The invention discloses a solid waste multi-stage classification treatment process. The solid waste multi-stage classification treatment process comprises the following steps that S1, sorting is carried out; S2, coarse crushing and fine crushing are carried out; S3, primary magnetic separation is carried out; S4, coarse screening is carried out; S5, fine crushing is carried out; S6, secondary magnetic separation is carried out; and S7, classification operation is carried out; wherein all the procedures in the step 1 to the step 7 are connected through conveying devices. The solid waste multi-stage classification treatment process comprises the steps of sorting, coarse crushing, fine crushing, primary magnetic separation, coarse screening, fine crushing and secondary magnetic separation, and the following two steps of operation can be carried out according to requirements after the secondary magnetic separation, wherein for the first case, tertiary magnetic separation and force crushing are carried out, and for the second case, winnowing is carried out, such that solid waste can be effectively treated, the cost can be reduced compared with an existing process while sufficient recycling is carried out, and popularization and development are facilitated.
Description
technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to a multi-stage classification treatment process for solid waste. Background technique [0002] Solid waste refers to solid, semi-solid, and gaseous items placed in containers that lose their original use value or have not lost their use value but are discarded or abandoned during production, living and other activities. , Articles and substances that are included in waste management according to administrative regulations. Liquid wastes that cannot be discharged into water bodies and gaseous substances placed in containers that cannot be discharged into the atmosphere. However, the existing solid waste treatment process cannot take into account both cost and effect, so it is very necessary to design a solid waste multi-level classification treatment process. Contents of the invention [0003] The object of the present invention is to provide a solid waste multi-s...
