Polyacrylamide Treatment Process for Sewage Sludge

In recent years, with the continuous improvement of Chinese residents' living standards, the demand for meat, eggs, milk and other aquaculture products also increases, so a large number of sludge treatment needs are generated. Now, we will explain how to process sewage sludge with Polyacrylamide treatment.


In recent years, with the continuous improvement of Chinese residents' living standards, the demand for meat, eggs, milk and other aquaculture products also increases, so a large number of sludge treatment needs are generated.

Aquaculture sludge contains rich organic matter, and a certain amount of nitrogen, phosphorus, potassium and other nutrients, if properly handled, can be used as a good organic fertilizer in farm produce, the sustainable development, but if discharged directly without treatment, the sludge will not only pollute the environment, a strong smell, can also spread disease, is a waste of resources.

At present, the treatment method of aquaculture sludge on the market is mainly dewatering and reducing, but from the perspective of sludge dehydration, aquaculture sludge has the characteristics of long fiber, easy to block, and large mud volume, which makes it difficult for traditional sludge treatment equipment to effectively treat it.

In the face of many traditional sludge treatment equipment aquaculture sludge, polyacrylamide manufacturers put forward tips for you.

1. Screw extrusion is not easy to block

Aquaculture sludge treatment of the larger problem, was the result of long fiber machine jams, once happened, then affects the processing quality, light weight, as a direct result of damage to the machine, so to deal with good breeding sludge, the first thing to solve the congestion problem is the length of fiber, aquaculture sludge to pretreatment of resource utilization in the first place, at the same time through collecting liquid trough, Filtrate filled with organic matter and small granular sludge are pumped to the stacking screw machine for secondary treatment.

2. Small footprint and high efficiency

Aquaculture sludge production and fixed, but different from farms professional sludge treatment facilities, most farms are often not set when the design specially for the sludge dewatering place, therefore not suitable for large sludge processing machinery, capacity and rate of small devices in the area between, usually aquaculture sludge machine volume is small, high degree of integration, Small footprint, less civil construction required.

3. Automation is simpler

The farm has a lot of work and high labor intensity, and the virus and bacteria carried by the staff will also affect the safety of breeding. Therefore, more intelligent and simplified sludge dewatering equipment is needed to reduce the labor intensity of the staff and unnecessary animal contact.
