Abstract
The invention relates to a composite cleaning agent for cleaning a membrane system with organic fouling. The composite cleaning agent is prepared from the following components in percentage by mass: 15 percent of sodium carbonate, 25 percent of EDTA-4Na, 15 percent of sodium citrate, 1 percent of sodium dodecyl benzene sulfonate and 44 percent of pure water and the sodium carbonate, the EDTA-4Na, the sodium citrate, the sodium dodecyl benzene sulfonate and the pure water are subjected to chemical mixing at the normal temperature to form solution. The composite cleaning agent has the advantages that: through multiple effects, the composite cleaning agent removes the pollution of organic matter to the membrane system, can achieve good decontaminating effect, can solve the problem of harm of various pollutants such as inorganic salt, metallic oxide and the like to the membrane system, has wide medicinal effect, can replace multiple medicaments for use, and has simple and convenient operation.
Description
Technical field
The present invention relates to a kind of alkaline complex cleaning and washing agent, relate in particular to the complex cleaning and washing agent that a kind of cleaning membrane system contains organic fouling to Organic pollutants such as oils, colloid, tensio-active agent in the membrane for water treatment system.
Background technology
Continuous development along with pure water technology and waste water recycling technology; The application of membrane technique (comprising reverse osmosis membrane, nf membrane, ultra-filtration membrane, microfiltration membrane) in water treatment more and more widely; And the continuous deterioration at water source is to the higher requirement of normal operation proposition of film system; The stifled first obstacle that also becomes its operation of the dirt of film system, how reducing dirty stifled or dirty how effectively the cleaning after stifled is two research directions of concern the most in the present industry field.The principal pollutant kind of film system is: inorganic salt (like lime carbonate, calcium sulfate, permanent white), MOX (like iron), mineral colloid (like mud), mikrobe, organism, bacterium, mould, silicon etc.; Main clean-out system to these pollutents is: hydrochloric acid, phosphoric acid, Hydrocerol A, sodium hydroxide, EDTA, hydrofluoric acid etc.; But the cleaning performance of these medicaments is relatively poor, function singleness, drug effect are low, does not have all kinds of impurity are removed effect completely fully.
Summary of the invention
To above defective; The present invention provides that a kind of scrubbing effect is preferable, the drug effect scope is wide, can replace cleaning membrane system oil-containing that various medicaments uses, the complex cleaning and washing agent of tensio-active agent, colloid dirt, thereby thoroughly solves the dirty problem that can not effectively clean after stifled.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of cleaning membrane system contains the complex cleaning and washing agent of organic fouling, comprises by yellow soda ash, EDTA-4Na, Trisodium Citrate, X 2073 and pure water being respectively 15%, 25%, 15%, 1%, 44% formulated and under normal temperature, carry out chemical mixing and form solution according to the quality proportioning.
Beneficial effect of the present invention is: beneficial effect of the present invention is: remove the pollution of organism to the film system through multiple action, can reach good scrubbing effect; Can solve the infringement of multiclass pollutents such as inorganic salt, MOX to the film system simultaneously, the drug effect scope is wide; Can replace various medicaments to use jointly, easy and simple to handle.
