A kind of environmental protection equipment using dynamic membrane method

Abstract

The invention discloses an environmental protection equipment using a dynamic membrane method. The equipment includes a pretreatment pool, a mixed liquid pool, a dynamic membrane pool and a sedimentation pool connected in sequence. An additive throwing robot is arranged near the mixed liquid pool. The additive throwing The robot is used to inject dynamic film forming agent into the mixed liquid tank; the outlet of the pretreatment tank is provided with a sewage circulation switch, and the sewage circulation switch is controlled by the general controller. The invention uniquely designs a data processing algorithm for accurately evaluating the pH value and turbidity value of water, and a control algorithm for each switch and regulating valve. Through the above ingenious design, the environmental protection equipment in this application has the following advantages: a high degree of automation, which can realize fully automatic treatment; strong robustness, which can shield various factors that may cause evaluation errors, so that the pH value of sewage and The evaluation result of the turbidity value is sufficiently accurate, therefore, the control precision is high.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to an environmental protection equipment using a dynamic membrane method. Background technique [0002] Sewage treatment (wastewater treatment): The process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical and other fields. Different fields have different sewage treatment methods, and the specific use methods of physical methods and biochemical methods are also quite different. [0003] In the process of sewage treatment, the biofilm method has sprung up in recent years, but the biofilm method also has certain problems, such as the formation of biofilm is difficult to control, and the performance of biofilm is not stable enough. It is difficult to automate the processing, and it is also difficult to achieve...
