Description

Novel sand-water separator Technical Field The application relates to the technical field of sand-water separation, in particular to a novel sand-water separator. Background In the production field of companies, coal sewage and rainwater are orderly gathered to a production sewage treatment system through a planned drainage ditch network. The water resources reaching the treatment standard are endowed with new life, one part of the water resources are used as field environment-friendly water for spraying dust fall, greening irrigation and the like on the roads of the plant area, the water resources play a role in improving the environmental quality of the plant area, and the other part of the water resources are reserved as fire-fighting water, so that key water source guarantee is provided when the emergency fire is handled. The recycling mode for changing sewage into valuable not only effectively reduces the pressure of sewage discharge on the environment, but also realizes the efficient and repeated utilization of water resources, and fully shows the sustainable development concept of green development and resource conservation practiced by companies in production operation. In the current sewage treatment practice, the water quality purification is mainly carried out by adding polyaluminium chloride (PAC), polyacrylamide (PAM) and alkali. However, the method is limited by the existing treatment process, even though the effluent is treated by the medicament, a large amount of impurities and solid suspended matters remain, the impurities are easy to cause problems of pipeline blockage, equipment abrasion and the like after entering the on-site water using equipment along with the reuse water, the running stability and the service life of the equipment are seriously affected, frequent equipment faults greatly increase the equipment maintenance frequency, the maintenance cost is high, and the double dilemma of technical bottlenecks and economic burden is formed, so that the method explores an efficient and economic solid-liquid separation technology, realizes thorough removal of impurities and solid matters in sewage, becomes a key technical problem for guaranteeing stable running of the on-site water using equipment and reducing the operation and maintenance cost, and is a urgent need for the industry to develop intensive researches and technical breakthroughs.
