Description
Technical field
The present invention provides a kind of and surpasses/the micro-filtration water-purifying apparatus, specifically a kind of water-saving ultra/micro-filtration water-purifying apparatus that is applied in the drink water purifying process.
Background technology
In recent years, along with the industrialized process of China, environmental pollution problems is increasingly serious.The seriously polluted life that is threatening the mankind of modern society's water resources; United Nations's health organization gives a warning to the whole world: " 21 century; water resources crisis will be the human fact that at first will face ", " whole world has at least people more than 50,000 to die from because of drinking the various diseases that polluted water causes every day ".Scientist reminds us: if or else we note the maintenance to water resources, will occur--and " water on the earth be everywhere, but one could not be drunk! "
Along with constantly bringing forth new ideas of technology, membrane technique has become core technology, especially ultrafiltration and the micro-filtration that the countries in the world water treatment field is paid close attention to, is widely used in the drinking water treatment field.After particularly new drinking water standard came into effect, conventional art can not satisfy the requirement of new standard, and therefore traditional water factory all will undergo technological transformation, and used the ultrafiltration and the microfiltration membrane technology that more generally are acknowledged as green technology.
But in practical application, ultrafiltration and microfiltration membrane system need regularly be carried out back flushing, carry out once in general per 15～60 minutes; Produce a large amount of backwash water thus; General in addition ultrafiltration and micro-filtration have two kinds of filter types: dead-end filtration and cross flow filter, the pollutent that all tunicles of dead-end filtration are held back are all attached to film surface, the pollution speed of having aggravated film; Therefore application at present more is a cross flow filter; But cross flow filter can produce a part of condensed water, and the ratio of general condensed water accounts for 10～20%, and the recovery of the water of therefore present surpassing/micro-filtration water-purifying apparatus is generally 75%～90%.Remaining 10～25% all can enter near water body or enter municipal sewage pipe network.No matter choosing which kind of discharging modes, all is a kind of waste for the water resources that is becoming tight day.If take recycling can practice thrift great amount of water resources to membrane-concentrated water and backwash water, and can reduce wastewater discharge, improve the water recovery of film system.The present both at home and abroad also rarely found relevant report that has membrane-concentrated water and backwash water to recycle has ordinary method such as the concentrated or membrane filtration of the coagulating sedimentation of employing and gravity to recycle membrane backwashing abroad.But adopt ordinary method that membrane backwashing is recycled, have following shortcoming: one, needs add coagulating agent, have lost the advantage of membrane technique physical filtering mode; The 2nd, organic efficiency is low; The 3rd, have certain recovery risk, particularly conventional index such as iron, manganese and microbiological indicator (giardia lamblia stiles and Cryptosporidium); The 4th, even adopt submerged membrane to filter, used film also is very easy to stop up, pollute, and the life-span is very low; The 5th, cost of investment is high, needs to increase equalizing tank, coagulative precipitation tank or pond for recovering, and the 6th, running cost and energy consumption are high.
Summary of the invention
The objective of the invention is to overcome or improve the shortcoming of prior art, a kind of water-saving surpassing/the micro-filtration water-purifying apparatus is provided, guaranteeing to produce under the prerequisite of water water quality; Both raised the efficiency; Improve the water recovery utilization rate of film system again, reduced discharged waste water, practiced thrift great amount of water resources; Farthest reduce cost of investment and running cost simultaneously, reduce energy consumption.
A kind of water-saving surpassing provided by the invention/micro-filtration water-purifying apparatus mainly comprises:
(1) service pump
(2) ultra/micro-filtrate membrane filtration device;
(3) dense water and backwash water pond for recovering comprise flat membrane component, aerating apparatus, granulated active carbon in the pond
(4) Aeration fan
(5) lift pump
(6) water purifying tank
The water purification process: former water is through the service pump laggard excess of imports/micro-filtrate membrane filtration device that pressurizes, and the water that purifies through ultra/microfiltration membrane gets into water purifying tank;
The condensed water and the backwashing water removal process of ultra/microfiltration membrane: the condensed water and the backwash water of ultra/microfiltration membrane get into dense water and backwash water pond for recovering; In pond for recovering, be provided with flat membrane component; The water purification that after flat sheet membrane is filtered, reclaims utilizes lift pump to be drawn into water purifying tank; Also be provided with aerating apparatus and granulated active carbon in the pond for recovering,, reduce the pollution of flat sheet membrane through the mechanical scrub of air and gac; Aeration fan forms little air bubble with air through aerating apparatus and gets into pond for recovering.
The invention has the beneficial effects as follows: the invention solves conventional surpassing/microfiltration membrane water-purifying apparatus and waste the drawback of condensed water and backwash water; Overcome simultaneously the traditional method recycling ultra/the microfiltration membrane condensed water is low with the backwash water organic efficiency, have certain recovery risk, investment and running cost high, increase new problems such as chemical pollution, advantages such as this retrieving arrangement has investment and running cost is low, operational condition is flexible, organic efficiency is high, effluent quality is good, the automatic control degree is high, the continuous operation of low cost for a long time.Adopt the water saving again simultaneously of this device water purifying; Effluent quality satisfies national water quality standard for drinking water requirement, can directly get into water purifying tank after sterilizing outside defeated water supply network, through this device membrane backwashing is recycled in addition; Greatly improved the water recovery of film system; Reduce discharged waste water, practiced thrift great amount of water resources, had remarkable social benefit, environmental benefit and economic benefit.
