[technical field]
The invention relates to technical field of sewage, specifically a kind of tap water secondary pollution advanced treatment cleaner and method.
[background technology]
Clearly defined following major name in the CJ/T206-2005 of the country water examination standard:
Secondary water-supply: by water-supplying unit will be from the city public water supply and make certainly/water supply of facility, through store, pressurization or after advanced treatment and sterilization, water supply line or pipe special by water-supplying unit provides supply water to the user.
The user is subjected to water spot: the user's with water spot (being water tap) in the water supply coverage.
This shows that water-supplying unit carries out " secondary pollution " things such as chemistry that disposal process produces, physics, biology to the user's that comprises water supply coverage with water spot, bear directly, dispose timely obligation.Finally offer the water spot of using of user in the water supply coverage, water quality should meet the test item stipulated in the above-mentioned standard and the test rating of other projects.
How stoping the infection chain of bacterium from the source, prevent " secondary pollution " of city domestic water, is the focus that domestic and international environmental administration and expert pay close attention to for a long time.All kinds of waters in city, as live and use cold and hot water, the cold heat medium water of central air-conditioning, industrial circulating water, agricultural, the spray of urban afforestation, irrigation water, water pipe network systems such as fire-fighting, after using 1-2, that have even in the shorter time, influenced by envrionment temperature etc., the various mineralizers that exist in the water, through the micro cell reaction, can produce corrosion, algae and bacterium are grown in fouling, cause " secondary pollution " of domestic water pipe network system, cause the interior current of pipe network to diminish, stop up, water clock, the problems such as pipe of exposing to the sun, the especially burst when heat and severe winter allows people's headache really.Townie people nearly all can be such experience: the tap of fetching boiling water early morning, the tap water regular meeting that flows out is being with one iron rust peculiar smell, also can see the suspended substance that trickle yellow or reddish-brown are arranged if examine: the position that bathtub, pond etc. drips for a long time, can both see having yellow rust staining; After pot-type boiler used 1-2, current diminished, and the tap of fetching boiling water is also with yellow rust water, and the spray header place has rust deposite, and energy consumption also increases along with thickening of fouling; Long-term untreated toilet flush inwall covers with sticky thing of one deck (microorganism) and algae substances.
