Description
Technical Field
The invention belongs to the field of waste liquid treatment, and particularly relates to a cleaning medium waste liquid treating agent and a using method thereof.
Background
In the process of producing a transfer film belt with a zinc sulfide holographic pattern locally in the packaging industry, a water washing method is used for carrying out local windowing treatment on a medium, and in order to ensure the product quality, a large amount of tap water is used for washing, so that a large amount of cleaning medium waste liquid containing zinc sulfide and washing ink is generated, and pollution is caused.
At present, the treatment methods of the waste liquid mainly comprise two methods, one method is to adopt a filtering mode to filter out suspended particles in the waste liquid; and the other is discharged after large-batch dilution. The first method has high cost and low speed, and requires filtering equipment with great vacuum pumping capacity, thus having poor operability; the second method is not environmentally friendly and has been banned by the relevant authorities. Therefore, the urgent need in the industry is to develop a new method for treating the waste liquid of the packaging film cleaning medium.
Disclosure of Invention
The invention aims to provide a cleaning medium waste liquid treating agent and a using method thereof, wherein the treating agent is a multi-component co-group treating agent, and only one treating agent is needed to separate and settle organic resin and inorganic matters in the packaging film cleaning medium waste liquid so as to treat the waste liquid simply and quickly.
The invention is realized by the following technical scheme:
namely, the cleaning medium waste liquid treating agent is characterized by comprising the following raw materials in percentage by mass:
the sodium dodecyl benzene sulfonate is an anionic surfactant and has the functions of controlling the grain size of precipitates and preventing the precipitates from agglomerating.
The powdery ionic polyacrylamide provided by the invention has long chains and is used for flocculating colloid with negative charges.
The dimethyl diallyl ammonium chloride has strong temperature resistance and salt resistance, and the influence of strong electrolyte ions in liquid on a treatment system is relieved.
The benzyl triethyl ammonium chloride is a quaternary ammonium salt phase transfer catalyst and is used for matching with a surfactant to accelerate the system activity.
The calcium lactate of the invention is a stabilizer after emulsion breaking,
the sodium chloride of the invention is strong electrolyte and acts as a demulsifier,
the hexadecyl trimethyl ammonium chloride is a cationic surfactant and acts as a solution stabilizer.
The alkylphenol polyoxyethylene ether is a nonionic surfactant and acts as an emulsifier to promote the dissolution of the components in water.
The ammonium nonylphenol polyoxyethylene ether sulfate is used as a co-emulsifier, and is used together with the emulsifier NP-5 to promote the emulsification effect.
The emulsifier NP-5 of the present invention is a solubilizing wetting agent and an emulsifier.
The saponin of the invention is a deoiling agent.
The silicone oil of the invention is a defoaming agent.
The water of the invention is a system solvent.
The preparation sequence of the treating agent is that the raw materials are weighed according to the weight percentage, water is heated to 40-45 ℃, calcium lactate, sodium chloride, emulsifier NP-5, saponin and silicon oil are added into hot water, and the solution is stirred when the dissolution speed of the saponin and the calcium lactate is slow. Stirring to clear state, adding the rest materials, stirring, cooling, and standing at room temperature in dark.
The cleaning medium waste liquid of the invention has uniform material composition, comprises zinc sulfide, hydrophilic acrylic resin and a small amount of calcium carbonate, and only has slightly different material concentration in the discharge process, in order to treat the cleaning medium waste liquid by adopting a one-step method, the invention creatively improves the proportion of the emulsifier in the formula, and the proportion of the emulsifier is 5-10%, which is greatly different from other treatment systems. According to the invention, while the proportion of the emulsifier is increased, a plurality of emulsifiers are added, the situation of multi-emulsion system cooperative treatment is formed, and the waste liquid of the cleaning medium can be treated by using a one-step method. The treating agent is used for treating the waste cleaning medium liquid, no additional water is needed to be added as a diluent and a viscosity reducer after flocculation is finished, the treatment process is very quick, and the treatment efficiency can be effectively improved.
In the process design of the traditional treating agent, 1) the cationic emulsifier can only act together with the cationic or nonionic emulsifier, and the addition of the nonionic emulsifier can not enhance the emulsifying effect; 2) the cationic emulsifier and the anionic emulsifier or the double-effect emulsifier with anionic property can not act. The two recognition points are the main reason for the fact that co-emulsification in conventional treatment agents is not common. Meanwhile, most of the traditional treating agents are AB agents, and the solvent system is a meta-acid or a meta-alkali, so that the emulsifier can conveniently play a role in the solvent system.
The solvent system of the invention is adjusted to be neutral, and the key point is the ammonium nonylphenol polyoxyethylene ether sulfate which is a co-emulsifier. The ammonium nonylphenol polyoxyethylene ether sulfate is a nonionic and anionic double-effect emulsifier, and forms a strong co-emulsification system with hexadecyl trimethyl ammonium chloride (cationic emulsifier) under the solubilization effect of an emulsifier NP-15 through the combined action of the ammonium nonylphenol polyoxyethylene ether sulfate and alkylphenol polyoxyethylene ether (nonionic emulsifier) in the system. The combined emulsified cleaning medium waste liquid has excellent effect, not only overcomes the conventional method of adopting an AB agent in the prior art, but also has the emulsion effect that the aggregation after emulsion breaking does not need to additionally add a large amount of diluents to reduce the aggregation speed, thereby facilitating solid-liquid separation.
The use method of the cleaning medium waste liquid treating agent is characterized by comprising the following steps:
1) taking 100 parts of cleaning medium waste liquid, uniformly stirring and placing for later use;
2) taking 5 parts of treating agent, slowly stirring the cleaning medium waste liquid at the stirring speed of 100-;
3) and (3) carrying out rapid solid-liquid separation by using a plate-and-frame filter press or a reduced pressure suction filtration device.
The invention aims to increase the reaction uniformity of the treating agent and prevent the insufficient and uneven reaction in the steps 2) of slowly stirring the cleaning medium waste liquid and slowly dripping the treating agent. The stirring speed is 100-120 r/min, the treating agent is at the dropping speed of 60-80 drops/min, and the weight of each drop is 2.0-2.5g, which is a preferable scheme for taking the efficiency and the treatment effect into consideration.
The treating agent prepared by the invention adopts a one-step method to treat the cleaning medium waste liquid, and has the advantages of low cost, low energy consumption, good waste liquid treatment effect and high waste liquid treatment efficiency.
