Embodiment Construction
[0016] The present invention provides a three-stage treatment system for papermaking white water. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0017] see figure 1 , The invention provides a papermaking white water three-stage treatment system. In this paper, the pumps, pools, tanks and other equipment are named differently, the purpose of which is only for convenience of explanation, not to limit the present invention. The arrows in the figure show the flow direction of materials during normal operation.
[0018] The papermaking white water tertiary treatment system includes a water inlet main pipe 91, a white water multi-disk machine 11 connected to the water inlet main pipe, a turbid white water p...

The invention discloses a papermaking white water three-stage treatment system which comprises a water inlet main pipe, a white water multi-disc machine connected with the water inlet main pipe, a turbid white water tank, a clear white water tank, an ultra-clear white water tank, a first air flotation machine, a first dissolved air pump, a first dissolved air tank and a gravity water sieve, a turbid white water outlet of the white water multi-disc machine is connected to a turbid white water pool, and a clear water outlet of the white water multi-disc machine is connected to a clear white water pool; an ultra-clean water outlet of the white water multi-disc machine is connected to an ultra-clean white water tank, and an outlet of the ultra-clean white water tank is connected to an inlet of the first air flotation machine through an ultra-clean white water pump; the first air flotation machine is connected with a first coagulant adding pump; a water outlet pipeline of the first air flotation machine is connected to a gravity water sieve; and the gravity water sieve is connected to a deep treatment water tank. By arranging the white water multi-disc machine, the first air flotation machine, the gravity water screen and other equipment, the purification degree of the papermaking white water is improved, and the device can replace clean water of most workshop sections to be recycled.
Description
technical field [0001] The invention relates to the technical field of papermaking, in particular to a three-stage treatment system for papermaking white water. Background technique [0002] During the papermaking process, a large amount of white water generated in the wire section needs to be recycled. In the prior art, the white water is usually processed by a multi-disk machine to obtain turbid white water, clear water and ultra-clear white water, thereby realizing white water recycling. However, in actual production, the treatment depth of ultra-clear water has not reached the level used to replace normal clean water, and the efficiency of white water recycling needs to be further improved. [0003] It can be seen that the prior art still needs to be improved and enhanced. Contents of the invention [0004] In view of the deficiencies of the prior art above, the purpose of the present invention is to provide a three-stage treatment system for papermaking white water,...
