Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] When the system is running, the sewage is pumped from the adjustment tank to a simple filter to remove particles with a particle size greater than 10 μm, and then enters the raw liquid storage tank.

[0029] When the raw liquid enters the storage tank, the acid and alkali addition system is activated to adjust the pH value of the liquid in the storage tank to 6-6.5. When the liquid level in the raw liquid storage tank reaches the set height, the first-stage disc-type membrane column water treatment device system starts, and the high-pressure plunger pump pumps the raw liquid into the disc-type membrane column water treatment device system. The purified water produced by the first-stage device system directly enters the second-stage disc-type membrane column water treatment device system, and the concentrated liquid produced circulates in...

Abstract

Treatment method of disc type column membrane water, is the immediate processing of high concentration sewage to achieve the required emission standards, which selects processing options in series, parallel, primary or secondary treatment modalities according to the water quality and emission standards. The treatment method of disc type column membrane water is used in combination with other processes, as the final treatment step before discharge to ensure reliable standards of high concentrations of sewage treatment. The treatment device of disc type column membrane water can be connected in series or parallel alternately with flexible operation mode. Device can be designed to be connected in series or parallel operation mode according to the requirements, to achieve less volume of water and higher standards of water quality in series operation mode, and larger volume of water and lower emission standards in parallel operation mode, meeting the requirements of different water volume and water quality.

Description

technical field [0001] The invention discloses a disc-type membrane column water treatment method and device, relating to a sewage and waste water treatment method and device, belonging to the technical field of environmental protection and treatment, and in particular to a high-concentration sewage treatment method and device. Background technique [0002] With the rapid development of industry and the continuous improvement of people's living standards, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. Due to the more complex components of wastewater, some of which are toxic, wastewater treatment is more difficult and more important. [0003] For several typical high-concentration organic wastewater, such as coking wastewater, pharmaceutical wastewater, textile / printing and dyeing wastewater, petroleum / chemical wastewater, landfill leachate, e...
