Abstract
The present invention relates to a compound sewage flocculant, belonging to the field of water treatment. It is characterized by that it has three agent types, in which agent A and agent B are flocculants, and agent C is a coagulant aid. Said invention has the strong flocculation and coagulation aiding functions, and can make the pollutant in the sewage flocculate and quickly sedimentate. When using, said three agent types must be compounded to use, and according to the pH value of sewage, firstly the agent A and agent B are used to regulate pH value, and then agent C is added to give aid to coagulation. Said invention can be used for treating any industrial waste water and domestic sewage. Its material source is extensive, process is simple and easy to popularize for use.
Description
The invention belongs to water treatment field, relate to a kind of preparation and application of compound sewage flocculating agent, can be widely used in various trade effluents and domestic sewage treating.
Along with development of modern industry, the discharging of a large amount of trade effluents, severe contamination the environment of human survival, water resources is destroyed, original ecological balance is broken, and is human problem demanding prompt solution so solve that water pollutes.
The sewage flocculant that generally adopts in the water treatment at present has Indian red, Tai-Ace S 150, aluminium chlorohydroxide, basic aluminium sulphate, alum and some other inorganic polymer flocculants, though they all have detergent power to sewage, but its flocculation, sedimentary time are all long, and consumption is big, ton water treatment expense height, be difficult to form large-scale throughput, the factory that has at present uses bauxite instead and produces polymerize aluminum chloride (PAC), but its complex process, production cycle is long, corrodibility to equipment is also big, the product cost height, and the user is difficult to accept.
The objective of the invention is to propose a kind of not only cheap, but also compound sewage flocculating agent easy to use, can adsorb rapidly, impurity and pollutent in the sewage that flocculates, form big throw out and sink fast, sewage is purified.
Technical scheme of the present invention is: this compound sewage flocculating agent comprises A agent, B agent and C agent, and the A agent is that the copperas solution by the alum liquor of 20% concentration and 20% concentration mixes, and wherein alum liquor accounts for 70-80%, and copperas solution accounts for 20-30%; The B agent is to be that 20% calcium oxide solution and concentration are that 0.01% potassium permanganate solution mixes by concentration, and wherein calcium oxide solution accounts for 80-90%, and potassium permanganate solution accounts for 10-20%; The C agent is the polyacrylamide solution of 0.02% concentration.Aforementioned proportion is weight ratio.
The A agent of compound sewage flocculating agent and B agent are flocculation agent, and the C agent is a coagulant aids, during use, according to the potential of hydrogen of sewage, add the pH value that sewage is regulated in A agent and B agent earlier, add the C agent again and help with fixed attention.When handling sour water, with the B agent pH value of sewage is transferred to 8-10 earlier, with the A agent pH value of sewage is transferred to 6-7 again, add the C agent at last and help with fixed attention; When handling alkaline sewage, then with the A agent pH value of sewage is transferred to 3-5 earlier, with the B agent pH value of sewage is transferred to 6-7 again, add the C agent at last and help with fixed attention; When handling neutral sewage, method is with handling alkaline sewage, and the pH value of adjusting sewage with the A agent transfers to 6-7 with the B agent again to 3-5 earlier, adds the C agent at last and helps with fixed attention, gets final product in static 20-30 minute.
Compound sewage flocculating agent of the present invention has very strong flocculation and helps the effect of coagulating, can make the colloidal particle loss of stability in the sewage, increase the opposite charges between the suspended particles, attract each other, form big floc sedimentation and sink fast, the clearance of the COD in the sewage, BOD, SS colourity all reaches about 90%, and water quality is transparent, can not only make sewage reach discharging standards, can also return in the industrial and agricultural production water.This flocculation agent is not subjected to the restriction of sewage potential of hydrogen, can regulate the pH value of sewage arbitrarily, and this is that general flocculation agent is incomparable, adopts this invention to handle any trade effluent and city domestic sewage, than fast 10 times with other method speed.Starting material wide material sources of the present invention, cheap, preparation technology is simple, and is good in economic efficiency, is easy to apply.
Realize that specific examples of the present invention is:
At first produce A agent, B agent, C agent.
Get Tai-Ace S 150 150 grams, after the pulverizing, put into dissolving vessel, add 750 ml waters, start agitator, make it fully be dissolved into the solution of 20% concentration; Get ferrous sulfate 50 gram again, after the pulverizing, put into dissolving vessel, fully stir, making it fully be dissolved into concentration is 20% solution, then alum liquor and copperas solution is added in the chemical combination jar, starts agitator, makes two kinds of solution thorough mixing promptly make the A agent.
Get calcium oxide 100 gram, add in the dissolving vessel, add 500 milliliters in water, start agitator, fully be dissolved into milk of lime, filter, make concentration and be 20% calcium oxide solution through 40 mesh sieves through pulverizing; Get potassium permanganate 0.01 gram again, add 100 milliliters water, be dissolved into concentration and be 0.01% potassium permanganate solution, then two kinds of solution thorough mixing are promptly made the B agent.
Get polyacrylamide 2 grams, add 1000 milliliters in water, put into dissolving vessel,, make the C agent through fully stirring, dissolving.
A agent and B agent are flocculation agent, and the C agent is a coagulant aids, during use, need the potential of hydrogen according to sewage, regulate the pH value of sewage earlier with A agent and B agent, add the C agent again and help with fixed attention.
Handle (is example with ton water) according to different sewage:
Handle the method for sour water:
The B agent that at first will prepare adds in the sewage, and evenly stirs, and the limit adds B agent limit and stirs, when the pH value of sewage reaches 9, stop to add the B agent and stop to stir, after static 2 minutes, begin to add the A agent that has prepared and begin even stirring simultaneously, when the pH value of sewage reaches 6, stop to add the A agent and stop stirring, static 2 minutes, add the C agent and the stirring simultaneously that have prepared at last, stop after three minutes stirring, static, precipitation 30 minutes promptly obtains standardized water purification.The consumption of A agent and B agent is decided with pH value, and the consumption of C agent is 250 milliliters.
Handle the method for alkaline sewage:
The A agent that at first will prepare adds in the sewage, and evenly stirs, and the limit adds A agent limit and stirs, when the pH value of sewage reaches 4, stop to add the A agent and stop to stir, after static 2 minutes, add the B agent prepared, and begin even stirring simultaneously, when the pH value of sewage reaches 7, stop to add the B agent, stop simultaneously stirring static 2 minutes, add the C agent that has prepared at last, stirred 3 minutes, through static, the precipitation 30 minutes, the water purification after promptly obtaining handling.The consumption of A agent and B agent is decided with the pH value of sewage, and the consumption of C agent is 250 milliliters.
Handle the method for neutral sewage:
The A agent that at first will prepare adds in the sewage, and evenly stirs, and adds the A agent and stops immediately stirring, and the B agent that will prepare again adds in the sewage, and stirs, and add the B agent and stirred 3 minutes, static 2 minutes, add the C agent at last, quiescent setting got final product in 30 minutes.Its consumption A agent is 2000 milliliters, and the B agent is 1000 milliliters, and the C agent is 250 milliliters.
It is standard up to standard that the supernatant liquor of post precipitation filters through the charcoal ash again, recyclable utilization or discharging, and lower floor's mud can fully utilize.
Enclose compound sewage flocculating agent below and handle the water sample monitoring of trade effluent
