Problems solved by technology
[0004] In the field of environmental protection, there are various sewage treatment technologies, but for the removal of organic matter and nitrogen and ammonia, the traditional methods include SBR, A / O, A 2 / O and other treatment processes, but the efficiency of these treatment processes is not high, the operating cost is high, and it takes a long time to debug, and for some wastewater with high nitrogen and ammonia loads, the treatment effect is not good.

The invention discloses a sequencing batch exchange cycle treatment method for wastewater in activated sludge. The sequencing batch exchange cycle treatment method is applied to the field of wastewater treatment. A reaction tank is divided into an anoxic regulation zone and an aerobic degradation zone by a partition wall, so that nitrification reaction and denitrification reaction can be performedin the same tank body; during operation, by wastewater injection, aerobic aeration and anoxic aeration, continuous cycle exchange of the wastewater, suspended filler and microbial communities betweenthe anoxic regulation zone and the aerobic degradation zone is realized, and the microbial communities are diversified and have higher adaptability, so that the treatment efficiency of the wastewatercan be greatly improved, the treatment effect on ammonia and nitrogen is intensified, the operation of the wastewater treatment process is simplified, and the operation cost is reduced; in addition,normal debugging time of the wastewater in the activated sludge is shortened.
Description
technical field [0001] The invention is used in the field of waste water treatment, and in particular relates to a method for treating waste water of sequenced batch exchange circulation activated sludge. Background technique [0002] my country is a country with severe drought and water shortage. The total amount of fresh water resources is 2.8 trillion cubic meters, accounting for 6% of global water resources, ranking fourth in the world after Brazil, Russia and Canada, but the per capita is only 2300 cubic meters. It is only 1 / 4 of the world average and 1 / 5 of the United States. It ranks 121st in the world and is one of the 13 countries with the poorest per capita water resources in the world. [0003] According to monitoring, groundwater in most cities across the country is currently subject to point and surface pollution to a certain extent, and there is a trend of increasing year by year. The increasingly serious water sludge not only reduces the use function of water ...
