Description
Technical Field
The utility model relates to the technical field of water treatment, in particular to full-automatic folding point chlorination equipment.
Background
The break point chlorination method is a chemical denitrification process in which chlorine or sodium hypochlorite is introduced into wastewater to oxidize NH3-N in the wastewater into N2. When chlorine gas is introduced into the wastewater to reach a certain point, the free chlorine content in the water is the lowest, and the concentration of ammonia is reduced to zero. When the chlorine gas passing through the water exceeds this point, the free chlorine in the water increases. This point is therefore called the break point and the chlorination in this state is called the break point chlorination. The actual chlorine amount required for treating ammonia nitrogen wastewater depends on the temperature, the pH value and the ammonia nitrogen concentration. 9-10 mg of chlorine is needed for oxidizing each mg of ammonia nitrogen. The pH value is the optimal reaction interval between 6 and 7, and the contact time is 0.5 to 2 hours.
The effluent treated by the break point chlorination method generally needs to be subjected to antichlorination by using active carbon or sulfur dioxide before being discharged so as to remove residual chlorine in the water. About 0.9 to 1.0mg of sulfur dioxide is required for 1mg of residual chlorine. Hydrogen ions are generated during the antichlorination, but the pH value drop caused by the hydrogen ions is generally negligible, and the ammonia removal mechanism by the break point chlorination method is as follows:
Cl 2 +H 2 O→HClO+HCl
NH 3 +HClO→NH 2 Cl+H 2 O
NH 2 Cl+HClO→NHCl 2 +H 2 O
NHCl 2 +HClO→NCl 3 +H 2 O
the most outstanding advantage of the break point chlorination method is that the treatment rate can reach 90% -100% by correctly controlling the chlorine adding amount and homogenizing the flow, the treatment effect is stable, and the influence of water temperature is avoided. This method is particularly attractive in cold areas, and at the same time, the waste water is disinfected. For wastewater with low ammonia nitrogen concentration (less than 50 mg/L), the method is economical.
The break point chlorination method has the advantages of tighter control on the chlorine adding amount and higher precision requirement. The existing adding mode is generally and directly amplified according to the calculated amount, and the adding amount is adjusted according to the feedback of the ammonia nitrogen detector for final drainage during engineering debugging. The dosing mode can not realize automatic accurate control, manual adjustment is needed, accuracy is poor, manual labor capacity is high, ammonia nitrogen removal effect can not be guaranteed, and ammonia nitrogen in water is high and low in time, so that stable standard reaching can not be guaranteed.
