High-efficiency environmental-friendly sewage treatment system

Abstract

The invention discloses a high-efficiency environmental-friendly sewage treatment system. The system comprises a main control device, a sewage collecting pool, a water suction pump and a sewage treatment device, wherein the water inlet end of the water suction pump is arranged at the sewage collecting pool; the sewage treatment device comprises a filter tank and a sewage treater; the water inlet end of the filter tank is connected with the water suction pump; a water seepage plate is arranged in the sewage treater; the sewage treater is separated into an upper-layer cavity and a lower-layer cavity by the water seepage plate; a water outlet pipeline is connected to the top of the upper-layer cavity; the lower-layer cavity is connected with the filter tank. The system disclosed by the invention has the advantages that multistage decontamination treatment is carried out on the discharged sewage, so that the system is good in decontamination effect; a traditional decontamination pool structure is improved to ensure that impurity sediments flow back to the sewage collecting pool through a backflow pipeline and is subjected to subsequent cyclic ceaseless decontamination; the work of the water suction pump and the on-off of magnetic valves are controlled by adopting an automatic control way with no need for supervision in the whole process, so that the system is high in decontamination efficiency and friendly to environment in a real sense and can be effectively popularized.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to an efficient and environment-friendly sewage treatment system. Background technique [0002] The traditional sewage treatment system generally only has a primary sewage treatment pool and a secondary sewage treatment pool connected to it, and in the traditional sewage treatment pool, the sewage generally flows in and out, and some impurities and sediments will also flow from the pipeline along with the pipeline. The discharge of the drain outlet makes the sewage decontamination incomplete, and the drainage pipe is also easily blocked by impurity deposits, which cannot achieve a good decontamination effect, and cannot effectively decontaminate and achieve the purpose of environmental protection in a true sense. [0003] Especially for mining operations, the sewage produced is relatively turbid, and there are many impurities and sediments. In the prior art, there...

[0002] The traditional sewage treatment system generally only has a primary sewage treatment pool and a secondary sewage treatment pool connected to it, and in the traditional sewage treatment pool, the sewage generally flows in and out, and some impurities and sediments will also flow from the pipeline along with the pipeline. The discharge of the drain outlet makes the sewage decontamination incomplete, and the drainage pipe is also easily blocked by impurities and sediments, which cannot achieve a good decontamination effect, and cannot effectively decontaminate and achieve the purpose of environmental protection in a true sense

[0003] Especially for mining operations, the sewage produced is relatively turbid, and there are many impurities and sediments. In the prior art, there is no good decontamination system to effectively treat mine sewage. Based on this, we have designed a A set of sewage treatment system with strong practicability, simple operation, convenient and fast, efficient decontamination and environmental protection is very necessary and must have good market promotion value and application value
