especially heavy metal contamination and Organic pollutants, and according to statistics, earth surface water source about 50% water source of China is polluted, and hundreds of organic compound, heavy metal ion enter water source; There is the phenomenons that exceed standard such as fluorine, arsenic, iron, manganese in underground water source.And the current most waterworks of China still uses traditional water technology, if water source by heavy metal ion and organic compound pollute, so above-mentioned traditional technology just seems unable to do what one wishes.Therefore, be necessary to carry out advanced treatment to water supply.
Although source quality pollutes constantly aggravation, along with the raising of living standards of the people, the quality of tap water is had higher requirement.Come into effect " drinking water sanitary standard " (GB5749-2006) on July 1st, 2007, in new standard, water-quality guideline is increased to 106 by 35 of standard in 1985 for this reason, and the limit value of a lot of index is stricter.New standard emphasis strengthens the control overflow to microorganism, heavy metal and organic pollutant, and basic and international organization and developed country water quality standard integrates with.
Therefore, further guarantee, in order to the healthy and social development of people, be necessary, research and develop a kind of novel running water processing system, this system can carry out advanced treatment by tap water supply, makes the water quality after processing reach the new standard of national regulation.
Summary of the invention
Goal of the invention: the object of the invention is to solve the deficiencies in the prior art, provides a kind of tap water sterilization system based on membrane technique.
Technical scheme: in order to realize above object, a kind of tap water sterilization system based on membrane technique of the present invention, it comprises successively by ozone sterilizer that pipeline connects, former water tank, lift pump, active sand filter, iron-manganese removing filter, activated charcoal filter, water softener, cartridge filter, ultrafiltration apparatus, nanofiltration equipment, ultraviolet sterilizer and aseptic water tank, described former water tank inside is provided with adverse current forming apparatus and filter screen of water tank, described adverse current forming apparatus comprises on two, lower two funnel shaped parts, water stream channel is provided with in the middle of the bottom of described upper hopper shape parts, described lower funnel-shaped part sealed bottom, described filter screen of water tank is positioned at the below of described adverse current forming apparatus, described former water tank is divided into, lower two chambers, the bottom of described former water tank is provided with water outlet, ultraviolet lamp is provided with near described water outlet.
The ozone sterilizer be provided with in the present invention can carry out preliminarily pasteurized germicidal treatment to water source, and before ozone sterilizer is placed on follow-up flocculation sediment, can oxidized metal species, improve coagulation and filtration effect, replace chlorination in the past, reduce the toxic side effect of chlorine, also serve the effect of sterilization simultaneously, Organic substance in water can be oxidized, reduce subsequent disposal difficulty, reduce the effect of pollutent;
The subgravity that the lift pump be provided with mainly realizes former water promotes, and to realize the run by gravity of subsequent treatment process, alleviates the pressure of subsequent processing device;
Be provided with active sand filter, active sand filter is a kind of high efficiency filter treatment unit collecting coagulation, clarify, be filtered into one, and active sand filter is for the flocculation sediment filtration treatment device of routine, and it has the following advantages: filter and run continuously, without the need to shutting down back flushing, efficiency is high; Without the need to backwash pump blower fan punching water tank and valve etc.; Integrate coagulating sedimentation and filter, enormously simplify technical process and take up an area space; Operation and maintenance expense is low; Waste water for high SS content does not need pre-treatment (water inlet SS can reach 150mg/L); Compared with conventional sand filtration process, the chemical agent of 30%-40% can be saved; The device space of 70% can be saved; Depth Filtration can be realized; Filter bed loss of pressure head is little, only has 0.5m; Adopt single homogeneous filtering material, need not grating layer; Filtrate is by continuous wash, and good filtration effect, without first filtrate problem; Stable effluent quality; Be easy to reorganization and expansion;
The iron-manganese removing filter be provided with can except unnecessary ferro element and manganese element in anhydrating, although ferrimanganic has irreplaceable effect in the activity of sustaining life, but for human body, the intake of ferro element every day is only 20 mg, and the content of manganese only has 10 ~ 20 mg in human body, for so micro-ferrimanganic demand, the mankind can be made up by diet completely, in order to suppress high-iron and high manganese too to absorb generation human body being produced to potential hazard, then can remove unnecessary ferro element and manganese element by iron-manganese removing filter;
