In today's era when environmental awareness is increasing day by day, sewage treatment has become the focus of attention from all sectors of society. In the process of sewage treatment, sludge treatment has always been a thorny problem. The traditional sludge treatment methods have many drawbacks, such as poor dewatering performance, high treatment costs, and potential threats to the environment. However, with the continuous advancement of technology, a new type of product - sludge efficiency enhancer - has emerged, bringing new hope to sludge treatment.
Sludge enhancer is a kind of chemical agent that can change the surface structure of sludge, reduce the solid surface load of sludge, lower the specific surface area of sludge, and destroy the structure of bacteria. Its main components include inorganic compounds, sludge surface structure modifiers, degreasing agents, cell wall disruptors, sludge surface treatment agents, sludge stripping agents, etc. These components work in synergy with each other, endowing the sludge enhancer with numerous unique advantages.
Firstly, sludge enhancers perform exceptionally well in reducing the moisture content of sludge. Combined with the plate and frame sludge press, it can reduce the moisture content of sludge from over 90% to 40%-60%, fully achieving sludge reduction. This not only significantly reduces the volume and weight of subsequent sludge treatment, lowers transportation and disposal costs, but also creates favorable conditions for the resource utilization of sludge. For instance, in a certain municipal sewage treatment plant, after the application of sludge enhancers, the volume of sludge was reduced by nearly half, and the subsequent costs of landfill and incineration were also significantly lowered.
Secondly, sludge enhancers can significantly enhance the efficiency of sludge pressing. When used in conjunction with a plate and frame filter press, it can effectively enhance productivity, increase the sludge pressing efficiency by 100% to 500%, and at the same time reduce the sludge pressing cycle. In some industrial sewage treatment facilities, the sludge pressing process, which originally took a long time to complete, has been shortened several times after the use of sludge enhancers, significantly enhancing production efficiency and meeting the enterprises' demand for efficient production.
Furthermore, the sludge efficiency enhancer can also reduce the frequency of filter cloth replacement for mechanical equipment, saving the operating costs of enterprises. Due to its special composition and working principle, it causes less damage to the filter cloth during the sludge treatment process, thus extending the service life of the filter cloth. This is undoubtedly a considerable cost savings for those enterprises that need to frequently treat sludge.
In addition, the application scope of sludge enhancers is very wide, suitable for the dewatering and disposal of sludge in various industries such as daily life, printing and dyeing, papermaking, electroplating, chemical engineering, and leather. Whether it is a municipal sewage treatment plant or various industrial and domestic sewage treatment facilities, the sludge treatment effect can be improved by using sludge enhancers.
When using sludge enhancers, the operation is also relatively simple. The prepared sludge is injected into the filter chamber of the filter press at a pressure of about 1.0 mpa, which is conducive to efficiently filtering out the free water in the sludge. When the accumulated sludge in the filter chamber reaches the designed capacity of the filter press, it enters the high-pressure pressing stage. When the chemical conditioning achieves a good effect, high-pressure feeding and high-pressure pressing can shorten the time of the entire pressing section and improve production efficiency. At the same time, the fully automatic unloading and the reverse blowing and washing of the filter medium (filter cloth) are completed simultaneously, which not only reduces the labor intensity of the control workers but also improves the efficiency of the completed actions, maintaining the effect of the filter cloth in intercepting sludge and permeating water.
In conclusion, as an innovative sludge treatment product, the sludge enhancer has brought new hope to the sewage treatment industry with its outstanding performance and wide application range. It not only can effectively solve the problems in sludge treatment, reduce treatment costs and improve treatment efficiency, but also conforms to the concepts of environmental protection and sustainable development. It is believed that in the future, with the continuous improvement and wide application of technology, sludge enhancers will play a more important role in the field of sewage treatment and make greater contributions to the improvement of our environment.
