At present, the problem of "high cost and low efficiency" in sludge treatment of domestic sewage treatment plants is prominent - under traditional processes, the moisture content of sludge dewatering often reaches 80%, and the annual disposal cost accounts for more than 30% of the total operating cost. Moreover, the conditioning period is long and the equipment utilization rate is low, which is prone to cause the risk of "sludge tank swelling". The application of sludge enhancers provides an efficient solution to break this deadlock.

From the perspective of cost reduction, the sludge efficiency enhancer, through the effect of "charge neutralization + colloid stabilization", can reduce the dewatered moisture content to 65%-70% and decrease the sludge volume by 40%-50%. Take a sewage treatment plant with a daily processing capacity of 100,000 tons as an example. The daily sludge output can be reduced from 80 tons (with a moisture content of 80%) to 40-48 tons, saving over 1 million yuan in annual transportation costs and reducing the consumption of drying heat energy by 35%. Some of the enhancers can also increase the calorific value of sludge, facilitating incineration power generation to replace coal, and saving about 800,000 yuan in costs annually.

The rapid reaction characteristic of the sludge enhancer reduces the conditioning time from 2 to 3 hours to 30 to 60 minutes. After being applied in a certain northern sewage treatment plant, the single cycle of the plate and frame filter press was reduced from 4 hours to 2.5 hours, and the daily processing batch increased by 50%. It can meet the treatment demand without the need for new equipment.

In actual cases, after a 200,000-ton-per-day sewage treatment plant in the east introduced a sludge efficiency enhancer, its annual disposal cost dropped from 12 million yuan to 6.8 million yuan, electricity costs were saved by 350,000 yuan, and the overall cost decreased by 45%. At the same time, the problem of "sludge accumulation" during the rainy season was solved, and the incineration power generation increased by 25%.

Under the impetus of policies, sludge enhancers are accelerating their iteration. In the future, they will develop towards "low dosage and high environmental friendliness", and will also expand into the field of industrial sludge treatment, providing integrated services of "chemicals + operation and maintenance", continuously empowering sewage treatment plants to reduce costs and increase efficiency, and promoting the industry's transformation towards green and efficient development.
