Embodiment Construction
[0053] The present invention will be described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited by the accompanying drawings.
[0054] figure 1 It is the process roadmap of the present invention. As shown in the figure, an online monitoring system is set at the water inlet, and the results are output to the automatic control system through the collection and analysis of the water quality information of the incoming raw water, and the automatic control system sends a module or sub-module The unit sends signals to control the automated operation of the overall process.
[0055] The sewage first enters the first-level pretreatment module, which includes 3 units in total, namely the mobile coarse grid basket, the regulating pool and the air flotation pool, which are operated in series, and the gap between the coarse grill bars is 5-10mm; the designed residence time of the regulating pool is 24h; the de...

Abstract
The invention relates to a modularized integrated process method suitable for the treatment of flax degumming wastewater. The process integration and parameterization design are carried out for high-concentration flax degumming wastewater. The process consists of a first-level pretreatment module, a second-level biochemical module and a third-level advanced treatment module. Composed of 3 modules, the first-level pretreatment module is equipped with mobile coarse grid baskets, regulating pools and air flotation tanks to remove suspended solids and adjust water quality and water quality; the second-level biochemical module is equipped with anaerobic contact reactors, anoxic reactors and aerobic reactions The unit removes the main pollutants in the wastewater. The aerobic reaction unit has two reactors, namely the fixed biofilm-activated sludge reactor and the biological fluidized bed reactor. According to different influent water quality conditions, different reactions are selected and operated. device. The three-level advanced treatment module is equipped with radial flow sedimentation tank and SPR sewage purifier to remove SS and disinfect. The process of the invention has the characteristics of simplicity, flexibility, high efficiency, intelligence and the like, and can ensure economical, effective and stable operation of waste water treatment facilities.
Description
technical field [0001] The invention relates to an integrated treatment technology for high-concentration organic wastewater, in particular to a modular integrated process suitable for the treatment of flax degumming wastewater, aiming at the problem of high-concentration wastewater treatment produced in the production process of flax spinning industrial enterprises, and to carry out process integration And parametric design to realize process modularization, intelligence and integration. Background technique [0002] The textile industry is a traditional pillar industry of our country's national economy and an important livelihood industry. It is also an industry with obvious advantages in our country's international competition. It plays an important role in prospering the market, expanding exports, absorbing employment, increasing farmers' income, and promoting urbanization. However, at the same time, the textile industry discharges a large amount of wastewater and has a h...
