Description
Technical field
The present invention relates to environment, cardiovascular drugs, water resources to recycle field, specifically a kind of to utilize Chemical Regulation side
Method reduces concentration of nitrogen and phosphorus and the synchronous method for realizing cardiovascular drugs removal in Heisui River.
Background technique
Nowadays, there are a large amount of micropollutants in environmental wastewater.Meanwhile because natively existing in Heisui River largely may be used
Cause the phosphorus and nitrogen of environment water eutrophication, these can all increase the difficulty that usage on black water and water resource recycle
Degree.
Currently, in Heisui River the minimizing technology of phosphorus and nitrogen and technical level specifically include that microwave high-level oxidation technology,
Bioelectrochemistry processing method, membrane processing method and reverse osmosis etc..Although these methods can reduce in waste water to varying degrees
The concentration of nitrogen phosphorus increases a possibility that Sewage treatment utilizes, but it is reducing micropollutants concentration level, improves water reuse
It is all not fully up to expectations in terms of environmental-friendly degree.
Because current cardiovascular disease is high-incidence, detectable concentration of the therapeutic agent in Heisui River also cumulative year after year.For example,
A kind of hypertension, the concentration of anginal Common drugs metoprolol in the environment are just changed to from the μ g/L order of magnitude in 19th century
The mg/L of 21 century.The variation of this concentration increases the difficulty of wastewater treatment, it is necessary to draw attention.
Summary of the invention
The problem of present invention aim to address the processing of the environmental-friendly and efficient stable in the Heisui River containing beta blocker, provides
A method of beta blocker content in Heisui River is reduced simultaneously using the nitrogen phosphorus in pH regulating device processing Heisui River.
Because recovery of nitrogen and phosphorus process lasts slowly, main nucleation settlement stability process is completed in preceding 120min, together
When recovering effect superiority and inferiority and the absorption of micropollutants influenced by pH than more significant, therefore in actual removal process,
PH must be made to reach stable, accurate ideal value in a short time, just can guarantee that the recycling in Heisui River will not be to ecology in this way
Environment causes damages.
The technical scheme is that
A method of recovery of nitrogen and phosphorus and synchronous absorption beta blocker, specific steps in Heisui River are realized using pH regulating device
It is as follows:
Step 1), Heisui River water sample are pumped into, and extracting appropriate Heisui River water sample to be processed makes by simple filtration treatment
After water sample is without apparent suspended impurity, it is pumped into equipment container through conduit；
Heated at constant temperature instrument is opened in step 2), constant temperature processing, so that water sample is always maintained at 30 DEG C in whole reaction process, warp
Certain heating and thermal insulation processing is crossed, the treatment effect of water sample will be guaranteed；
Step 3), the NaOH solution and HCL that a certain amount of 1mol/L will be separately added into two containers of pH regulating device
Solution opens pH and adjusts display device, sets suitable pH target value；
Step 4), pH regulatory function are started to work, and entire treatment process is stablized in pH=10.5, working time 3h.
Further, Heisui River water sample described in step 1) is to include Mg2+:NH4 +:PO4 3-The Hei Shuishui of=1.8:1:1
Sample.The beta blocker is metoprolol, times Ta Luoluoer, Propranolol standard items.
Further, Heisui River water sample described in step 1) is filtered by 0.22 μm of cellulose acetate sheets.Step 3)
Middle NaOH solution and HCL solution additional amount are 1L.
Further, the removal rate of nitrogen phosphorus is 94.8%-96% in the Heisui River.The beta blocker removal rate is
45%-50%.
The invention has the advantages that
Without complicated condition, it was not only able to achieve the recycling of nitrogen phosphorus in Heisui River, but also the concentration of beta blocker in Heisui River can be reduced,
The eco-environmental impact in Heisui River after reduction processing.By processing, nitrogen phosphorus is generated in the form of guanite, and the rate of recovery reaches
95.5% or more.The removal rate of beta blocker reaches 45%, and the common removal that this is significantly higher than Beta receptor blockers is horizontal.By processing
Heisui River afterwards, the requirement for being able to satisfy black water discharge and recycling.
Detailed description of the invention
Fig. 1 is recovery of nitrogen and phosphorus and to adsorb the apparatus structure schematic diagram of beta blocker in the Heisui River with pH regulating device.
In figure, 1-pH meter, 2-NaOH NaOH solution tank NaOH, 3-HCL NaOH solution tank NaOH, 4- pump, the filtered Heisui River sample of 5-, 6- heating
