Problems solved by technology

[0024] However, this GB 3544-2008 standard also violates the original intention of promulgating this standard to take the road of green and sustainable development. The problem lies in: the index value of pollutants in water produced by pulp and / or papermaking production Both are far higher than the specified value of GB3544-2008. In order to make the limited quality and limited discharge water meet the standard, the enterprise must repeatedly purify and reuse the water. In this process, it will not only increase the processing cost of the enterprise , consumes a lot of energy, and will cause the content of water-soluble inorganic salts such as NaCl and / or Na2SO4 in the water to rise rapidly, reaching a value far higher than the 2-3‰ value that vegetation can tolerate, making the water unable to be It can be directly used for farmland irrigation and cannot be recycled by the production process
[0029] To sum up, in the field of plant fiber product production, there is no perfect and universally applicable method to set up horizontal and vertical mass transfer channels in the product production field internally and externally, and to implement collaborative clean co-production in the field of multi-industry product production. Plan; according to the modern concept of sustainable development, the comprehensive evaluation of the full amount, green, efficient, energy-saving and recycling of resources is carried out. The existing process routes in various fields, although there are prevailing chains with their own advantages, However, each encounters its own technological barriers or nodes that are difficult to overcome independently; the industry has not yet mentioned the requirement to reduce sodium ions in water to a safe range of ≤1‰ that vegetation can withstand.

Embodiment 1

[0110] Such as figure 1 A schematic block diagram of a clean production method for plant fiber products is provided, and the clean production method is specifically described as follows:

[0111] First of all, this embodiment conforms to the technical concept proposed by the present invention, namely:

[0112] A: The horizontal space between cotton or / and hemp and its yarn, fabric degreasing, bleaching sub-product production field a-1 and pulp and paper sub-product production field a-2 in plant fiber product production field a, and In the longitudinal space between the upstream and downstream processing processes in each of said a-1 and a-2, or / and the horizontal space between the production processes of different lower-level products in a-2, or a-1 or / and the horizontal space between a-2 and compound fertilizer nutrient soil product field b or feed product field c, or / and a-1 or / and a-2 and soil ceramic brick product field d, cement product field e , water-based cleaning l...

example 1-11）

[0151] (Example 1-11). The productive external drainage of combined treatment device Ⅰ or / and Ⅱ carried by a, such as figure 1 Described in middle box 13, 28, it is supplied to the production field of b product, and it is used as liquid compound fertilizer. It is characterized in that: the degreasing process is adjusted according to the ratio of soluble inorganic nutrients in water according to the compound fertilizer formula or the farmland needs. The most concentrated or second-concentrated color-containing external drainage discharged from the first or second solid-liquid separation makes the water discharged from the combined treatment device I or / and II carried by a become a liquid compound fertilizer with beneficial properties; The method of applying liquid compound fertilizer is to send it to the field by tanker or / and pipeline or / and ditches, and control the concentration of total soluble inorganic salts (weight) in water to be less than 2‰ by diluting with water, and t...

Embodiment 2

[0175] Such as figure 2 Said is another schematic block diagram of a clean production method of a plant fiber product according to the present invention.

[0176] according to figure 2 Described, in the present embodiment, what specifically introduced is with cotton or / and linen and its yarn, fabric any one, or waste paper, cotton stalk, straw, wheat straw, reed, mulberry branch, poplar, Eucalyptus, bamboo willow, bagasse, and cow dung are used as raw materials to produce degreased bleached cotton or / and hemp and its yarn, fabric, or with non-bleached pulp or bleached pulp, and compound fertilizer Products, clean co-production of waste incineration products.

[0177] according to figure 2 Said, the degreasing or bleaching combination device I carried by cotton or / and hemp and its yarn, fabric degreasing or bleaching sub-product production field a-1 in the plant fiber product production field a, which at least includes: 3 is a tap water valve, 4 is a water storage tank f...

Abstract

The invention discloses a clean production method of a plant fiber product, relating to the regeneration treatment on the black liquid generated by the deinking or degreasing or / and delignification in a production process of the plant fiber product or / and the implementation of interception-type recycling of the black liquid containing sodium ions, relating to the circulating water treatment and application in a production process in the field of different sub-products of the field of plant fiber products, relating to the treatment and utilization of the sludge obtained in black liquid regeneration and circulating water treatment processes, and relating to the blending treatment and utilization of drain water, wherein the plant fiber at least comprises any one of cotton and fibrilia crops, crop straw including any one of cotton straw, rice straw, wheat straw, reed, corn straw and the like, weed including any one of carex meyeriana, solidago decurrens and the like, broadleaf wood and the like including any one of poplar and eucalyptus, bagasse discarded by the sugar industry and any one of waste paper and old cotton or the combination of more than one waste plant fiber product and the like.

Description

technical field [0001] The invention proposes a clean production method of plant fiber products, which involves the regeneration treatment and recycling of black liquor formed by deinking, degreasing or delignification in the production process, and belongs to plant fiber products or compound fertilizers. The technical category of the coupling or integration of horizontal and vertical process nodes in the field of multi-product production of nutrient soil, feed, etc. Background technique [0002] Between the production field of plant fiber products and the field of production of compound fertilizer nutrient soil or feed, there is no close and unobstructed outward horizontal and vertical mass transfer coupling process channel; in the field of plant fiber product production, cotton or / Between the sub-product production fields of hemp and its yarns and fabrics and the sub-product production fields of pulp and papermaking, there is no process channel for horizontal and vertica...
