Description
Technical field
The present invention relates to the auxiliary aeration process of municipal sewage plant, a kind of municipal sewage plant is related in particular to
Auxiliary blow-down pipe construction method.
Background technology
It is divided into two kinds of mode of operations in biochemistry pool：One kind is normal operation mode；One kind is backwash mode.
Under normal operation mode, sewage is continuously across the floating stuffing in CFIC reactors and gradually in the hollow part of filler
Form biomembrane and then increase the contact area of microorganism and sewage, the microorganism on biomembrane contacts with municipal wastewater and gives birth to
Change reaction, except the pollutants such as COD, BOD, TP, the TN in decontaminated water are purified sewage.Filler is by the stirring in reaction tank
Device and aerating system mix with sewage.
Under backwash mode, biochemistry pool controls liquid level to raise and be aerated by gate, and biochemistry pool is backwashed,
Bring the long sludge of the sludge age in biochemistry pool into biochemistry pool last flushing pond, sludge is precipitated herein and eventually enters into dirt
Mud carries out sludge dewatering between being dehydrated.The pattern is not required to set second pond on the premise of standard water discharge is ensured, with floor space
The features such as small, operation management convenience, low cost.
For existing normal operation mode, its emptying well is designed as fiberglass perforate cover plate, but the design because of reaction tank
Inside there are a large amount of biologic packing materials and be vented that size is smaller, effective emptying contact area of fibreglass reinforced plastic cover is small, by shadow when being vented
Emptying speed and emptying quality are rung, longtime running, the mud that biologic packing material is produced easily blocks emptying well, and manually cannot be clear
Reason.
The content of the invention
Goal of the invention of the invention is：For above-mentioned problem, there is provided a kind of municipal sewage plant's auxiliary is put
Blank pipe construction method, by improving, increases emptying contact area, so that effectively lifting emptying efficiency and emptying quality.
The technical solution adopted by the present invention is such：
A kind of municipal sewage plant aids in blow-down pipe construction method, comprises the following steps：
（1）Support is set up：Emptying Jing Chu outside biochemistry pool sets up 304 stainless steel stents；
（2）Blow-down pipe is connected：304 stainless steel blow-down pipes are placed on 304 stainless steel stents, and with 304 stainless steel bends by 304
Stainless steel blow-down pipe bottom is connected with the wall pipe for putting in stainless steel aeration tube, is evenly arranged on the 304 stainless steel blow-down pipe
Some 8mm holes, empty rate thoroughly reaches 50%-70%；
（3）Anchor ear is fixed：304 stainless steel blow-down pipes are fixed on 304 stainless steel material supports with 304 stainless steel hoops；
（4）Blow-down pipe is installed：304 stainless steel blow-down pipe upper ends are closed with 304 stainless steel blind plates；
（5）Support angle is adjusted：304 stainless steel stents are adjusted, makes the angle of inclination of 304 stainless steel blow-down pipes in 40-50 degree models
Enclose；
（6）Fixed support：304 stainless steel stents are fixed in measurement for biochemical pool wall with chemical bolt；
（7）Elbow welding is fixed：304 stainless steel bend two ends are fixed with 304 stainless steel blow-down pipes and wall pipe spot welding；
（8）Wrap up blow-down pipe elbow：To wrap up tight at elbow welding with 304 stainless steel mesh sheet；
（9）Backwash tube is installed:The horizontal segment perforate on 304 stainless steel backwash tube tops is simultaneously arranged in biochemistry pool, and 304 are not
The vertical section of rust steel backwash tube is arranged on biochemistry pool outside and is fixed on pool wall using 304 stainless steel hoops, and 304 are not
Rust steel backwash tube lower port reaches downwards 304 stainless steel blow-down pipe bottoms always, and port closed is simultaneously uniformly distributed some 8mm
Hole；
（10）Trial operation aeration experiment：During trial operation, the water level in biochemistry pool is higher than blow-down pipe upper end highly.
Preferably, the（2）Step first carries out the before blow-down pipe is placed on stainless steel stent（4）Step.
Preferably, the saturating rate of the sky of the blow-down pipe is 60%.
Preferably, the（5）In step, the angle of inclination of blow-down pipe is 45 degree, in this angle, cleaning performance.
Emptying well original is designed as fibreglass reinforced plastic cover covering, and effective contact surface is only 0.09m2, using cylindrical blow-down pipe
Words, contact surface is 3.9m2, hence it is evident that increase effective contact area and improve emptying and aeration efficiency.Because of the life of one, two, three pond body
Thing filler forms suspension, a large amount of suspended biological fillers in liquid with liquid in pond.Pond body normally runs emptying and recoil mold cleaning
During formula, by adjusting 304 stainless steel stents, make the angle of inclination of blow-down pipe in the range of 40-50 degree, blow-down pipe is inclined at this angle
In the range of degree, the expulsion efficiency of gas is best；Biologic packing material recycles will deposit a large amount of mud at blow-down pipe for a long time, people
Work cannot enter pond body cleaning, coordinated using the high-speed gas of backwash tube and rinse the mud that blow-down pipe tapping adheres to, hence it is evident that subtracted
Few maintenance costs and recycling time.
In sum, by adopting the above-described technical solution, beneficial effects of the present invention have following several respects：
1st, construction cost is low, short time limit, and safe operation coefficient is high, and floor space is small during construction, simple and easy to apply；
2nd, can effectively prevent the biologic packing material in biochemistry pool from spilling emptying well, improve aeration efficiency；
3rd, the withdrawing fluid being vented in well emptying in time can be ensured and is lifted, so as to effectively prevent from blocking；
4th, empty rate blow-down pipe higher thoroughly effectively increases the emptying contact surface between blow-down pipe and sewage（Empty rate thoroughly is 60%
Blow-down pipe increased about 7.3 times of emptying contacts area compared with original fibreglass reinforced plastic cover is designed）, it is vented efficiency and substantially carries
Rise, and be aerated also more uniform；
5th, when blow-down pipe inclination 40-50 spends, at particularly 45 degree, its upright projection scope is located just at backwash gas scope
Interior, backwash gas rinse most uniform to blow-down pipe, rinse contact area maximum, backwash gas can be obtained into maximally effective
Utilize, the high-speed gas in lower end, backwash tube are most violent with emptying pipe friction when rising, emptying inside pipe wall attachment is become silted up
The cleaning effect of mud is also optimal；
6th, empty rate thoroughly is the ratio of the screen cloth hole gross area and total surface area, and it is to compare that empty saturating rate is limited in into 50-70% effects
Suitable scope.If too big, Stability Analysis of Structures has an impact blow-down pipe in itself, adds biologic packing material in liquid and the physics such as collides and makees
With, service life will be reduced, if too small, blow-down pipe is normally vented and mud cleaning will be affected, and easily blocks emptying
Well, causes to stop transport.
