Description
Technical field
This utility model relates to technical field of sewage, particularly relates to a kind of dispersant type domestic wastewater processing system.
Background technology
Through effort for many years, the sanitary sewage disposal rate of China urban area is greatly improved, and sewage collecting and the treatment facility in city are the most perfect.And the sewage disposal of the vast rural area that economy falls behind relatively does not the most come into one's own, in addition to some important water conservation district has simple sewage-treatment plant, the domestic sewage of villages and small towns of the overwhelming majority is in the state of directly discharge.Rural sewage treatment efficiency is the lowest, lacks supporting sewage disposal device.Owing to domestic sewage of villages and small towns has the features such as displacement is small and scattered, variation water quality is bigger, the character of domestic sewage of villages and small towns and city domestic sewage have relatively big difference, additionally, the process of city sewage plant and operation cost are higher, are not suitable for villages and small towns and use.Because the difference in the conditions such as sewage character, society, economic and technical, municipal sewage technique should not be used at domestic sewage of villages and small towns, and some are if the environmental techniques that process such as artificial swamp are often because of limiting factors such as land resources, it is impossible to meet and process requirement.
At present, for villages and small towns sewage (every day 10m3-2000m3Displacement) separated practices, main employing three major types technology and technique.
The first kind is to use for reference the successful experience of municipal sewage plant's secondary biochemical treatment, the municipal sewage plant secondary biochemical treatment technique miniaturization traditional by some, is applied to villages and small towns decentralized type sewage and processes.Such as SBR, oxidation ditch, A/O, even A2/ O, even MBR etc., these technology and technique are the most more complicated, and the equipment of needs also compares many.Therefore, invest relatively large, system maintenance management is complex, energy consumption and operational and administrative expenses high, and also may produce some secondary pollution problems.
Equations of The Second Kind is to use some relatively simple ecological sewage treatment technology, including artificial swamp, oxidation pond, land treatment system etc..The advantage of this kind of technology is that technique is simple, it is little to invest, low energy consumption, easy maintenance, environmental friendliness etc., shortcoming is that treatment effeciency is relatively low, generally could obtain under certain conditions stable treatment effect and maintain system the most properly functioning, such as relatively low hydraulic load and organic loading and longer hydraulic detention time, this just requires bigger utilizable place, mismanagement is easily caused system jams, affects treatment effect.
3rd class is Anaerobic Methods in Treating, compared with traditional aerobe technology Anaerobic Microbiological Treatment Technology have that technique is simple, energy consumption is low, sludge output is little, nutritional need is few, to advantages such as the wide accommodations at water source, thus anaerobic technology receives and payes attention to widely.But owing to anaerobic technology is affected greatly by temperature, and there is a large amount of by-product-biogas residue, process and be not good at being easily caused secondary pollution, additionally, after only processing with anaerobic technique, sewage is difficult to reach reuse standard.
It is big all to there is sludge quantity in the dispersant type domestic wastewater process technique that treatment effect is stable at present, the problem causing secondary pollution, and the processing cost of mud is higher, make current dispersant type domestic wastewater process technique and be difficult to popularization and application, develop a kind of effectively can not only process sewage and also the dispersant type domestic wastewater of low sludge volume even zero sludge volume process technique have very important significance, it is possible to villages and small towns popularization and application at home.
