Intensive garden type sewage treatment system and treatment process

Abstract

The invention relates to the technical field of sewage treatment, in particular to an intensive garden type sewage treatment system and a process thereof. The system comprises a water treatment tank area and an equipment room, due to the fact that construction of subunit structures in a water treatment system is not concentrated, civil engineering operation is scattered, and due to the high-standard civil engineering requirement, the operation cost is high, and the field management difficulty is large; therefore, by arranging a quasi-circular combined pool, the water treatment tank area in the sewage treatment system is combined with the site of the equipment room, so that the intensification formed by the water treatment system is beneficial to the future operation and maintenance, and a green belt is constructed in the area outside the combined pool, an effluent of the water treatment system can be directly used for greening irrigation, the water treatment system forms a garden-type layout, the operation requirement of the system is met, the function division is clear, the water treatment system is more harmonious and attractive with the surrounding environment, and therefore the intensive garden-type function of the water treatment system is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an intensive garden-style sewage treatment system and a treatment process. Background technique [0002] Farm sewage mainly includes urine, some feces and flushing water, which is a high-concentration organic sewage with high concentrations of COD and ammonia nitrogen. The current aquaculture wastewater treatment technology is mainly based on water quality characteristics, first remove suspended solids and chroma, adopt coagulation sedimentation process, and use biochemical treatment for organic matter, ammonia nitrogen, and organic phosphorus. Due to the high concentration of pollutants, considering the cost and treatment effect , using anaerobic and aerobic treatment processes. [0003] At present, the aquaculture wastewater treatment process is mainly divided into several independent sections: thus, there are the following obvious disadvantages: ① The land for the st...

[0003] At present, the aquaculture wastewater treatment process is mainly divided into several independent sections: thus, there are the following obvious disadvantages: ① The land for the structures is not concentrated, the civil work is scattered, the operation cost is high, and the on-site management is difficult

②The pipelines between the various sewage treatment systems in the plant area are chaotic and poor in aesthetics; ③The sewage treatment system still needs to be equipped with labor in the plant area, and no one is on duty yet; ④The traditional technology has a lot of biochemical sludge discharged outside, and there is secondary pollution

[0005] For example, a Chinese patent with application number CN201310255710.4 discloses a highly active biological bed sewage treatment intensive system and sewage treatment method. The sewage treatment intensive system includes grid wells connected in series, preliminary sedimentation tanks, sewage Mud acidification tank, multi-stage desilting tank aerobic tank unit, MBR membrane bioreaction tank, disinfection tank; each desilting tank is equipped with filler, and the lower part of each aerobic tank is equipped with an aerator unit. The MBR The lower part of the membrane bioreactor tank is provided with an aerator unit, and each aerator unit is connected to a blower through a pipeline; the MBR membrane bioreactor tank is equipped with an MBR membrane module; this technical solution will not cause the activated sludge process. In addition, the sewage is repeatedly scrubbed through the anaerobic HSB bacteria release / aerobic process to change the growth environment of microorganisms, thereby screening, enriching, and fixing dominant bacteria. It forms a highly active biological bed to treat sewage efficiently; however, the intensive sewage treatment system in this technical solution only connects the various functional pools in series, so that the advantages of its intensive degree are not obvious enough and cannot be fully utilized. The advantages of constructing an intensive sewage treatment system
