Embodiment 1

[0023] Example 1 Domestic sewage biological integrated treatment equipment

[0024] Such as figure 1 As shown, the domestic sewage biological integrated treatment equipment includes a main container 8, a sewage inlet conduit 4, an aerator 5 and a sludge discharge conduit 6, wherein:

[0025] The inside of the main container 8 is provided with a first aeration reaction chamber 1 and a second aeration reaction chamber 2 surrounding the first aeration reaction chamber 1, wherein the first aeration reaction chamber 1 and the second aeration reaction chamber 2 The lower bottom surface of the main body container 8 overlaps with at least a part of the lower bottom surface of the main body container 8 respectively, while the side surfaces and upper bottom surfaces of the first aeration reaction chamber 1 and the second aeration reaction chamber 2 are not in contact with each surface of the main body container 8, thus the main body The space inside the container 8 that is not the firs...

Embodiment 2

[0032] Application effect of embodiment 2 domestic sewage biological integrated treatment equipment

[0033] Use the equipment described in the embodiment of the present invention 1 to carry out sewage treatment, its result is as follows figure 2 As shown, when the hydraulic retention time (HRT) is 8 hours, the average influent COD is 274.2mg / L, the average effluent COD is 26.1mg / L, and the average COD removal rate is 92.3%; the average influent ammonia nitrogen is 40.2mg / L L, the average ammonia nitrogen in the effluent is 12mg / L, and the average removal rate of ammonia nitrogen is 71.7%; while the average nitrate in the effluent is 11mg / L, it can be seen that the degree of ammonia nitrogen oxidation by aeration is quite high; in addition, the average alkalinity of the influent is 340.3mg / L, the average effluent alkalinity is 102.2mg / L, and the reaction consumes 70.0% of the raw water alkalinity. It can be seen that the equipment of the present invention can perform effici...

Abstract

The invention relates to a biological integrated treatment device of domestic sewage, comprising a main body container, a sewage intake conduit, an aeration machine and a mud drainage conduit. The inner space of the main body container of the device is fully utilized and separated into two aeration reaction chambers as well as a clarifying chamber, and sewage is led in along the flowing directionof a stream and sequentially treated through the aeration reaction chamber and the clarifying chamber. In addition, the invention also preferably fills the aeration reaction chamber of the equipment with a biological cube vector for improving the biodegradation efficiency of the aeration reaction chamber.

Description

technical field [0001] The invention belongs to the field of sewage treatment. Specifically, the invention relates to a biological integrated treatment equipment for domestic sewage. The equipment has a high degree of structural integration and reasonable space utilization. In addition, it is filled with an optimized cubic microbial carrier and can efficiently treat domestic sewage. Background technique [0002] With the process of urbanization and the increase of population density, the treatment of domestic sewage has attracted more and more attention. In particular, our country is a country with a shortage of water resources. The per capita water resource is only a quarter of the world average (approximately 2200m 3 ). In 2006, the Chinese government issued the "National Medium- and Long-Term Science and Technology Development Plan", which proposed that on the premise of adhering to the priority of energy conservation and reducing energy consumption, we should focus on ...
