Sewage treatment system, control method and sewage filter-pressing-free treatment method

Abstract

The invention relates to a sewage treatment system, a control method and a sewage filter-press-free treatment method. The sewage treatment system comprises a sand-water separation tank, a transfer tank, a sedimentation tank, a stirring tank, a first plunger pump, a round roller screen and a high-level tank which are sequentially connected through pipelines, and a clear water cleaning mechanism isfurther arranged between the first plunger pump and the round roller screen; the sewage treatment system further comprises an electrical control circuit; and the sewage treatment system is small in work amount and high in operability, the filter pressing and transferring processes of sewage treatment are omitted, and the sewage treatment cost and manpower are reduced. The technology enables the whole process to be more reasonable, efficient, convenient and environment-friendly.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment system and a control method for the sewage treatment system, and also relates to a sewage treatment method realized by using the sewage treatment system without pressure filtration. Background technique [0002] After polishing and edging of ceramic tiles, a large amount of sediment will be produced, and these sediments can be reused as raw materials in the production process. The separation of sediments during sewage treatment has always been costly. The traditional sewage treatment mode It is to add flocculant-polyacrylamide and polyaluminum chloride to the sewage, and then introduce the flocculated sewage into the transfer tank, use the sewage pump to pump the sewage into the sedimentation tank for sedimentation, and use the plunger pump to pump the settled mud After entering the filter press, press filtration, store the squeezed mud in the silo, and then tra...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a sewage treatment system that solves the problems of high cost of sewage treatment by filter press technology, large labor input, high equipment failure rate, high maintenance cost, and poor storage and transportation environment. Another purpose of the present invention is to provide An environmentally friendly and efficient control method for a sewage treatment system that avoids sewage pressure filtration and mud transfer and provides a sewage treatment method without pressure filtration
