Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment devices, in particular to an integrated hydrolysis and acidification wastewater treatment device. Background Art

[0002] The amount of wastewater generated is increasing year by year. How to treat this wastewater efficiently and environmentally friendly has become a common challenge. Traditional wastewater treatment methods, such as physical, chemical and biological methods, although they have played a role in purifying water quality to a certain extent, often have problems such as low treatment efficiency, high energy consumption, and secondary pollution. The integrated hydrolysis and acidification wastewater treatment device came into being. This device combines two important biological treatment processes, hydrolysis and acidification, and aims to improve the biodegradability of wastewater by optimizing biological treatment conditions, thereby improving the efficiency and effectiveness of wastewater treatment.

[0003] The hydrolysis process breaks down complex organic matter in wastewater into simpler organic compounds. This step increases the biodegradability of the wastewater and creates favorable conditions for subsequent biological treatment. The acidification process, based on hydrolysis, further converts organic matter in the wastewater into inorganic matter, reducing the wastewater's COD (chemical oxygen demand) and BOD (biological oxygen demand), thereby alleviating the burden on subsequent treatment processes.

[0004] The current wastewater treatment system generally adopts the method of hydrolysis and acidification followed by contact oxidation when treating difficult-to-degrade and high-ammonia nitrogen wastewater. However, during the hydrolysis and acidification process of the wastewater, it contains a lot of sediment and other pollutants, which will affect the hydrolysis and acidification of the wastewater and reduce the working efficiency of the hydrolysis and acidification.
