Abstract
In order to solve the problem that dirt on the wall of a filtering pool in a sewage treatment plant is difficult to remove, the invention provides a dirt removal agent for the wall of the pool in the sewage treatment plant and preparation and use methods for the dirt removal agent, and belongs to the field of detergents. The dirt removal agent consists of diluted hydrochloric acid, citric acid, EDTA-2Na and water. The dirt removal agent specifically consists of 3-5 parts by mass of diluted hydrochloric acid, 6-12 parts of citric acid, 80-90 parts of EDTA-2Na and 35-45 parts of the water. The preparation method is as follows: at the mass part ratio, diluted hydrochloric acid with the mass concentration being 8%-15%, EDTA-2Na powder and citric acid powder are added into an open container, the water is added, and stirring is performed to form uniform paste, namely the dirt removal agent. The use method is as follows: 30%-50% by mass of the water based on the dirt removal agent is added into the dirt removal agent, uniform stirring is performed, and a mixture is uniformly applied to the surface of a to-be-cleaned object and flushed away with clear water in 24-36 hours. The dirt removal agent is ecological, environmentally-friendly, efficient, nontoxic, and simple and convenient during actual use.
Description
Technical field
The invention belongs to sanitising agent field, be specifically related to a kind of sewage work pool wall dirt remover and preparation and application thereof.
Background technology
Sewage work is the major function undertaker of Water Environmental Pollution Control, in pollution of purifying waste water, play keying action.By the end of the year 2014, the urban wastewater treatment facility put into operation in the whole nation will be close to 4000, and general design processing power is more than 50,000,000,000 m
3/ d.An outstanding feature of sewage work is exactly that pond kind is many, and area is large: equalizing tank, acidizing hydrolyzation tank, preliminary sedimentation tank, aerated grit chamber, biochemistry pool, second pond, potassium permanganate composites, sand filter, uv sterilisation pond etc.In process of production, due to pollutant kind complicated component, the interaction of the metal ion in sewage, inorganic components, organism and microorganism secretion thing, there is black scale deposit in result, cause effluent quality to be deteriorated, affect production run on pool wall.Therefore, in day-to-day operation process, often regularly or aperiodically to remove these dirts.The washing agent that tradition uses has chlorinated lime, calcium hypochlorite, copper sulfate, bromogeramine etc., but these washing agent major parts are the composition such as strong acid, highly basic, have that corrodibility is strong, volatility is large, operation easier is high, length consuming time, lead disadvantageous effect not only to operator's physical and mental health, and cleaning performance is poor, scavenging period is long, cleaning efficiency is low, finally affects production run.Therefore, be necessary to develop the sanitising agent efficiently can removing sewage work's pool wall dirt.
Summary of the invention
In order to the problem that the filter tank pool wall dirt difficulty solving sewage work is removed, the invention provides a kind of sewage work pool wall dirt remover and preparation and application thereof.This Products Eco environmental protection, high effect nontoxic, simply effectively can remove the black dirt on pond pool wall and filter sand.
A kind of sewage work pool wall dirt remover, is made up of dilute hydrochloric acid, citric acid, disodium ethylene diamine tetraacetate (EDTA-2Na) and water; Concrete mass fraction is: 3 ~ 5 parts, dilute hydrochloric acid, citric acid 6 ~ 12 parts, EDTA-2Na 80 ~ 90 parts, 35 ~ 45 parts, water;
Preferably, in dirt remover, the mass fraction of dilute hydrochloric acid, citric acid, EDTA-2Na and water is respectively 4 ~ 5 parts, 8 ~ 10 parts, 85 ~ 88 parts and 38 ~ 42 parts;
Wherein, the mass concentration of above-mentioned dilute hydrochloric acid is 8% ~ 15%.
The preparation method of above-mentioned dirt remover is:
According to above-mentioned number proportioning, get respectively mass concentration be 8% ~ 15% dilute hydrochloric acid, EDTA-2Na powder and citric acid powder join in open container, then add water and stir into uniform mashed prod, namely obtain this product.
The using method of above-mentioned dirt remover is:
In dirt remover, add the water that quality is dirt remover quality 30% ~ 50%, stir, then by its uniform application at body surface to be cleaned, place after 24 ~ 36 hours, rinse with clear water and remove.
Principle of the present invention is: EDTA-2Na is a kind of good complexing agent, and it has six ligating atoms, has ligancy widely, almost can form stable inner complex with all metal ions.Citric acid is a kind of tricarboxylic acid, namely can by dirt acidifying, and solubilized ferric oxide and cupric oxide make it generate the complex compound of ironic citrate and copper again.Dilute hydrochloric acid by the acidifying of pool wall dirt, can remove pool wall surface attachments simultaneously.Dirt remover of the present invention is first by the acidifying of pool wall dirt, and metal ion is wherein stripped down by EDTA-2Na and citric acid by the pool wall dirt after acidifying, thus reaches the effect of cleaning pool wall.
Compared with prior art, its feature is in the present invention:
1, dirt remover ecological, environmental protective of the present invention, high effect nontoxic.The composition that in this formula, non-volatility is strong, nontoxic, without strong acid, only have a small amount of dilute hydrochloric acid, citric acid and complexing of metal ion agent EDTA-2Na.
2, simply efficient during the actual use of product of the present invention.Adopt the sanitising agents such as traditional toilet cleaner, high volatility, consuming time many, labour intensity is large, particularly for not easily manually-operated object and dead angle, dirt is difficult to remove, and easily article to be cleaned is shown structural failure (cleaning by instrument brute forces such as cleaning balls).And medicament only need be configured to pasty state by this formula, with instrument uniform application at body surface to be cleaned, carry out sufficient physical chemistry ion-exchange, rinse with clear water again, namely the object surface structure to be cleaned avoided with the powerful wiping of traditional medicament causes damages, alleviate labour intensity again, turn improve cleaning effect simultaneously.
3, through the dirt of product treatment of the present invention, its clearance rate reaches as high as more than 90%.
