Wastewater treatment station operation and dosing (PAM, PAC) problems

1, if you deal with wastewater treatment by batch, that is, you are full of a pool, a one-time dosing treatment, after treatment, a one-time discharge to the next treatment process, you can be a one-time dosing. Otherwise, you or according to eight hours of uniform dosing is better, after all, most of the sewage stations are continuous treatment, the side of the water into the side of the treatment, of course, is the average Xi dosing is better, the tank is not big enough, will not more than a few times with the drug? After running out and then allocate a can, will not?

2, after you change the pipeline is the wrong approach. Air can not be dissolved into the water, directly into the air-floatation tank, of course, only the effect of ordinary air mixing, can also be said that there is still a little air-floatation effect, but the bubbles are too big, it can be imagined that the effect must be very poor. Look at what you said is the most common dissolved air tank, you want to control the pressure balance of the tank water and gas, the best way to dissolve the air tank into the water pump into the water pipeline to open a small hole, connected to a gas pipe, directly from the inlet pipeline into the compressed air, the installation of a regulating valve to manually adjust the air flow to the most appropriate (if there are conditions, the installation of an air flowmeter is the best), adjusted to the dissolved air to the appropriate to be
