Description
技术领域 technical field
本实用新型涉及一种新型水力搅拌循环罐。 The utility model relates to a novel hydraulic stirring circulation tank. the
背景技术 Background technique
目前，高浓度有机废水与消化液混合处理一般是利用调节池，将消化液循环到调节池，在调节池内与一次废液混合调节PH值后，再用提升泵泵入厌氧罐，进行厌氧消化处理，但利用调节池进行混合时存在的问题是：第一、调节池大都是采用砖混建造而成的露天水泥池，所以产生的刺激性气体容易扩散到周围环境中，影响周围居民的居住环境，污染了大气；第二、在混合过程中产生大量沼气，无法收集利用，造成资源浪费；第三、由于厌氧罐比较高，在将混合液从调节池泵入厌氧罐过程中对提升泵的扬程要求高，动力消耗大，造成能源浪费。 At present, the mixed treatment of high-concentration organic wastewater and digestive juice generally uses the adjustment tank to circulate the digestive juice to the adjustment tank. After mixing with the primary waste liquid in the adjustment tank to adjust the pH value, it is pumped into the anaerobic tank with a lift pump for anaerobic treatment. Oxygen digestion treatment, but there are problems when using the adjustment tank for mixing: First, most of the adjustment tanks are open-air cement pools made of brick and concrete, so the irritating gas generated is easy to diffuse into the surrounding environment and affect the surrounding residents. Second, a large amount of biogas is generated during the mixing process, which cannot be collected and utilized, resulting in a waste of resources; third, due to the relatively high anaerobic tank, the mixture is pumped from the adjustment tank into the anaerobic tank. The head of the lift pump is required to be high, and the power consumption is large, resulting in energy waste. the
