Sewage treatment equipment and anoxic tank carbon adding device thereof

The utility model discloses sewage treatment equipment and an anoxic tank carbon adding device thereof. The anoxic tank carbon adding device comprises a carbon storage tank for storing a liquid carbonsource; the circulating water pump is used for providing sewage; and the mixed jet mechanism is connected with the carbon storage tank through a first material conveying pipe, is connected with the circulating water pump through a second material conveying pipe and is used for mixing a liquid carbon source with sewage. According to the carbon adding device for the anoxic tank, carbon sources canbe more uniformly distributed in sewage in the anoxic tank, so that denitrification reaction in the anoxic tank is more sufficient, and the problem of poor denitrification effect of the anoxic tank issolved. 本实用新型公开了一种污水处理设备及其缺氧池加碳装置，缺氧池加碳装置包括：用以储装液体碳源的储碳罐；用以提供污水的循环水泵；通过第一输料管与所述储碳罐相连并通过第二输料管与所述循环水泵相连、用以供液体碳源与污水混合的混合射流机构。上述缺氧池加碳装置，能够使碳源更均匀地分布在缺氧池内的污水中，使缺氧池内的反硝化反应更加充分，解决了缺氧池脱氮效果差的问题。
