Embodiment 1

[0031] Such as figure 1 Shown, ramie sewage treatment process is characterized in that, comprises the following processing steps:

[0032] A. Black liquor pretreatment;

[0033] B. Black liquor sludge treatment;

[0034] C. Pretreatment of hemp wastewater;

[0035] D. Comprehensive wastewater treatment;

[0036] E. Biochemical sludge treatment.

[0037] The black liquor in step A is biological degumming wastewater. The black liquor first enters the black liquor regulating tank for homogenization and equalization, and then enters the spray room for treatment. Then the supernatant enters the black liquor hydrolysis acidification pond and the black liquor multi-stage anaerobic pond. Under the action of anaerobic bacteria, the difficult-to-handle macromolecular substances are biohydrolyzed into easy-to-handle low-molecular substances At the same time, the long-chain organic matter in the wastewater is converted into small molecular organic matter, so that the dissolved organi...

Abstract

The invention discloses a ramie sewage treatment process which comprises the following process steps: A, pre-treating black liquid; B, treating black liquid sludge; C, pre-treating scotching wastewater; D, comprehensively treating wastewater; and E, treating biochemical sludge. The invention provides the ramie sewage treatment process, so that the difficult problem of difficulty for treating ramie wastewater is solved, the ramie wastewater is discharged according to the standard after comprehensive treatment, and the total amount of pollutant discharge is reduced; and meanwhile, most of the wastewater is recycled after being treated for reaching the standard, so that the water resources are saved and the sewage treatment and production costs are reduced.

Description

technical field [0001] The invention relates to a sewage treatment process, in particular to a process for treating sewage produced during ramie production. Background technique [0002] Ramie is one of the important textile raw materials in my country. Ramie has a long history of production, and its products are loved by people because of their advantages such as crisp wearing and good air permeability. Ramie degumming is the pre-process of hemp fiber weaving, and chemical degumming is mostly used. At present, most manufacturers in my country still use chemical degumming. The chemical degumming method is to use NaOH to cook the ramie under high temperature and certain pressure to remove the colloidal substance in the ramie fiber. After degumming, the ramie is processed into dry hemp through processes such as kneading, pickling, washing, bleaching and drying. Dry hemp can be used as fiber for spinning and weaving. Ramie can be smelted and washed before it can become a tex...
