Factors influencing the biochemical degradation of LAS

Factors influencing the biochemical degradation of LAS

Physical and Chemical Properties

Appearance under normal temperature as milky, liquid material; when it is warmed, it becomes transparent liquid. Soluble in water while insoluble in chloroform. Air bubbles would be generated when in water, which is of such functions as dispersing, decontamination and reducing surface tension, etc. It is easy to form stratified layer after long storage time while the chemical properties do not change, so it is better to use after thorough stirring.

The temperature

Microbial growth need to be in the right temperature, only in the appropriate temperature, the degradation rate of LAS was biggest. Optimum growth and microorganism decomposition temperature at 30 ℃, and its activity in a certain temperature range varies with temperature

Increased. Studies have shown that at 20 ℃, linear alkyl benzene sulfonate (LAS) degradation in the aquatic system speed is (1.5 ~ 3.5 ℃) 20 times. Chemical reaction rate is affected by temperature. So the temperature can affect LAS biochemical degradation.

PH

In general, the pH of water, microbial activity has a direct impact. Suitable pH range of different microorganisms. Degradation of LAS microorganisms such as bacteria, actinomyces, pH change will cause the change of cell charge, at the same time will affect the activity of enzyme in cells. However, for a river, the influence of pH value on the LAS is not very obvious.

The initial concentration of LAS

Pollutant itself to microbes, generally speaking, there are certain toxicity, and the toxicity increased with the increase of pollutants concentration increased. Studies show that when the concentration of LAS > 10 mg/L, the inhibition of its degradation is obvious. And studies have shown that LAS can affect aerobic degradation of organic matter in PH self-adjusting ability. When the initial concentration of LAS is greater than 20, then stop the aerobic degradation of organic matter in the PH of self-adjusting ability, reduce microbial activity.

Effect of dissolved oxygen
Most of the LAS aerobic degradation is mainly to increase the dissolved oxygen concentration , can significantly increase the degradation of LAS . Aerobic biodegradation of LAS mainly contains three kinds of mechanism: ( 1 ) by ω- oxidation of the terminal methyl group on the alkyl chain by oxidation of β or α- oxidation of long- chain molecules that form short -chain sulfonic disconnect benzene carboxylic acid ; ( 2 ) oxidation of the benzene ring to open crack action ; ( 3 ) de- substituted sulfonic acid salt removed by this process . However, these three mechanisms on the role of sequence researchers have not yet reached consensus view . Studies have shown LAS can be degraded under anaerobic conditions .

Other effects of coexisting substances
Biodegradation of LAS will be affected by the presence of other pollutants , when the water there are other biodegradable organic pollutants , will produce inhibition of microbial degradation of LAS or catalytic role in some of the water -binding makes the LAS chemically changed thus changing the biochemical degradation of LAS . LAS primary pollutants into the water after the other pollutants combine to form with a certain degree of dispersion of colloidal particles of industrial wastewater and domestic wastewater physicochemical and biochemical characteristics has a significant impact , and produce potentially dangerous.

Protection of hydrazine hydrate

Protection of hydrazine hydrate

Hydrazine hydrate is a very important chemical raw material in our daily life, in all fields has its shadow, in thermal power plant are anti-corrosion additives, also azo initiator, in agricultural chemical products and pharmaceutical products is also an important part. In industrial production is also have a lot of application.

In fact, in the pharmaceutical industry, hydrazine hydrate is a critical part of the production of various kinds of drugs, which is usually drug toxicity is we all said. Also often see in the consumer goods industry, it is also a kind of foaming agent. As well as our agrochemical industry. Urea is generated in the process of hydrazine hydrate. Hydrazine hydrate or rocket fuel and the formulation of the product. So hydrazine hydrate when can't get effective control is very damaging. If in the process of production have a large number of hydrazine hydrate leak what to do.

The first thing to do is to evacuate leakage pollution area personnel to safe areas, no irrelevant personnel enter the contaminated area, suggested that the emergency response personnel wear self-contained breathing apparatus, wear chemical protective clothing. Don't direct contact with the leakage, plugging in ensuring safety situation. Spray water, reduce evaporation. It incombustible adsorbent with sand or absorbed, and then collected to disposal of waste disposal places. You can also use a lot of water to rinse, diluting the wash water into wastewater system. Such as a large number of leakage, use of cofferdam asylum, and then collect, transfer, recycling and harmless treatment after the waste.

The harm of hydrazine hydrate is very big; if not timely processing waste pollution is extremely serious leakage. Waste liquid chlorine dioxide foam separation process and hydrazine hydrate by chlorine dioxide foam separation device, chlorine dioxide foam separation was studied in hydrazine hydrate class waste liquid treatment effect. Through the experiment focuses on the waste water pH, chlorine dioxide dosing quantity and reaction time on the influence of parameters on the effect of wastewater treatment. The optimum reaction conditions (i.e. pH value of 10, chlorine dioxide in waste water per liter dosing quantity is 5 mg / 1000 COD, the reaction time is 3 h) under the reaction, the original liquid waste (COD value of 30000-30000 mg/L, total ammonia nitrogen is 2500 ~ 2700 mg/L) after processing the COD removal rate reached 99%, ammonia nitrogen removal rate reached more than 96%.

If direct contact with hydrazine hydrate to clothing, immediately remove contaminated clothing and thoroughly rinse immediately with flowing water.

If contact with eyes, immediately filed a eyelid, with flowing water or saline flush at least 15 minutes. And then go to the hospital quickly.

If you accidentally splashed into his mouth, the most effective is to drink milk, or eat an egg, and then hurried to the hospital.
