Background technology:
The production method of existing tap water is generally obtain source water from river, then successively through flocculation, precipitation, sand filtration, add sterilizing agent sterilization after just become tap water, this kind of production method is just effective when Yuan Shui reaches the standard of three class water, when source water does not reach the standard of three class water, can only stop producing.Now, along with industrialized progress, the pollution condition in river is more and more serious, the situation that source water does not reach the standard of three class water frequently occurs, seriously have impact on the regular supply of tap water, in order to avoid the life affecting people as far as possible, when not up to standard because of slight pollution, tap water manufacturing enterprise often just produces tap water unceasingly, damages the health of user like this with regard to easily causing can't meet the quality requirement of tap water.
Summary of the invention:
Even if goal of the invention of the present invention is to provide a kind of source water also can carry out tap water production under slight pollution, and can ensure that the quality of water reaches requirement, and the production method of the tap water of tap water production system can be entered by the serious source water of preventing pollution.
The present invention realizes like this, comprise source water quality testing and analysis system, source water is the tap water production system of more than three class water, in the water of source, only ammonia nitrogen slightly surpasses the tap water production system of the standard of three class water, in the water of source, only micro-Organic Pollutants slightly surpasses the tap water production system of the standard of three class water, in the water of source, only heavy metal or mixed pollutants slightly surpass the tap water production system of the standard of three class water, source water quality testing and analysis system comprises water quality detection, water quality judges, water quality detection is by manually detecting source water incessantly or detected source water continuously by automatic detection device according to national standard, then detected result is sent in real time water quality to judge, water quality judges then to compare with national standard according to detected result, judge that source water is that it is that to belong in five kinds, five kinds are respectively: A, source water is more than three class water, in B, source water, only ammonia nitrogen slightly surpasses the standard of three class water, in C, source water, only micro-Organic Pollutants slightly surpasses the standard of three class water, in D, source water, only heavy metal or mixed pollutants slightly surpass the standard of three class water, E, except A, B, C, source water outside D is attached most importance to polluted water, if source water is category-A water, it is then the tap water production system of more than three class water by Shui Daoqu source, source water, if source water is category-B water, then by the water of Shui Daoqu source, source only ammonia nitrogen slightly surpass the tap water production system of the standard of three class water, if source water is C class water, then by the water of Shui Daoqu source, source only micro-Organic Pollutants slightly surpass the tap water production system of the standard of three class water, if source water is D class water, then by the water of Shui Daoqu source, source, only heavy metal or mixed pollutants slightly surpass the tap water production system of the standard of three class water, if source water is E class water, then block source water supply and send alarm signal, the tap water production system that in the water of source, only ammonia nitrogen slightly surpasses the standard of three class water comprises successively and adopts ammonia nitrogen class flocculation agent and suspended particulate class flocculation agent to carry out the flocculation process flocculated, precipitation process, ammonia-nitrogen desorption biological active filling material preoxidation Micropollutants process, sand filtration process, add sterilizing agent process, the tap water production system that in the water of source, only micro-Organic Pollutants slightly surpasses the standard of three class water comprises successively and adopts ammonia nitrogen class flocculation agent and other organic pollutant class flocculation agent and suspended particulate class flocculation agent to carry out the flocculation process flocculated, precipitation process, charcoal absorption ozone oxidation and light urge matchmaker's treating processes, sand filtration process, add sterilizing agent process, the tap water production system that in the water of source, only heavy metal or mixed pollutants slightly surpass the standard of three class water comprises successively and adopts ammonia nitrogen class flocculation agent and other organic pollutant class flocculation agent and heavy metal class flocculation agent and suspended particulate class flocculation agent flocculation process, precipitation process, ammonia-nitrogen desorption biological active filling material preoxidation Micropollutants process, bioactive percolated wall treating processes, gac ozone oxidation and light urge matchmaker's treating processes, sand filtration process, add sterilizing agent process.
The present invention is categorized into four classes owing to have employed Jiang Yuanshui, then the quality index according to four class water adopts corresponding water technology to remove source pollutant in water, ensure that produced tap water meets standard for drinking, and, need not when source water slight pollution, stop the production of tap water, thus ensure that the regular supply of tap water as much as possible, to meet the needs of people's daily life.
Here, in the water of source, only micro-Organic Pollutants slightly surpasses in the tap water production system of the standard of three class water, enters before employing ammonia nitrogen class flocculation agent and other organic pollutant class flocculation agent and suspended particulate class flocculation agent carry out the flocculation process flocculated first process through oil removal process at Yuan Shui.Because only micro-Organic Pollutants slightly surpasses in the source water of the standard of three class water, often all contain a small amount of greasy dirt, process through oil removal process, can wipe oil effectively, a greasy dirt affects normally carrying out of the process of follow-up water.
Bioactive percolated wall process is made up of activated filter film wall filtration procedure, active diafiltration wall treating processes successively; activated filter film wall filtration procedure be utilize form bacteria cell wall the saccharan of cell surface, phosphoryl, hydroxyl, chloro, comprise food nitrogen, oxygen, phosphorus, the ligating atom of sulphur and metallic ion coordination complexing to realize filtering heavy metal ion in amide group sulfuric acid ester base
Active diafiltration wall treating processes is the various heavy generation biochemical reaction utilizing iron powder and phosphoric acid salt and comprise Ni, Cr, U, Co, Cu,
They are fixed up or are degraded to the material of toxicological harmless.
Compared with the prior art the present invention, even if having source water also to carry out tap water production under slight pollution, and can ensure that the quality of water reaches requirement, and can enter the advantage of tap water production system by the serious source water of preventing pollution.
