The invention discloses a method for 
processing wastewater containing alkaline mud with high COD concentration, high 
toxicity, low biodegradability and high chroma. In the invention, a micro-
electrolysis pretreatment, and flocculating and decoloring process are adopted to reduce the COD concentration and chroma and improve the biodegradability, thus providing 
precondition for the subsequent acidified 
hydrolysis and 
aerobic treatment system to further eliminate alkaline mud 
contamination load; and the yielding water is deposited by a deposition 
pool and discharged after disinfection. In the invention, the COD concentration (80,000-300,000mg / L) and the chroma (12,500-50,000 times) of inflowing water are improved to maximum degree, stability for the running of 
system is considered sufficiently, a large amount of diluted water required in the running process is saved, the yielding water can be directly exhausted to urban 
sewage pipelines, received by waterbody or combined in other treatment systems for treatment, and can comply with the recycling standard. In the whole treatment process, the secondary 
pollution is not generated, the total emission amount of COD is reduced, the whole 
system runs conveniently and quickly, and the investment and running expense is far lower than that of the traditional film 
treatment system.
