Description

A kind of Sewage treatment systems
Technical field
The utility model relates to water treatment field, is specifically related to a kind of Sewage treatment systems.
Background technology
Along with the development of society, the continuous progress of productivity, people have also made increasing research to the problem of the recycling of water resources, and wherein, by sewage source classification, sewage disposal is generally divided into production waste process and sanitary sewage disposal.Production waste comprises industrial sewage, rural sewage and medical sewage etc., and sanitary sewage is exactly the sewage that daily life produces, and refers to various forms of inorganics and organic complex mixture, comprising: the 1. floating size solid particulate with suspending; 2. gluey and gel diffusate; 3. pure solution.Washing composition, agricultural chemicals and municipal wastewater that particularly nitrogen and phosphorus content is high, and high density waste water difficult for biological degradation is as the process of the trade effluents such as coal, electric power, metallurgy, plating, light industry (papermaking, weaving, process hides), extremely urgent, how to process this type of sewage and to recycle is the problem needing now solution badly.
Utility model content
The utility model provides a kind of Sewage treatment systems, has perfect water treatment and the system of recycling, and in order to solve technique scheme, the utility model adopts following technical scheme:
A kind of Sewage treatment systems, comprise sewage treating part up to standard and wastewater reusing treatment part, described sewage treating part up to standard comprises coagulative precipitation tank one, air flotation pool, anaerobic pond, anoxic pond, Aerobic Pond, settling tank, mixed reaction pond and the coagulative precipitation tank two connected successively, described coagulative precipitation tank two is all connected with sludge thickener with settling tank, is connected with whizzer or pressure filter after described sludge thickener; Described wastewater reusing treatment part comprises wastewater reusing treatment unit one and wastewater reusing treatment unit two, wastewater reusing treatment unit one comprise connect successively BAF filter tank, settling pond, activated carbon filtration pond one and membrane treatment appts one, described membrane treatment appts one is micro-filtration or ultrafiltration membrane treatment device; Described wastewater reusing treatment unit two comprises the stirring-type filter tank, fiber bundle filter device, active carbon filtering device two and the membrane treatment appts two that connect successively, and described membrane treatment appts two is micro-filtration or ultrafiltration membrane treatment device; The backwash drain outlet of described stirring-type filter tank, active carbon filtering device two and active carbon filtering device one is connected by pipeline with the entrance of anaerobic pond.
Advantage of the present utility model and beneficial effect are:
The Sewage treatment systems that the utility model provides, comprises sewage treating part up to standard and wastewater reusing treatment part, achieves sewage disposal and recycling, make effluent reuse resource utilization, save resource greatly.
The Sewage treatment systems that the utility model provides, focuses on the mud in coagulative precipitation tank and settling tank, is carried out burning or transporting outward by concentrated mud, decreases step, accelerate working efficiency.
The Sewage treatment systems that the utility model provides, sewage treating part up to standard comprises multiple process unit, multifeed clarifier, simultaneously before sewage enters mixed reaction pond, adds PAC, improves the process of sewage further.
The Sewage treatment systems that the utility model provides, is combined the backwash drain outlet in wastewater reusing treatment unit one and unit two by pipeline, carries out again the process of A2/O before again getting back to anaerobic pond simultaneously, ensures the quality of draining.
The Sewage treatment systems that the utility model provides, the clearance that the clearance that the clearance of COD, BOD, SS reaches 90% ~ 95%, P reaches 90%, N reaches 70%.
The Sewage treatment systems that the utility model provides, utilizes internal recycle to provide anti-nitration reaction object, and denitrification can produce alkali simultaneously, saves caustic dosage, decreases cost.
Accompanying drawing explanation
