1. The problem of the amount of treatment, because the content of starch solid waste in water is small, a large amount of water needs to be transported during the process, and the capacity of the filter press is relatively large, which results in a large workload. When the production volume of the factory increases, sometimes the sewage treatment will not affect the production.
2. Every day when the factory starts production, the starch and solids left in the pipeline and the tank often precipitated from the previous day of production shutdown. At this time, a large amount of water is needed for washing, and sometimes it is caused by solid matter. The pump is difficult to work and is damaged.
Faced with these two problems, the Dutch Parker environmental protection uses the characteristics of the peristaltic pump to provide a new concept of sewage treatment. First, the sewage is injected into a large sewage bucket, and the volume of the bucket is designed according to the workload. Then the sewage is allowed to stand for several hours, so that the solid starch can be precipitated to the bottom of the sewage bucket, causing the solid-liquid separation in the bucket, and then the viscous solid matter in the bottom of the bucket is directly transported to the sludge bag through the peristaltic pump. factory. * After the water in the bucket is treated slightly, it is recycled and reused in production.
American National Starch is the first to use such advanced treatment methods, and truly realizes the production efficiency and economic benefits brought by peristaltic pumps in production practice.
1. The investment of the filter press is omitted, and the sewage bucket is directly used to realize solid-liquid separation in the bucket. The peristaltic pump can deliver a large amount of solids and can therefore be poured directly into the sludge bag.
2. The energy consumption is greatly reduced. Due to the large amount of water as a carrier, the energy consumption of the centrifugal pump during the transportation process is mainly used to transport the medium. At the same time, the energy consumption of the filter press is mainly to separate the sludge from a large amount of water.
3. The reuse of a large amount of clean water not only saves electricity but also saves water consumption. Such a process is a very good idea, but in the design it is inevitable to provide a high demand for the pump to transport the sludge, that is, the medium can be transported with uncertain mucus and the medium with a large solid content. Peristaltic pumps just meet such delivery requirements, and other forms of pumps cannot solve both of these problems at the same time.
Peristaltic pump provides a new solution for starch wastewater treatment
The traditional starch sewage treatment usually takes the sewage directly into the filter press by a centrifugal pump, and after filtering, the starch solid waste is air-dried and packaged and then transported away. Such a process generally encounters two problems in actual use.
