Description

Solid waste grading treatment device for environmental protection Technical Field The invention belongs to the technical field related to solid waste treatment, and particularly relates to an environment-friendly solid waste classification treatment device. Background With the rapid development of economy, the pressure of water resource shortage is increasing, and people finally realize that the consumption of water in society is beyond the range which natural circulation can bear. And the wide application of sewage treatment systems is a necessary choice for sustainable development of society. There are many suspended matters or floaters in the sewage, and these solid wastes are liable to affect the normal use of facilities such as water pumps, sewage equipment, etc., and the suspended matters or floaters in the sewage need to be removed before the sewage treatment is performed, which requires the use of a solid waste interception structure. The following drawbacks exist in the prior art for solid waste treatment: First, in the prior art, after intercepting solid waste in industrial wastewater, a rotary grating or a bailing device is usually simply lifted by rotation of a grating structure. When the solid waste leaves the water surface along with the grille and enters the upper area, the solid waste lacks an effective guiding and transitional structure, and is easy to drop randomly or accumulate at a local position due to posture change, gravity center deviation and the like, so that the continuous transfer and the stability of subsequent treatment of the solid waste are affected, and even the operation of equipment is interrupted when serious. Secondly, in the prior art, the solid waste in the industrial wastewater generally has the characteristics of high water content and strong deformability, and particularly fibrous solid waste and flocculated sludge. Most of the rotary grating or the scooping device in the prior art only realizes solid-liquid separation, and the solid waste only completes limited dehydration through natural dripping after leaving the water body, and the solid waste cannot be subjected to effective mechanical dehydration treatment in a separation stage, so that the water content of the solid waste entering a collecting or conveying link is still higher, and the energy consumption and the cost of the subsequent filter pressing, transporting or disposing procedures are increased. Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to provide an environmentally friendly solid waste classification apparatus which is more practical and valuable.
