Abstract
A deeper treating process for drinking water features use of complex filter material in dechlorinating filter for dechlorination, new-type elastic filler in filter pool of new-type biologic tower for natural aeration, and use of biologic oxidation, ultraviolet catalytic oxidation and biologic oxidation to remove the harmful microbes, toxic matter, odour and colour while retain useful elements to human body.
Description
The present invention relates to water treatment, belong to drink water purifying process for producing method especially.
Water is the source of all things on earth, and along with development of modern industry, the water source is polluted gradually to be destroyed, and noxious pollutant content rises year by year in the tap water, and kind increases year by year, brings harm for human lives and health.The conventional water treatment process of waterworks can not be removed solvability objectionable impurities in the water fully.For improving the tap water quality of water supply, satisfy the high water quality requirement of office, school, army, enterprises and institutions, residential building, whole world scientific and technical personnel have carried out a large amount of development work.Propose various water conditioning methods, made multiple water treatment equipment, produced pure water, water purification, artificial mineral water, distilled water or the like.For example publishing ozone one biological active carbon purifying technical process on Shanghai environmental science publication the 9th the 1st phase of volume of nineteen ninety, realizing water quality advanced processing, water-supply plant or water-supplying unit of collective use.But this treatment process lacks aeration and bio-oxidation, handles and ultraviolet catalytic oxidation except that giving of ammonia nitrogen, has influenced removal effect of organic matter, and treatment unit costs an arm and a leg simultaneously, and current consumption is big.
The purpose of this invention is to provide a kind of process for deeper purifying drinking water, it can be removed effectively and be harmful to the various inorganic of human body in the tap water, and organic pollutant, pathogenic micro-organism keep the inorganic elements that is of value to HUMAN HEALTH in the water, improve the mouthfeel of water.
The present invention realizes by following processing step, with tap water by coarse filtration, dechlorination, aeration aerating and bio-oxidation, filling oxygenant, ultraviolet catalytic oxidation, biological activated carbon bio-oxidation once more filter, smart filter, disinfect the back and become water purification.
The drinking water deep processing technological flow that the present invention adopts, make that harmful poisonous inorganics, organism, pathogenic microorganism, undesired off taste material and colourity etc. are purified and remove in the water, keep the inorganic elements that is of value to HUMAN HEALTH in the water, make the positive water of Ames mutagenicity test change into negative water, water quality is better than national drinking water standard, also has the low advantage of a whole set of treatment unit cost simultaneously.
Fig. 1 is a process flow sheet of the present invention.
The invention will be further described below with reference to embodiment shown in the drawings.
As shown in the figure, the technical process in purified water treatment device: adopt the tap water or the surface water to make the water source, water is fed carry out coarse filtration 1 in the strainer, wire-wound filter element filtering, purification are arranged in the strainer; Dechlorination 2 is to finish by the dechlorination filter, and KDF and medical stone composite filtering material are housed in the dechlorination filter, and it can be removed and remain chlorine in the water, and can not cause zine ion to exceed standard; Aeration aerating and bio-oxidation 3 are to carry out in new bio tower filter tank, adopt the novel elastic filler in the tower, it can be YDT, also can be the annular resilient filler, can make into water natural aeration, blows away the organic objectionable impurities of lower boiling in the water, increase oxygen in water, the microbial film of growing on the filler can make in the water albumen ammonia transform the ammonification rear oxidation and become nitrite and nitrate, removes stink in the water simultaneously, organism in the water of decomposition is for subsequent disposal creates conditions; The oxygenant charging point oxygenant 4 that is used for annotating, it can be hydrogen peroxide (H
2O
2), ozone (O also can annotate
3); Ultraviolet catalytic oxidation 5 is to be finished by the ultra violet lamp of being adorned in the photochemical catalytic oxidation device, makes the oxygenant of adding be transformed into the stronger free an aromatic plant metioned in ancient books (OH) of oxidizing power and is used for organism in oxidation, the water of decomposition, removes carcinogenic and mutagenic matter in the water; Biological activated carbon bio-oxidation filtration 6 once more is to finish by biological activated carbon filter, and length is housed in the pond biomembranous granulated active carbon, and poisonous and hazardous organism, inorganics and ammonia, nitrogen are further removed; Smart filter 7 is carried out in secondary filter, and filter membrane is housed in the secondary filter, and it can use the spirally wound film, also can use tubular fibre, is used for holding back bacterium, reduces turbidity; Sterilization 8 usefulness dioxide peroxide or hydrogen peroxide are finished, and to prevent bacteriological aftergrowth, drink water purifying are guaranteed.Present embodiment detects online extra large measuring station through legal detection unit one Chinese cities and towns water supply quality and detects, and the partial results that this technology is purified waste water is as follows:
| Project | National standard | Water inlet | Water outlet |
| The colourity degree | Less than 15 | ????8 | Less than 5 |
| Turbidity NTU | Less than 3 | ????1.2 | Less than 0.15 |
| The total organic carbon mg/litre | ????4.9 | Less than 1.3 | |
| The chloroform mg/litre | Less than 0.06 | ??0.0093 | Less than 0.0019 |
| The tetracol phenixin mg/litre | Less than 0.003 | ??0.00031 | Less than 0.00003 |
| The Ames mutagenicity test | Positive | Negative |
Claims (3)
1 one kinds of inferior water process for deeper purifying is characterized in that tap water is passed through coarse filtration, dechlorination, aeration aerating and bio-oxidation, and filling oxygenant, ultraviolet catalytic oxidation, biological activated carbon bio-oxidation once more filter, and essence becomes water purification after filtering, disinfecting.
2 advanced water treatment treatment process according to claim 1 is characterized in that dechlorination is to come dechlorination with the composite filtering material of being made up of KDF and medical stone that is provided with in the dechlorination filter.
