Description
Technical field
The present invention relates to a kind of high concentrated organic wastewater integrated approach technologies, more particularly to a kind of useless suitable for flax degumming
The modularization integrated technique of water process, the high concentration wastewater treatment generated in process of production for flax spinning industry enterprise are asked
Topic, carries out that technique is integrated and Parametric designing, realizes technical module, intelligence, integrated.
Background technology
Textile industry be Chinese national economy conventional column industry and important people's livelihood industry and China international competing
Industry with the obvious advantage in striving in flourish the market, expands outlet, receives employment, increases farmers' income, promotes Urbanization Progress
Etc. play an important role, but textile industry waste discharge amount is big simultaneously, and concentration of organic wastewater is high, is that China's weight is dirty
Contaminate one of industry.
Chinese bast-fibre textile process industry is broadly divided into ramie textile according to fiber and technology features, flax is spun
It knits.Also contain the non-cellulose components such as hemicellulose, pectin substance, lignin in fiber crops other than containing cellulose, these are non-
Cellulose components are referred to as colloid, and colloidal substance can be obtained spinnability fiber in removal fiber crops, this process is known as degumming.Bast fibre spinning
It is mainly degumming waste water to knit waste water, and non-cellulose components are generally 25%-the 35% of fiber weight in flaxen fiber, therefore degumming is useless
Water pollutant content is higher.
Major pollutants are that lignin and its intermediates, hemicellulose and its degradation are intermediate in flax degumming waste water
Product, tannin, pectin, resin acid etc., flax degumming Wastewater Pollutant leading indicator are shown in Table 1.
1 flax degumming Wastewater Pollutant leading indicator of table
The good Anaerobic treatment technique for the treatment of process generally use aerobic biological treatment process of flax degumming waste water combines
Form, obtained preferable treatment effect, but there is also following problems：
(1) using traditional anaerobic technique, such as when upflow anaerobic sludge blanket process (UASB), due to the SS of flax degumming waste water
It is worth larger, therefore the granule sludge culture of anaerobic device is more difficult, and system start-up time is longer, substantially increases the economy of enterprise
Burden；
(2) traditional activated sludge process is used, such as when SBR techniques, since flax degumming waste water dissolved organic matter contains
Amount is high, F/M high, causes aerobic stage that the high viscosity expansion of sludge occurs, influences sedimentation effect, causes water outlet SS values not up to standard；
(3) traditional biomembrane process is used, such as when contact oxidation technology, since flax degumming waste water SS values occupy height not
Under, cause filler to be easy to block, water distribution, aeration are not easy uniformly, dead angle locally occur, influence treatment effect；
(4) flax degumming waste water can cause waste water index to vary widely because of the difference of degumming tech, even
Using the textile company of same technique, as the constituent of Various Seasonal difference flax raw material is different and leads to waste water
Ingredient is different, and waste water index can vary widely, and processing system is caused to face larger load variations, and effluent index is unstable；
(5) flax degumming wastewater discharge is big, and reuse water demand is big, but at present technology depth, the degree of automation, set
Standby quality etc. is horizontal relatively low, greatly hinders the development of flax textile industry.
