Embodiment 3

[0051] The treatment method of high-concentration ammonia nitrogen organic wastewater, such as Figure 1-4 shown, including the following steps:

[0052] A. Anaerobic digestion treatment:

[0053] The high-concentration ammonia nitrogen organic wastewater enters the homogenizer tank 2 through the feeding hopper 1, and is uniformly prepared under the stirring action of the stirring device of the homogenizer tank 2, and then passes into the biogas tank 3;

[0054] The high-concentration ammonia nitrogen organic wastewater is in a mixed state under the action of the stirring device and the reflux spraying system in the biogas tank 3. The sludge generated during the anaerobic digestion process is discharged to the sludge thickening tank 8 through the sludge discharge port, and the sludge is precipitated. After being concentrated, it is pumped away by a sludge pump, and the remaining high-concentration ammonia nitrogen organic wastewater is then passed into the up-flow anaerobic s...

Abstract

The invention relates to the technical field of wastewater treatment and discloses a treatment system of high-concentration ammonia nitrogen organic wastewater. The system comprises a feed hopper (1), a homogenating tank (2), a methane tank (3), an upstream type anaerobic sludge bed reactor (4), a biological contact oxidation pond (5), a secondary sedimentation tank (11), a micro electrolytic reactor (10), a circular aeration biological filter (6) and an ozone disinfection tank (7), and the methane tank is connected with a sludge thickener (8). The invention further discloses a treatment method of the high-concentration ammonia nitrogen organic wastewater. The treatment method comprises anaerobic digestion treatment, activated sludge treatment, micro-electrolysis reaction, circular aeration biological filter biochemical treatment and ozone disinfection. The process is simple, the reaction process concentration gradient is large, and sludge is not prone to bulking; the capability to resist impact load is high, and the treatment effect is good; all working procedure time is controlled by adjusting the operation period, and at the same time, denitrification and phosphorus removal effects are remarkable.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, relates to a treatment system for high-concentration ammonia-nitrogen organic wastewater, and particularly relates to a treatment method for high-concentration ammonia-nitrogen organic wastewater. Background technique [0002] The properties and sources of high-concentration ammonia nitrogen organic wastewater are different, and the treatment technologies are also different. Usually, high-concentration ammonia nitrogen organic wastewater can be divided into three categories according to the nature and source of high-concentration ammonia nitrogen organic wastewater: the first category is high-concentration ammonia nitrogen organic wastewater that does not contain harmful substances and is easily biodegradable, such as food industry wastewater; High-concentration ammonia nitrogen organic wastewater that is easy to biodegrade, such as some chemical industry and pharmaceutical industry wast...
