Sewage treatment equipment is mainly dealing with pollutants are organic matter, suspended solids, pathogens, etc., if the water directly into the water, not only will the water quality of the water black hair, and will make the water rich in nutrients Resulting in a large number of algae growth, fish death, surface water hardening, destruction of the ecological balance of water.


If you want to live in the sewage treatment, then the standard after the discharge, you can achieve water conservation, eliminate pollution, protect the environment, there is a good protection of environmental and social benefits.

Precautions:

1. The speed and time of stirring the polyacrylamide PAM solution

It is well known that stirring polyacrylamide is generally mechanically agitated. The mechanical stirring speed has a great influence on the preparation time of the solution, but the excessive stirring speed will cause the degradation of the polyacrylamide solution, so that part of the polyacrylamide long chain fracture, affecting the settlement effect, it must strictly control the mechanical stirring speed. In the 1m diameter mixing tank speed should not be greater than 800rpm, 1.5 ~ 2m diameter stirring poke speed should not be greater than 600rpm. Increase the temperature of the stirring solution can reduce the dissolution time, but the maximum water temperature does not exceed 60 ℃, otherwise it will cause degradation, affecting the use of results.


2.PAM solution preparation must be a special equipment

PAM solution must be prepared using special equipment, and strictly prevent the use of other coagulants together, or in a cast pool pool together, otherwise the two agents will produce copolymer precipitation, not only affect its effect, and easy to plug the dosing equipment The


3. The metering device must be calibrated with solution

Since the PAM solution is a drag reducing agent, the difference with the calibration value of the water. Therefore, polyacrylamide solution metering equipment must be calibrated with a solution, shall not be calibrated with water. Otherwise it will increase the dosage of polyacrylamide, both to improve processing costs, but also cause unnecessary consequences.


4. Dosing concentration

PAM solution dosing concentration of the more dilute, the better the effect, the more dilute the concentration of the solution can make the solution in the water quickly expanded, fully mixed to prevent excessive concentration of colloidal protection phenomenon, the impact of the effect. But the concentration is too thin will cause a huge dosing equipment. General dosage of 0.5% to 1% is appropriate, the preparation of the concentration of 2% is appropriate.


5. Dosing in batches

In the use of polyacrylamide treatment of high turbidity water, the batch administration is better than the flocculation effect of one administration. Such as the muddy surface surface velocity for the comparison value, the former for the latter more than 3 times. The so-called batch administration, is the dosage is divided into two parts were added to the water, the first part of the flocculant to join and then quickly mixed with water, separated by 1 ~ 2min, adding another part of the flocculant, and then quickly mixed with water. As the batch administration can avoid excessive flocculant concentration combined with sediment, resulting in the consequences of closed groups of active groups, which can achieve better results. The proportion of batches of drugs, generally first plus 60%, and then cast 40% better. In the case of water supply engineering design conditions, should be used as much as possible in batches of measures.


6. Dump order

When PAM is used as a coagulant, the general dosing sequence is after the addition of the coagulant. If used alone as a high turbidity flocculant, you should first add polyacrylamide flocculant, otherwise it will affect the use of results. In the design of the dosing should take into account the change in the order of the measures.
