Embodiment 1

[0017] A printing and dyeing sewage treatment method, mainly comprising the following steps,

[0018] 1) Decompose, put the printing and dyeing sewage into the fermentation tank, and add microorganisms to make the organic matter in the printing and dyeing sewage ferment and decompose;

[0019] 2) Classification, by filtering, sieving out chemical materials that cannot be fermented and decomposed, and cleaning them up;

[0020] 3) pressure filtration, the sieve residue is filtered through a filter press, wherein a filter membrane is used to separate solid substances from liquid substances;

[0021] 4) Disinfection, limestone disinfects solid matter;

[0022] 5) Filtration, using activated carbon to filter liquid substances;

[0023] Through the above steps, the garbage can be effectively disposed of.

Embodiment 2

[0025] A printing and dyeing sewage treatment method, mainly comprising the following steps,

[0026] 1) Decompose, put the printing and dyeing sewage into the fermentation tank, and add microorganisms to make the organic matter in the printing and dyeing sewage ferment and decompose;

[0027] 2) Classification, by filtering, sieving out chemical materials that cannot be fermented and decomposed, and cleaning them up;

[0028] 3) pressure filtration, the sieve residue is filtered through a filter press, wherein a filter membrane is used to separate solid substances from liquid substances;

[0029] 4) Disinfection, adopting calcium hypochlorite to disinfect solid matter;

[0030] 5) Filtration, using diatomaceous earth to filter the liquid substance;

[0031] Through the above steps, the garbage can be effectively disposed of.

Abstract

The invention relates to a printing and dyeing sewage treatment method, belongs to the field of environmental protection, and aims to reach the purpose of effective treatment of garbage. The printing and dyeing sewage treatment method mainly comprises the steps of decomposition, classification, press filtration, disinfection and filtration, and the garbage can be effectively treated. Chemical materials which cannot be fermented and decomposed are effectively separated for reuse; treated water has no impurities and no peculiar smell, can be used as special water for flushing toilets, as well as special water for irrigating flowers, grass and trees. The treatment method is scientific and reasonable, the processing efficiency is high, the comprehensive benefit is good, the method is simple, and the utilization rate is high.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a method for treating printing and dyeing sewage. Background technique [0002] The printing and dyeing industry produces a lot of sewage, which has become an extremely difficult industrial disease to overcome. At present, chemical treatment or direct sun exposure are mainly used. The former is expensive, while the latter occupies a large amount of land and is prone to pollute groundwater. Nowadays, it is very important to take effective treatment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a printing and dyeing sewage treatment method to achieve the purpose of effectively treating garbage. [0004] In order to solve the above technical problems, the technical solution adopted in the present invention is: a printing and dyeing sewage treatment method, which is characterized in that it mainly ...
