When the sludge dewatering effect is not good, adjusting the dosage of agent is an effective solution strategy. The following are some specific adjustment methods and precautions:

First, determine the type of drug and dosage range

Drug type:

According to the nature of sludge and treatment needs, choose the appropriate sludge dehydrating agent and sludge conditioner. The commonly used sludge dehydrating agent is polyacrylamide (PAM), while the conditioner may include ferric chloride, lime, polyaluminum chloride, etc.

Dosage range:

The dosage of the agent should be determined according to the water content of the sludge, organic content, particle size distribution and other characteristics. In general, if the dosage is too low, the desired effect may not be achieved, while if the dosage is too high, the cost may be increased or the environment may be adversely affected.

The recommended dosage range can be determined by consulting relevant data or conducting small experiments.

Two, the method of adjusting the dosage of medicine

Gradual adjustment:

On the basis of the initial dosage, the dosage of reagent is gradually adjusted according to the effect of sludge dehydration. A small increase or decrease can be carried out first to observe the change in the dehydration effect.

Observation feedback:

In the adjustment process, it is necessary to closely observe the changes in the dewatering effect of the sludge, such as the moisture content and solid content of the sludge. At the same time, we should also pay attention to the consumption and cost of the drug.

Record data:

The dosage and dehydration effect after each adjustment were recorded for subsequent analysis and summary.

Three, precautions

Avoid overdosing:

Excessive dosage of chemicals may lead to an increase in the cost of sludge treatment and even have adverse effects on the environment. Therefore, the dosage of the drug should be strictly controlled in the adjustment process.

Uniform dosing:

In order to ensure that the agent is fully mixed with the sludge, a uniform dosing method should be used. This can be done by stirring or mixing equipment.

Periodic evaluation:

Evaluate the sludge dewatering effect and the dosage of chemicals regularly in order to adjust and optimize the treatment plan in time.

Consider other factors:

In addition to the dosage of chemicals, other factors that may affect the sludge dewatering effect should also be considered, such as the pretreatment method of sludge and the operating parameters of the dewatering equipment.

In summary, adjusting the dosage of reagent is one of the effective means to improve the dewatering effect of sludge. In the adjustment process, it is necessary to select the appropriate type and dosage range of agents according to the characteristics of sludge and treatment needs, and closely observe the change of dehydration effect. At the same time, it is also necessary to pay attention to avoid excessive injection, even injection and regular assessment.
