Description
Technical field
The invention belongs to field of environmental engineering, relate to a kind of individual cell sewage disposal system.
Background technology
One residential is the relatively independent region with a kind of function or several functions, and its drainage system is not generally within Municipal pipe network coverage. According to local environmental protection standard, it is necessary to arrange independent sewage treatment facility, here it is the small region sewage treatment of our indication.
The disposal ability of community wastewater system, various countries there is no unified restriction. The former Soviet Union once advised that the disposal ability of single structures was no more than 1400m3/d, and the U.S. is then limited to disposal ability in the scope of 3785m3/d. According to China's situation, it is proposed that sewage quantity is defined as small region sewage treatment factory in the treatment plant of below 4000m3/d.
Community wastewater is different from municipal sewage (often including part industrial wastewater), belongs to sanitary sewage category. Its water quality and quantity feature can be summarized as: water quality and quantity changes greatly, and pollutant levels are on the low side, namely low than municipal sewage, and Biodegradability of Wastewater is good, and intractability is little.
The function of water body that the process technique of community wastewater enters because of sewage is different and different, and conventional processing method has: then through filter-sterilized reuse etc. after anaerobic tank, coagulation (primary sedimentation pond), biological two stage treatment and two stage treatment.
Combination type treatment plant is once fashionable for a time, and combination type processes and refers to modular system that is that assemble or that be easily assembled to, and it has the advantages that construction is fast, does not account for greenery patches. But practical application shows, there is many problems. Such as the maintenance management difficulty of equipment, to ruuning situation examination inconvenience, it is limited that unit processes the water yield, all needs time verifying service life etc.
Cyclic Activated Sludge System (CyclicActivatedSludgeSystem is called for short CASS) is that a kind of Novel sewage grown up on SBR basis processes technique. This technique is at Sen Weirou wastewater treatment company of the U.S. and the New Wastewater Treatment Technique studying successfully also popularization and application for 1975 the earliest.
Summary of the invention
For solving the maintenance management difficulty of prior art device, to ruuning situation examination inconvenience, unit processes the technological deficiency that the water yield is limited, and the present invention provides a kind of individual cell sewage disposal system.
Individual cell sewage disposal system, processes equipment including one-level sewage disposal device and B-grade sewage, and described one-level sewage disposal device includes the setting pot, distribution well, CASS reaction tank and the contact chamber that are sequentially connected with; Described B-grade sewage processes equipment and includes the grit water separator that is connected with setting pot, the storage pool being connected with CASS reaction tank, and between the sludge dewatering being connected with storage pool.
Preferably, described setting pot includes coarse rack setting pot and the fine fack setting pot being attached thereto.
Preferably, also include between the chlorination dosing being connected with contact chamber.
Preferably, also include and the flushing pond being connected between sludge dewatering.
Preferably, the air blast machine room being connected with CASS reaction tank is also included.
Preferably, the grit water separator being connected with fine fack setting pot is also included.
Individual cell of the present invention sewage disposal system, technological process is simple, the method for operation is flexible, it is less to take up an area, and the fluctuation of the water yield, water quality can be cushioned by changing circulation time, there is stronger adaptability, be highly suitable for the popularization and application such as community, campus, industrial park.
Accompanying drawing explanation;
Fig. 1 illustrates one detailed description of the invention schematic diagram of the present invention.
Detailed description of the invention
Below the specific embodiment of the present invention is described in further detail.
Excellent field-electronic applications is as shown in Figure 1, coagulation mainly adopts Physical to take out float and partial organic substances, first the sewage that its specific embodiment is pipe network flow into the water management well that spouts, and makes sewage quantity and water quality adjusted, so that sewage disposal reaches operating stable equilibrium; Again by sewage respectively through thick, fine fack, the float thick to cut resistance; Then utilizing Gravity Separation principle in setting pot, separated by the bigger inorganic particles such as the sand grains in sewage, slag, sand sucker, then by sand setting sucking-off, delivers to grit water separator. The effect of setting pot is to be separated by the grit in sewage, it is prevented that its infringement to subsequent handling equipment, finally enters two stage treatment. Two stage treatment is on the basis of coagulation, physico-chemical process is adopted to remove the colloid in sewage and dissolved matter further, its main technique adopts CASS pond (including anaerobic pond, Aerobic Pond and sedimentation tank) T skill biochemical treatment, including: the sewage that coagulation is crossed initially enters anaerobic zone and carries out anaerobic treatment, after mud in anaerobic pond absorbs some harmful substances in sewage, sewage enters Aerobic Pond, thered is provided the oxygen needed for microorganism by aerator, be mixed into mixed liquor with activated sludge in pond; Then through aeration continuous, sufficient in Aeration tank, aeration makes activated sludge be in suspended state on the one hand, is fully contacted with waste water; On the other hand, by aeration, to activated sludge oxygen supply, keep aerobic condition, make microorganism normal growth and breeding, by the metabolism of microorganism, make that Organic substance is inorganization, noxious substance is innoxious; After sewage enters sedimentation tank, the mud person who lives in exile's sludge concentration tank after precipitation processes, and wherein the less supernatant of precipitated impurities is sent to anaerobic pond by sludge reflux pump again and is circulated process. Through CASS pond, contact chamber, after chlorination, water now has reached discharging standards.
Due to sewage treatment plant produce a large amount of mud contain harmful, noxious substance, surrounding can be had a negative impact, therefore it is necessary to mud is carried out in time process and dispose, so as to decrement, stable, innoxious and can be integrated into utilization. The process of mud includes the processes such as digestion, concentration. The primary sludge of preliminary sedimentation tank precipitation rises to gravity concentration tank by pump and concentrates. An activated sludge part for sedimentation in secondary sedimentation tank is risen to the anaerobic zone in CASS pond by reflux pump, to increase activated sludge concentration; Another part rises to floatation thickening pond by pump. Mud after 2 concentration basin concentrations, rises to digester by dosing pump and carries out digestion process. Finally enter and be dehydrated into more dry mud between dehydration and can transport outward process.
Above-described it is only the preferred embodiments of the present invention; described embodiment is also not used to limit the scope of patent protection of the present invention; therefore the equivalent structure change that the description of every utilization present invention and accompanying drawing content are made, in like manner should be included in protection scope of the present invention.
