Mante environmentally-friendly stone factory special polyacrylamide and sand washing plant special polyacrylamide is deeply loved by customers. It is derived from the company's analysis of water quality. According to the analysis in the stone processing industry, the mined stone needs to be cut and polished. Cutting and water milling processes will produce a large amount of sewage. If the natural settling time is slow and the problem cannot be solved, it should be solved by professional polyacrylamide precipitation + filtration produced by Henan Zhongqiao. It can handle the sewage in the stone factory very well. This is only a solution to the problem of suspended solids. If there is organic pollution, other treatments must be added. In the processing of stone, the polyacrylamide (pam) solution can improve the rotation speed of the cutting machine when cutting the stone, accelerate the cutting time, and can be used for stone waste water treatment. Protect environmental pollution and reduce wastewater discharge.
What kind of flocculant should I use for the muddy water in the sand washing plant? If the sand mud flow washed out by the sand washing plant is directly discharged, it will pollute the river water. Banning the sand washing plant will cause great inconvenience to people's production and life. At this time, effectively treating the muddy water of the sand washing plant has become a top priority. Anionic polyacrylamide produced by Gongyi Guangfeng Water Purification Material Co., Ltd., which is mainly used for clarification and purification of circulating water. Its water solubility is good, the amount is very small, generally only need to add 0.01~10ppm (0.01~10g/m3), you can see the obvious effect.
What is the main working principle of anionic polyacrylamide in sand washing plants? For this kind of industry, it is usually applied to the separation of wastewater treatment and mud. Because of the low level of contact, many people do not understand this industry. After our research and review, we outline the working mechanism of anionic polyacrylamide for sand washing plants.
The choice of anionic polyacrylamide, the treatment of sand washing wastewater is actually the separation of muddy water. The water obtained after the separation is recycled and reused in the sand washing. The anions we usually use separate the mud by the action of flocculation and sedimentation. First of all, the characteristics of the mud depend on its composition, and it is related to the local geological conditions. The general characteristic is that the mud is yellowish in appearance, uniform and sticky, and does not stratify for a long time. The specific gravity is between 1.20 and 1.46 (including the specific gravity of yellow sand) 1.6); mud content 20% ~ 30%, PH value: 6 ~ 7. These muds are derived from construction piling, sand fields, tunnel caves, mine tailings, etc.
The above working mechanism is as follows: the muddy water is collected into the sedimentation tank through the pipeline, and is pretreated by the mud dewatering machine to remove most of the fine sand and part of the mud in the muddy water, and the filtrate enters the secondary settling tank through the drainage system. The muddy water in the secondary sedimentation tank is suspended mud, and the difference in specific gravity from the water is very small. It must be treated with flocculant. After the muddy water is treated by the dehydrator, the mudstone removal rate is over 95%, and the water in the clear liquid pool It can be directly returned to the sand washing system to achieve zero emissions.
The main purpose of wastewater treatment is to meet the standards, achieve zero emissions, and reduce costs. The use of anionic polyacrylamide sand washing plant wastewater treatment and mud separation has significant effects and low cost. Cationic polyacrylamides can also be selected depending on the application in various fields.
