Description

Technical Field

[0001] The utility model belongs to the technical field of sludge pools, and in particular relates to a sludge pool of a sewage plant which is easy to clean. Background Art

[0002] During the sewage treatment process, a large amount of sludge will adhere to the wall of the sludge pool, and this sludge needs to be cleaned frequently. After a series of sludge treatments, the existing sludge pool still has a large amount of difficult-to-clean sludge at the bottom of the sludge pool. If it is not cleaned in time, the sludge will accumulate at the bottom of the sludge pool. Since the sludge pool is deep and the dried sludge is heavy, taking out the sludge will increase the difficulty of sludge treatment. Moreover, when it is necessary to add sewage treatment agent into the sludge pool, the sewage treatment agent is generally poured directly from a certain point above the sludge pool, resulting in more sewage treatment agent accumulation in this part. On the one hand, it leads to uneven contact between the sewage and these sewage treatment agents, resulting in uneven purification treatment effects. On the other hand, in order to make the sewage treatment agent and the sewage mix evenly, it takes a lot of time to stir, which will reduce the efficiency of sewage treatment and have poor sewage treatment effect.
