3after river pumps into, drop into 150ppm bacterial classification (4 × 10
5~ 4 × 10
6cfu/L, the genus bacillus consisting of equal proportion of bacterial classification, actinomycetes and pseudomonas), continuous aeration 3d, start ceramic membrane solid-liquid separation system afterwards, ceramic membrane goes out water management at 8.3m
3/ h, makes the reaction tank residence time be 2h, and reaction tank water inlet adopts water lev el control, when reaction tank water level reduces, automatically start intake pump, directly pump into river, system runs 30 days continuously, to complete bio-film colonization (obtaining biological activated carbon particle), obtains the water purification system of steady running.
Result shows, between the limber up period of 30 days, the removal rate of reactive system to COD and ammonia nitrogen shows as identical rule, is all first high, in reduction, slowly rises to stable subsequently.Run first 5 days, COD removal rate is 40%-50%, and within 6-9 days subsequently, be reduced to about 20%, progressively rise afterwards, to 22 days, system was stablized to 50-60% COD removal rate.Run first 6 days, system ammonia nitrogen removal rate is 20%-30%, and within 7-13 days subsequently, be reduced to about 10-20%, progressively rise afterwards, to 15 days, system was stablized to about 30% ammonia nitrogen removal rate.This shows, the starting stage for the treatment of process, to the removal of COD and ammonia nitrogen to be adsorbed as master, along with carrier adsorption is saturated, more and more lower to contaminant removal rate; In the later stage, carrier starts biofilm, therefore COD and ammonia nitrogen removal rate are being reduced to a certain degree, start to rise, finally be stabilized in certain numerical value, because Activated Carbon for Adsorption of Organic effect is much larger than to ammonia nitrogen system, the inventive method is greater than the removing to ammonia nitrogen to COD removal rate.
different methods decontamination effect improving compares:
Use the Water warfare of steady running of the present invention, sand filtration, the former water of activated carbon filtration respectively, detect its decontamination effect improving afterwards.Concrete filtration, purification process is as follows:
The operating parameter of the water purification system of steady running of the present invention is: concentration of medium 3%, residence time 2h;
Sand filtration operating parameter is: 2-3mm sand grains, filtering velocity 10m/h;
Activated carbon filtration is 5mm granulated active carbon, filtering velocity 10m/h,
Above-mentioned 3 kinds of process run 5d all continuously, compare it afterwards to former water purification effect.Experimental result is as follows:
Result shows.No matter be to the conventional index such as COD, ammonia nitrogen, or UV254, photogenic bacterium relatively press down light rate, the inventive method removal rate is all higher than sand filtration and activated carbon filtration.The inventive method is respectively 58.6% and 15.5% to COD and ammonia nitrogen removal rate, and activated carbon filtration is respectively 24.6% and 12.5% to COD and ammonia nitrogen removal rate, and sand filtration removal rate is extremely low; The inventive method is to UV254 with relative to press down light rate effect better, and decline 76.3% and 46.9% respectively, activated carbon filtration also has certain effect to the former water toxicity of reduction, UV254 and relative but light rate declines respectively 39.8% and 22.0%1.And sand filtration there is no effect to river removing toxic substances.
the water purification system parameter testing operation method of steady running of the present invention:
By changing the water yield in reaction tank, making system media (biological activity carbon powder) concentration (mass percent) be in 1%, 3%, 5% level respectively, under the operational conditions of the 2h residence time, comparing Inlet and outlet water water-quality guideline.Experimental result is as follows:
Result shows, carrier concn has certain influence to detoxifying effect, when carrier concn rises to 3% by 1%, UV254 and the relative light rate down ratio that presses down are respectively by 60.3%, 30.5% rises to 80.2% and 49.0%, continue afterwards to improve carrier concn, little on detoxifying effect impact, UV254 only has faint rising with the relative light rate down ratio that presses down, when carrier concn rises to 5%, UV254 only rises to 83.1% and 51.7% with the relative light rate down ratio that presses down, consider running cost and ceramic membrane solid-liquid separation system separation efficiency, reaction tank carried by active carbon bulk concentration is advisable with about 3%.
Extract the former water of cultivation of another batch, when concentration of medium is 3%, by adjustment ceramic membrane water flow, make the system residence time be respectively 1h, 2h, 3h, 4h, 5h, test macro is to river water cleaning effect.Experimental result is as follows:
Result shows, there is certain influence the residence time to detoxifying effect, when the residence time rises to 2h by 1h, UV254 and the relative light rate down ratio that presses down are respectively by 66.4%, 35.6% rises to 76.3% and 45.6%, continue afterwards to improve the residence time, little on detoxifying effect impact, along with the residence time rises to 3h, 4h, 5h, UV254 only has faint rising with the relative light rate down ratio that presses down, rise to 80.5% and 51.2% respectively, 81.8% and 49.7% and 80.5% and 53.3%, consider running cost and reactor floor space, the reaction tank residence time is advisable with about 2h, the increase residence time can not significantly increase system detoxifying effect.
