The invention discloses a UASB reactor with pulsed water distribution. The UASB reactor comprises a reaction pond, and a gas-liquid mixing water distributor arranged in the reaction pond, wherein a nitrogen pipe and a water inlet pipe are connected on the gas-liquid mixing water distributor; the water inlet pipe is connected with an adjusting pond through a water pump; an electromagnetic valve isarranged on the nitrogen pipe; a return water pipeline is arranged in the reaction pond, and is communicated with a water inlet pipe and connected on the water inlet pipe between the water pump and the adjusting pond. In the UASB reactor, the gas-liquid mixing water distributor is added into the reaction pond, liquid in the reaction pond is impacted through the water distributor, and the service range can be enlarged after nitrogen is introduced into the water distributor; and nitrogen is introduced into the water distributor, the sprayed water flow has higher impact strength due to the gas effect after gas and liquid are mixed, and the reaction in the reaction pond can be more quickly.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a UASB reactor with pulsed water distribution. Background technique [0002] In the anaerobic or anoxic reaction stage in the field of sewage treatment, UASB reactors are often used. In the UASB reactor, the wastewater is introduced into the bottom of the reactor as uniformly as possible, and the sewage passes upwards through the sludge containing granular sludge or flocculent sludge. sludge bed. Anaerobic reactions occur when wastewater and sludge particles come into contact. The biogas (mainly methane and carbon dioxide) produced under anaerobic conditions causes internal circulation, which is beneficial for the formation and maintenance of granular sludge. Some of the gas formed in the sludge layer is attached to the sludge particles, and the attached and unattached gases rise to the top of the reactor. The sludge rising to the surface hits the bottom of the gas em...
