Description

The installation method and advanced treatment method for sewage water of integrated sewage water advanced treatment apparatus
Technical field
The present invention relates to technical field of sewage.
Background technology
With the fast development of China's economic, the discharge capacity of sanitary sewage is continuously increased, unprocessed or deal with improperly Sanitary sewage turns into the one of the main reasons of rivers and lakes water quality deterioration.And the weight handled with China city domestic sewage Depending on the Sewage Pollution problem of samll cities and towns and rural area becomes more prominent.Samll cities and towns and country sewage have discharge capacity The features such as small, fluctuation is greatly, biodegradability is good, therefore many foreign uses decentralized processing pattern.Europe and the U.S. has 20%~ 30% population uses decentralized wastewater treatment facility, and the population that Japan has 31% handles sanitary sewage using purification tank, disperses place Reason is also an important measure for promoting samll cities and towns and the development of rural area public health service.
The existing major technique suitable for decentralized wastewater treatment is divided into primary treatment technique and main body handling process.Its In, primary treatment technique includes septic tank, preliminary sedimentation tank etc., is mainly used in part and removes SS;Main body handling process include aeration tank, Biofilter, sbr reactor device, stabilization pond, artificial swamp etc., are mainly used in removing COD, SS, or nitrogen, phosphorus.
On the whole, integral system is convenient than separate type system building, and come into operation fast, instant effect, saves and takes up an area Area.Anaerobic technology is due to the processing water outlet water that anaerobic technology is used alone under certain condition than aerobic technical energy saving Matter does not reach the secondary discharge standard of national regulation, so seldom referring to.The relatively artificial system cost of natural system is low, operation pipe Reason is convenient, and energy consumption is low, but the limitation of climate condition and land area, and effluent quality is not so good as manual system.In nature In system, soil system is good than water body system removal effect, highly reliable.In manual system, MBR goes out than traditional handicraft Water water quality is good, the renewable reuse of sewage, and floor space is small but operational and administrative expenses is high.
In traditional handicraft, apposition growth biosystem (such as biomembrance process and BAF) with activated sludge Method, oxidation ditch and SBR compare for the suspended growth biological systems of representative, and sludge yield is small, and system architecture is simple, but with going out The proposition of the raising of water quality standard, particularly one-level A standards, the existing many traditional handicrafts for being subsequently need to continue additional depth Processing unit.
A kind of trend that integrated sewage water advanced treatment apparatus is this year to develop, is suitable for being not suitable for building sewage disposal Factory or sewage are not easy to be collected into the occasion that sewage treatment plant focuses on, such as small community, scenic spot, tourist attractions With spot camping, hotel, school, Expressway Service etc. are various is limited by geographical position or cost of investment problem is not suitable for receiving Pipe is collected into the occasion of center sewage plant processing.It has low energy consumption, anti impulsion load, reduced investment, operation simple and stable, management Conveniently, the advantages of effect is good.
Integrated sewage water advanced treatment apparatus and method applicability are strong, have a wide range of application;Realize standardized designs, flowing water Line is produced;Operational administrative is simple, dependable performance;The project implementation cycle is short, lands and realizes emission reduction;With many, fast, good, province Feature.The universalness of this device is applied the important means as sanitary sewage disposal and reuse.

The clear water of sedimentation basin 3 enters fiber filter cloth filtering ponds 4 by outlet pipe 3-8 and carries out depth-type filtration processing, fiber filter cloth Vertical provided with filtering rotating cylinder 5-3 in the inner chamber of filtering ponds 4, filtering rotating cylinder 5-3 is on hollow cylindrical, cylinder filtering cylinder sidewall Water hole is opened up, rotating cylinder outer wrapping fiber filter cloth 5-4 is filtered, filtering cylinder bottom sets out the mouth of a river and is connected with clear water reserviors.Filtering turns Cylinder is also connected with drive device 5-1 by drive shaft 5-2, drives filtering rotating cylinder 5-3 to rotate by drive device 5-1.
Filtering rotating cylinder 5-3 is the collection rotating drum that horizontal punching metallic plate is made, and assembles fitted with fiber filter cloth 5-4 anti- Wash suction inlet 5-5 to remove the bulky grain suspension that fiber filter cloth is captured, so as to reach the effect of filtering.While backwash, driving Device drives filtering drum rotation, reaches the effect of 360 ° of filtering rotating cylinder backwashes.
The fiber filter cloth 5-4 wrapped up on filtering rotating cylinder 5-3 is woven into base fabric by bundle fiber doubling to be made, and pencil is fine Dimension is made into by the fiber of nylon and acrylic fibers blending, and the major advantage of bundle fiber is on the top layer of filtration condition fiber filter cloth Compacted fibers layer is formed, fine and close surface filtering layer can intercept the various solid suspensions in medium outside, together When fiber roots space can make again filtered fluid through gap pass through fiber filter cloth and enter filter chamber in discharge, can significantly subtract The drag losses of few fiber filter cloth, and can improve the fineness of filtration system;Fiber filter cloth 5-4 can be according to different works The bundle fiber of condition different with water outlet requirement selection beam diameter and different length.
Fiber filter cloth filtering ponds are different from conventional filter-cloth filtering system, and the filtering rotating cylinder is not to be horizontally arranged at an opening Container in, but be vertically arranged to closing filtering ponds pond body in.
Fiber filter cloth filtering ponds liquid to be filtered from outside to inside, passes through this process, suspended solid quilt by filter cloth It is retained on filter cloth.Filtrate is then from the internal flow of rotating cylinder to outlet.With the increase of suspended solid, on fiber filter cloth, Through the increase of fiber filter cloth flowed friction, so that the pressure in filtering ponds pond body also increases.(once water can not enter liquid level in time Enter to filter rotating cylinder so that liquid level increases pressure increase in pond body) reach default high-value (correspondence high pressure values), cleaning filter Cycle will start.Start the fiber filter back suction pump in sludge-tank, backwash valve (in the pipeline for being located at connection backwash suction inlet) is beaten Open, slowly rotated while filtering rotating cylinder.During backwash, filtrate is forced to lead to is crossing to outside, fiber filter cloth inside fiber filter cloth Cleaned.Filter rotating cylinder external pressure to reduce, the near default low liquid level (correspondence low pressure values) of liquid level in pond body, backwash stops Only, filtering rotating cylinder stops operating.
Fiber filter cloth filtering ponds set most suspended substances in bottom sludge hopper, filter process and are settled down to collection under gravity Bucket, is back in sludge-tank through discharge pipeline.
Fiber filter cloth filtering ponds separately match somebody with somebody automatic control cabinet on machine, pass through the liquid-level switch in filtering ponds pond body (liquid level gauge) realizes regular backwash.
In the use of the present invention, sterilization take chlorine system disinfectant (chlorine dioxide or sodium hypochlorite) can with destroying microorganisms, Directly added to clear water reserviors bottom, and clear water and be sufficiently mixed by chlorination pipe, realize the effect of sterilization, the clear water after sterilization is reachable Arrive《Urban wastewater treatment firm pollutant emission standard》(GB18918-2002) one-level A standards in, water outlet reaches the base of recycle-water This requirement.
