Description
One, technical field
The present invention relates to a kind of pipeline type defluorination method.
Two, technical background
The water that the long-term drinking fluorine content exceeds standard causes great harm to HUMAN HEALTH, is divided into three major types with regard to drinking water defluorination method approximately, and reverse osmosis, electric osmose wash rice and absorption method are arranged.General all is that the defluoroing water after purifying is flow in the hold-up vessel, pump with pump again and enter that pipe network supplies water or the terminal water user, in fact this is exactly second water supply, increase opportunities for contamination and because of the required floor space of erecting equipment, strengthen facility investment and because of the cost that secondary water-supply brought, to very inconvenience and unfavorable of water user.
Three, summary of the invention
The purpose of this invention is to provide a kind of pipeline type defluorination method, this method is compared maximum difference and is that all defluorination processes all are to carry out in confined conditions with other method, in fact be exactly on pipeline section, to add a fluorine removal device, can reduce problems such as the required floor space of facility investment, pollution, sterilization and erecting equipment that brings because of secondary water-supply is warming like this.Its generation is because the novel material new technology occurs and the progress of water treatment technology, at first be to have the defluorinating agent of high adsorption capacity to accelerate rate of adsorption, the secondary filter of mechanical filter and PP cotton, can hold back and reach the trace impurity that sorbent material produced in the pipeline, ultrafiltration then can be held back macromolecular substance and bacterium and virus, above-mentioned holding back can be carried out under pressure≤0.3Mpa, and can borrow the pressure of pipeline self to discharge outward by bypass.And the defluorinating carbon post can be considered expanding partly of pipeline, and sorbent material can dynamically and under the normal temperature and pressure adsorb fluorine quiet.Therefore, can and be touched duration of contact of thing according to the loading capacity of defluorinating agent, just can calculate tank body water flow velocity, diameter, add defluorinating carbon amount and mode of connection.Adopt that this pipeline type defluorination method is just a bit of from former pipe network an expansible defluorination assembly to have occurred.This defluorination method is undertaken by following process:
1, material and assembly, 1. defluorinating agent, its loading capacity of defluorinating carbon of selecting adsorptive type for use is greater than 5mg/g, pulverize broken 8～60 mesh sieves that caused, 2. column tank body, choose down the band mouth and the alkali-proof glass steel or stainless steel that can be connected with pipe fitting, its tank body height should be not less than 1.5 meters, and diameter is decided as required, and withstand voltage Strong degree is answered 〉=0.6MPa, 3. mechanical filter, select for use different grain size quartz sand to form according to flow velocity, 4. activated carbon column is selected according to the water supply quality needs, gac requires the 10-40 order, 5. accurate filter is used PP cotton filter core, 6. ultrafiltration, select according to the water supply quality needs, use the PP hollow fiber ultrafiltration membrane, 7. under meter is selected model as required for use;
2, tinning is packed quartz sand, defluorinating carbon and gac in the column jar separately, and it highly is about about 2/3rds of column tank body;
3, install, accurate filter and ultrafiltration select different size to assemble according to flow velocity;
4, connect, earlier mechanical filter, defluorinating carbon post, activated carbon column, accurate filter, ultrafiltration and under meter are communicated with in order, these several assemblies can form single channel multiple series series or parallel connection by stopping valve and pipeline are installed, use for independent or serial or parallel connection, the assembly of this connection pattern must be two covers, is equipped with a usefulness for one.And then this two grip assembly is communicated with the mode that the water pipeline props up with bypass or side by stopping valve and pipeline, so just forming original water pipeline can directly not use by the defluorination pipeline, can change the mode that the path of original water changes into by defluorinating carbon assembly external member by stopping valve yet and supply water;
5, the operation of pipeline type defluorination method, must be before using pipeline type defluorination method earlier with mechanical filter, defluorinating carbon and activated carbon column the pipeline exterior-applied liquid medicine repeatedly separately flushing till qualified, inferior back is checking whether connect the appropriate ne-leakage situation that has by the order of connection and mode, carry out the flushing of pipeline again, regulate flow velocity by observing under meter, be adjusted to till qualified water and the desired flow rates, then original ventilating water pipe is changed the water-flowing path formula defluorination path that turns into the line by the mode that changes stopping valve and use, if break down or overhaul and change the standby cover of convertible use.
