Description
Technical field
The present invention is that the one related in water supply and sewage work tackles seasonal high turbidity raw sewage treatment process, is specifically a kind ofly applied to the combined treatment process of taking seasonal high turbidity raw sewage waterworks.For the high turbidity raw sewage that seasonality occurs, former water preliminary sedimentation and sludge condensation process are combined, realize water factory's effluent quality under the different operating mode of former water height low turbidity up to standard, and realize producing concentrated, the dehydration of mud and the optimum combination treatment process of characteristic energy changes simultaneously.
Background technology
Containing gas chromatography and inorganics in the water inlet of city tap-water factory, earth surface water source is subject to the factors vary such as flow and water temperature at the change of season, occur that turbidity significantly raises in short-term, water factory's treatment scheme cannot be tackled, produce a large amount of factory effluent simultaneously and discharge technical process as production by product, larger pressure is produced to surrounding enviroment, becomes environment and social concern that city tap-water factory must solve.
At present, before conventional sedimentation and filtration process, generally adopt simple preliminary sedimentation procedure to deal with the seasonal high turbidity water quality occurred in the waterworks of taking high turbidity raw sewage, and contained mud impurity is often treated as source of pollution in factory effluent, by concentrated, natural mummification or mechanical dehydration, contained production mud in factory effluent is transported outward with the form of solid body, to reduce the impact on environment.The main drawback of above-mentioned technology is after ultra, raw water of waterworks present continue comparatively low turbidity time, preliminary sedimentation procedure cannot play a role in treatment process, and factory effluent drain time is generally comparatively concentrated, process structures floor space is comparatively large, and running cost is higher, and concentrated supernatant and dehydration filtrate are often more difficult reaches emission standard, wherein large amount of organic becomes environmental pressure again as pollutent, has become the technical barrier of seasonal high turbidity raw sewage process.
Summary of the invention
The object of this invention is to provide a kind of seasonal high turbid original sub-block technique, be suitable for the combined treatment process under seasonal high turbidity raw sewage condition, overcome the conventional art prejudice that water and mud process respectively, preliminary sedimentation process, sedimentation and filtration, sludge concentration and dewatering and waste water reclamation and characteristic energy changes function are combined, while guaranteeing that treatment process effluent quality is up to standard, the thickening of realization production spoil disposal water, sludge treatment tail water qualified discharge and Organic substance in water are converted into the function that bioenergy reclaims further.
To achieve these goals, technical scheme of the present invention is: a kind of seasonal high turbid original sub-block technique, it is characterized in that former water is introduced into after preliminary sedimentation concentrates reuse tank preliminary sedimentation, water outlet enters settling tank precipitation, after precipitation water outlet enters filter, water outlet enters after clean water basin regulate and store, pressurizeed by repumping house and send into city planting ductwork, the spoil disposal access counterbalance cell that preliminary sedimentation concentrates reuse tank stores, mud extraction enters dehydration machine room and carries out processed, deviate from the outward transport of dry mud to dispose, filtrate enters concentration mass energy conversion pool.
According to one embodiment of present invention, when water factory place is nervous and construction fund is well-to-do, depositing technology can be considered to adopt floor space little and band sludge reflux and the efficient sedimentation tank of concentrating function, and the spoil disposal of efficient sedimentation tank and preliminary sedimentation concentrate reuse tank spoil disposal and after counterbalance cell is regulated and stored, enter dehydration machine room in the lump carry out processed.
According to another embodiment of the present invention, when water factory's land used is well-to-do and construction fund is more nervous, depositing technology can consider the horizontal sedimentation tank that employing floor space is larger or tube settler, horizontal sedimentation tank or tube settler spoil disposal access spoil disposal pond after promote enter concentration basin concentrate, concentration basin supernatant liquor enters concentration mass energy conversion pool, and concentration basin spoil disposal and preliminary sedimentation concentrate reuse tank spoil disposal and after counterbalance cell is regulated and stored, enter dehydration machine room in the lump carry out processed.
After filter cell rinse waste water enters blowoff basin, with former water mixing reuse after general lifting, under emergency condition, enter concentration mass energy conversion pool.Concentration mass energy conversion pool accepts dehydration machine room filtrate and blowoff basin and meets an urgent need after draining and carry out in-depth process, and partial organic substances is converted into bioenergy and reclaims, and all the other mud carry out sludge drying process; Concentration mass energy conversion pool filtrate can enter blowoff basin promote after as former water conservancy use, or up to standardly enter river water body.At ordinary times during low turbidity operating mode raw water turbidity lower than 200NTU or sediment concentration lower than 0.20kg/m
3, former water can surmount preliminary sedimentation and concentrate reuse tank and directly enter settling tank process; When raw water turbidity more than 200NTU or sediment concentration at 0.20 ~ 3.5kg/m
3time, former water first should concentrate after reuse tank preliminary sedimentation through preliminary sedimentation and enter settling tank process again; When former water sediment concentration is more than 3.5kg/m
3time, former water first should be introduced into settling pit sand setting at dry point place, and water outlet concentrates reuse tank through preliminary sedimentation again and enters settling tank process.Before sediment outflow pond and preliminary sedimentation concentrate reuse tank, add potassium permanganate, add PAM, before efficient sedimentation tank, add alum before sediment outflow pond and preliminary sedimentation concentrate reuse tank He in efficient sedimentation tank, chlorination before and after clean water basin, adds burgy after settling pit.
Sand setting process, sedimentation and filtration, sludge concentration and dewatering and waste water reclamation and characteristic energy changes function combine by the present invention, first the Treatment for Reuse of factory effluent and preliminary sedimentation are combined, be arranged on settling tank in the past as a part for water-purifying process, and the supernatant liquor produced in wastewater treatment and dehydration filtrate are carried out characteristic energy changes, the organism of part is converted into bioenergy.The different coprecipitation modes that the present invention adopts according to treatment process, classify treatment process, then according to different operational conditionss and requirement, form the complete process system of two cover treatment process compositions.The advantage of this technique is to adapt to different former regimen condition and operating requirement, water for drainage slurry technique and water-purifying process are combined, the seasonal high concentrtion of simultaneous adaptation and at ordinary times low turbidity operating mode, factory effluent is concentrated with dewatering process in be easy to the concentration basin supernatant liquor of discharge beyond standards and dehydration filtrate concentration mass energy conversion pool carries out secondary treatment, efficiency utilization structures processing power, to save floor occupying area, realizes organism in the discharge of water-purifying process standard water discharge and factory effluent and is converted into the effect that bioenergy reclaims further.
