Abstract
Disclosed is an amorphous flocculus water contaminant static adsorption capacity testing device which is used to test the capability of amorphous flocculi produced by various flocculated medicaments for absorbing various water contaminants under static state. The essential member of the testing device is an up-flow adsorption column. A bearing layer is arranged at the bottom of the adsorption column and a flocculus to be tested is statically arranged on the bearing layer. The testing device is provided with a wiggly metering pump which transports contaminant solution to the absorption column quantitively. The contaminant solution runs through a flocculus layer of the absorption column from bottom to top; part of the contaminants is absorbed by flocculus layer; and the remaining contaminants enter the overlying water inside the absorption column. Meanwhile, the absorption column is provided with an aeration system which can thoroughly mix the liquid inside the absorption column and drain the overlying water overtopping the control liquid level inside the absorption column under the action of air pressure. By testing the contaminant content change of the overlying water drained from the absorption column, the testing device can calculate the real-time contaminant adsorption amount of the flocculus layer and thereby characterizes the adsorption capacity of the flocculus to various contaminants.
Description
Affiliated technical field
The utility model relates to a kind of proving installation of flco absorption property, is used to study the Static Adsorption ability of amorphous flco to water pollutant.
Background technology
The research environment-friendly materials adopt isothermal adsorption experiment under the oscillating condition usually to the absorption property of pollutant.In the pollutant solution of a series of variable concentrations, add a certain amount of sorbing material, under the uniform temperature condition, vibrate a period of time,, can calculate the adsorbance of sorbing material under the different condition by measuring pollutant levels in the solution of vibration front and back.But fragmentation can take place in amorphous flco under oscillating condition, therefore can't adopt the isothermal adsorption test under the oscillating condition to study its absorption property.For the situation of flocculating agent coagulant precipitation removal water pollutant, still can use the coagulation test stirring instrument of standard to study.But in the part field of engineering technology, the mechanism of action of amorphous flco is not coagulant precipitation.As the polluted bed mud in-situ passivation technology in the lake endogenous pollution improvement, this technology is the flco that has very strong adsorptive power at polluted bed mud surface coverage one deck, and flco adsorbs the pollutant that discharges in the bed mud under static condition.In the case, Chang Gui coagulation test method is inapplicable equally.
Summary of the invention
Can't be applicable to the Static Adsorption ability of the amorphous flco of research fully at the existing conventional experimental technique to water pollutant, the utility model proposes a kind of experimental apparatus for testing, this device can be studied the adsorptive power of amorphous flco to water pollutant under static condition.
Main member of the present utility model is a up flow type adsorption column, amorphous flco static state places on the adsorption column supporting layer, in adsorption column, carry certain density pollutant solution quantitatively by peristaltic pump, measure adsorption column effluent pollutant levels, can calculate the amount of amorphous flco absorb polluted matter according to material balance principle.The up flow type adsorption column is the two ends rubber stopper seal up and down, and the bottom rubber plug has water inlet pipe mouth, and the top rubber plug has aeration tube import and two openings of exhaust water delivering orifice.Water inlet pipe mouth connects peristaltic pump, by the quantitative conveying pollutant solution in adsorption column of peristaltic pump.Pollutant solution can successively slowly pass through amorphous flco adsorbed layer by sponge water distribution layer and quartzy core supporting layer after entering adsorption column then.In process by amorphous flco adsorbed layer, the part pollutant is adsorbed, passing the amount that adsorbed layer enters the pollutant of overlying water has like this lacked much than the operational throughput of peristaltic pump in adsorption column, by real-time monitoring to pollutant levels in overlying water and the effluent, calculate according to material balance principle, just can draw the absorption situation of the amorphous flco layer of day part pollutant.The effect of the layer of sponge water distribution here is to make from the pollutant solution of water inlet pipe inflow evenly to join cloth on the whole section of adsorption column, and the effect of quartzy core supporting layer is to support amorphous flco, and certain water distribution effect is also arranged simultaneously.In experimentation, continue aeration by air boost pump overlying water in adsorption column.The effect of aeration has 2 points: by aeration the adsorption column overlying water is fully mixed on the one hand, avoid overlying water appearance concentration gradient from bottom to up; Keep liquid level in the adsorption column by aeration on the other hand, adsorption column is sealed at both ends up and down, the air that enters in the adsorption column can only be discharged by the exhaust water delivering orifice on top, along with pollutant solution is constantly imported adsorption column, when liquid level in the adsorption column rises to the exhaust water delivering orifice, the gaseous tension that aeration forms will promote part solution and flow out adsorption column by the exhaust water delivering orifice, and till the exhaust effluent pipe mouth was exposed in liquid level decline, liquid level remained on exhaust effluent pipe mouth place in the adsorption column thereby make.Exhaust water delivering orifice effluent is collected in the scale test tube, monitors in real time.
The beneficial effects of the utility model are, can study the real-time absorption situation of amorphous flco to water pollutant under static condition, characterize the adsorptive power of amorphous flco.
