| titleOfInvention | A kind of waste plastics cleaning technique |
| abstract | A waste plastics cleaning technique for economic environmental protection, relates to resource reutilization and environmental technology field, and its processing step is as follows: 1) utilize all non-oily dirts of removal of surfactant waste or used plastics particle and more than 80% greasy dirt together; 2) cleaning sullage containing surfactant is concentrated precipitation, primary water reuse, neutral glar is used for fertilizer processing; 3) with the alkali lye of concentration 20% temperature 60-80 DEG C, the waste or used plastics particle after cleaning together is washed again; 4) alkaline sewage after two road cleanings is added flocculant precipitation, upper strata primary water mends the reuse of alkali Posterior circle, lower sediment mud acid neutralization, and oil reservoir material is used for fertilizer processing, and non-oily mud is for building embankment.The present invention adopts neutral surface active agent to wash to wash by force twice technique with caustic soda and cleans waste or used plastics particle, greatly reduce alkali charge and sewage load, reduce cost of sewage disposal, all effluent cycle utilize not outer row, mud makes full use of, process economics environmental protection, improves the utilization rate of resource, solves contaminated environment, pollution treatment high in cost of production problem in traditional handicraft cleaning. |
