Food factory wastewater zero discharge equipment dosing method of running is what?
Food industry provides our lives with a large number of high quality and delicious food, but the industry in the process of production will discharge a large amount of sewage, if not handled in time, in the sewage could flow into the food production process, the influence of food hygiene.
Food processing industry to sewage processing food factory, the first thing to understand the source of sewage and wastewater composition, then targeted on this kind of wastewater treatment, and it can guarantee the effect of sewage treatment.
In the food factory wastewater zero discharge equipment operation process need to add a certain amount of reagent to guarantee the effect of sewage treatment.
To introduce the next food factory wastewater zero discharge method for operating equipment dosing.
1, first of all, open the inlet valve in the mixing barrel in the industry of drug dissolved in a certain amount of water, start the mixer is put inside the mixing barrel after a certain amount of potions, polymer coagulant to stir 5 & ndash;
10 minutes, coagulant aid to stir about 30 minutes, stirring after open the mixing barrel of hydraulic valve, metering pump valve, when run the sewage pump can activate metering pump for drug delivery.
When a pharmacy after completion can be dispensed to another stirring barrels of water. Set aside.
2, dosing pump with sewage pump, dosing pump according to the flow of electromagnetic flowmeter input signal by frequency converter automatically adjust the dosage.
Note: 1, when mixing into a bucket of water and additive agents in the mixing barrel need to mix another bucket of produced liquid valve closed.
3, when the need for small wastewater treatment equipment
parts of dosing device for repair please close the relevant valves, when need to stir barrels for repair, please open the vent valve.
Above is the food factory wastewater zero discharge equipment dosing problems need to pay attention to the use of, hope to help you practice.
If you have not understand problem.
