Abstract
The invention discloses a cleaning agent, which comprises the following components in percentage by weight: 1.5-2.5 percent of sodium tripolyphosphate, 0.5-1.0 percent of sodium type EDTA (Ethylene Diamine Tetraacetic Acid), 0.2-0.25 percent of sodium dodecyl benzene sulfonate and water, wherein the pH of the cleaning agent is 10.5-11.5; and the percentage is weight percentage. The formula of the cleaning agent disclosed by the invention is screened specifically specific to a water recycling ultrafiltration membrane; and serving as a cleaning agent of a recycled water recycling ultrafiltration membrane, the cleaning agent has a good descaling effect, so that the application range of the recycled water recycling ultrafiltration membrane can be enlarged, the service life of the membrane is prolonged, and the water draining efficiency of a membrane system is increased.
Description
Technical field
The present invention is concrete relates to a kind of cleaning agent and application thereof.
Background technology
At first, middle water reuse can effectively solve the shortage of water resources problem, and is significant to the sustainable development that promotes agricultural production and national economy, and it is not enough greatly to alleviate water resource.
Secondly, middle water reuse has advantage economically than other water resource of development and use.The water producing cost of recycle-water is low, and this is because saved energy consumption cost and the capital cost of water resources taxes, remote water delivery.
The 3rd, be back to agricultural production and greening after the municipal sewage treatment, with bringing considerable environmental benefit.
The 4th, the membrane separation technique of " biochemistry+deposition+ultrafiltration technology " has been carried out efficient organic with biotechnology and has been combined, and gains great popularity with advantages such as its effluent quality are good, floor space is little, excess sludge is few, operational management is convenient.At present, membrane separation technique has obtained popularization and extensive use in middle water Treatment for Reuse field.
But in the use of middle water, water quality often presents ammonia nitrogen, oil content, characteristics that suspension content is high, has caused bigger pollution for milipore filter, has influenced water outlet efficient and quality.To this situation, just need the scavenger specially of various milipore filters, permeable membrane, and can be directed against the characteristics of various milipore filters, permeable membrane, remove organic matter and solid deposits such as the surperficial various greases of striping, biological substance, colloidal solid quickly and efficiently.
Summary of the invention
Technical problem to be solved by this invention is in order to overcome in the prior art, on middle water reuse milipore filter, to have sedimental problems such as grease, biological clay, colloidal solid, and a kind of cleaning agent and application thereof are provided.The prescription of cleaning agent of the present invention screens to middle water reuse milipore filter especially; The cleaning agent of water reuse milipore filter in its conduct; Descale effect is better, thereby the scope of application of water reuse milipore filter in can enlarging improves the service life of film and the water outlet efficient of film system.
Therefore, the present invention relates to a kind of cleaning agent, it comprises following each component: 1.5%～2.5% sodium phosphate trimer, 0.5%～1.0% sodium type EDTA, 0.2%～0.25% neopelex, and water; The pH of said cleaning agent is 10.5～11.5; Described percentage is mass percent.
Wherein, described sodium phosphate trimer is a composition commonly used in the cleaning agent, can be used as the pH conditioning agent, and what its content was preferable is mass percent 2%.
Described sodium type EDTA, promptly sodium type ethylenediamine tetra-acetic acid can be used to the solid suspension in the disperse water as high-molecular chelating agent, and preferable is the EDTA disodium salt.What its content was preferable is mass percent 0.8%.
Described neopelex can be used as surfactant, is used for removing the oily matter on the milipore filter, behind this material of interpolation, effectively raises the antiscale usefulness of cleaning agent among the present invention.What its content was preferable is mass percent 0.25%.
Described water can be this area water commonly used, and preferable is deionized water, and what its content was preferable is 100% to get final product for supplying mass percent, and better is 96.95%.
The pH value of cleaning agent of the present invention can be through adding the conventional pH conditioning agent in this area, regulates like NaOH etc., and what the pH value of described cleaning agent was preferable is 10.9～11.1.
Also can comprise the conventional additive in this area in the cleaning agent of the present invention, like isopropyl alcohol.
Cleaning agent of the present invention can promptly get like the liquid that each component simply is mixed to clarification according to the conventional method preparation of this area.
The invention further relates to the application of water reuse hyperfiltration membrane cleaning agent in the above-mentioned cleaning agent conduct.
Among the present invention, but above-mentioned each preferred feature promptly gets each preferred embodiments of the present invention in combination in any under the prerequisite of this area general knowledge.
Except that specified otherwise, raw material that the present invention relates to and reagent are all commercially available to be got.
Positive progressive effect of the present invention is:
1, the prescription of cleaning agent of the present invention is to carry out special optimum organization to middle water reuse milipore filter to obtain, and features high scale-removing effect can prolong the service life of ultrafiltration membrane system greatly, saves cost of equipment and operating cost.
2, cleaning agent stable performance of the present invention is nontoxic, with low cost.
