Problems solved by technology

Integrate the cultivation and acclimatization of the salt-suitable bacteria agent and the start-up of the MBBR process to realize the rapid start-up and operation of the reactor directly under specific high-salt conditions, suitable for high-salt, high-concentration, toxic, refractory high-salt wastewater The treatment overcomes the problems of the current high-salt biofilm treatment system, such as long salinity acclimation start-up period, insufficient salt tolerance, difficulty in film formation of fillers, poor system operation stability, and low treatment efficiency, which seriously restrict engineering applications.

Abstract

The invention relates to an integrated high-salt wastewater MBBR (moving bed biofilm reactor) treatment device which comprises an MBBR aeration tank with a suspended filler and a microbe culture device connected with the MBBR aeration tank, wherein the microbe culture device is arranged inside or outside the MBBR aeration tank; the MBBR aeration tank is used for treating high-salt wastewater, and part of the treated wastewater enters the microbe culture device for halophile flora culture; and the halophile flora cultured by the microbe culture device is used for degrading organic matters in the MBBR aeration tank and subjected to biofilm formation growth on the suspended filler. The integrated high-salt wastewater MBBR treatment device enhances the high-salt wastewater treatment capacity and treatment effect of the MBBR process, and is especially suitable for treating high-salt high-concentration toxic nondegradable high-salt wastewater.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment and environmental protection, and relates to a high-salt wastewater treatment device, in particular to an integrated high-salt wastewater MBBR treatment device. Background technique [0002] High-salt wastewater refers to wastewater with a total salt content of at least 1%, which is widely produced in many industrial practices such as chemical industry, pharmaceuticals, leather, food, oil extraction, seafood processing, and seawater substitution. As high as 15~30%. In addition, wastewater also contains a large amount of toxic, harmful and refractory organic matter. General physical and chemical treatment requires high energy consumption costs and is prone to secondary pollution. Therefore, biochemical treatment technology is still the first choice. [0003] Based on the serious impact of high salt concentration on the growth characteristics of microorganisms, the difficulty of biologi...
