There are problems in Yingtan printing and dyeing water treatment: when the nitrogen removal effect of A2/O process is good, the phosphorus removal effect is poor, and vice versa, it is difficult to achieve good deoxidation and phosphorus removal effect at the same time. However, when there is a large amount of salt in the anaerobic section, the denitrifying bacteria will denitrify with organic matter as the carbon source, and start the anaerobic release of phosphorus after the complete nitrogen removal, which makes the effective volume of anaerobic release of phosphorus in the anaerobic section large, so that the phosphorus removal effect is poor, but the nitrogen removal effect is poor.
Yingtan printing and dyeing water treatment is a salt composed of acetic acid and sodium ion, 10% - 25% solution, which is widely used to supplement carbon source for denitrification and denitrification in sewage treatment, and has domestication effect on denitrification. It is an excellent sewage carbon source agent.
Therefore, when the influent dissolved organic matter is insufficient and the nitrogen removal requirements are high, it is necessary to supplement chemistry to provide the carbon source required for denitrification. 2. Sudden increase of wastewater volume: With the increase of plant production, a large amount of sewage generated will overload the original old process and easily exceed the standard.
Yingtan printing and dyeing water treatment Sanshui appearance: slightly yellow, no suspended solids.
Density: 1.15
20%, COD 160000 mg/L;
Content 25%, COD 200000 mg/L;
Advantages for sewage treatment:
1. Shortening the acclimatization time can shorten the stagnation period and quickly adapt to new strains.
2. Tolerance to external adverse conditions such as salinity and temperature Resistance to impact such as PH value.
3. Load, rich nutrition, strong metabolic activity, fast synthesis of new cells, and growth rate of denitrifying bacteria can withstand high load
4. In the current sewage treatment, the denitrification process with external carbon source is under construction or operation in many sewage plants in China. Although it is recognized as an external carbon source with low price, it is used because of its toxicity. Sodium acetate is becoming a substitute carbon source that is widely used. Sodium acetate is nonflammable and explosive.
The content of sodium acetate is flexible, and different contents can be provided according to the process of the user.
Check whether the aeration pipeline is blocked or leaked. Repair or replace faulty parts. Mixing fault: fault phenomenon: the mixing equipment does not operate normally, and the sludge cannot remain suspended. Troubleshooting: check whether the power supply, motor and transmission device of the mixing equipment work normally. Check whether the blades of the agitator are damaged or stuck. Transportation: tank car, ton barrel, 25kg/small barrel. Dyeing water treatment
