Description
Technical field
The invention belongs to water-treatment technology field, in particular to a kind of pulse water distribution acidication petrifaction sewage treatment system and application method thereof.
Background technology
Petrifaction sewage has the features such as wastewater flow rate is big, water quality is complicated, toxic is big, variation water quality is big, concentration height, difficult for biological degradation, belongs to more difficult trade effluent. Therefore, it is necessary to petrochemical wastewater is carried out suitable preconditioning technique, to change its pollutent structure, reduce concentration of poisons, it is to increase its biodegradability. Acidication be a kind of anaerobic treatment process (fourth thunder, Qi Peishi, the first .2012. acidication technological effect appraisement system research of Zhao one. environmental engineering, 30 (6): 65-68). Suspension solid in waste water and macromole hard-degraded substance can be hydrolyzed to small-molecule substance and the voltaile fatty acid of dissolved organic matter and readily biodegradable by it, it is to increase wastewater biodegradability, thus improve the operating performance of subsequent biological treatment technique; Have load height, product mud is few, energy consumption is low, nutrient requirement amount is little, capacity of resisting impact load is strong, it is insensitive water temperature and pH to be changed, be easy to the features such as control simultaneously. Therefore, acidication process quilt is widely used in processing the petrochemical wastewater of difficult degradation.
In order to ensure fully contacting of mud and waste water in hydrolysis acidification pool, generally adopt the mode such as mechanical stirring, waterpower stirring to strengthen muddy water mixed effect more, practical application exists the shortcomings such as sludgd deposition, power consumption, equipment corrosion.
The water intake mode of hydrolysis acidification pool is divided into continuum micromeehanics and interval pulse water-feeding. Continuous Flow water inlet can realize more uniform cloth water, but has that head loss is big, water outlet holds susceptible to plugging problem. Pulsed water inlet can form bottom mud in high velocity fluid strikes pond, mud is fully mixed with sewage, and without the need to consumption of power, is relatively good water intake mode.
Pulse water distributing device generally can be divided into electric switch formula and hydrocone type. Electric switch formula is by automatic control device according to operating mode and processing requirement, and Controlling solenoid valve or motorized valve, form pulse. The control of electric switch formula pulse water distributing device is accurate, but equipment cost and running cost are all higher, and long-play, it is easy to break down.
Siphon type pulse water device utilizes the current of fast flow in siphon pipe to be taken away by the air in main pipeline, makes to be formed in main pipeline certain vacuum tightness, and inside and outside pipeline, under the effect of normal atmosphere, the water in container enters in pond after entering main pipeline.Owing to flow velocity is very fast, cloth water can complete within the short period of time, reaches the effect of pulse, stirs the mud at the bottom of pond so that it is constantly fully mixes with waste water in pond, and the organism in mud and sewage obtains sufficient contact reacts. Thus improve the muddy water mixed effect of hydrolysis acidification pool, it is to increase processing efficiency.
