Description

1241988 (1) Description of the invention: [Technical field to which the invention belongs] The present invention relates to a water treatment equipment, in particular a water treatment equipment and a water purification program that combine sedimentation and transition with biological contact aeration mechanisms. [Previous technology] Usually the purpose of implementing raw water, sewage or wastewater treatment is to purify the water to make it meet the standard of raw drink or discharge. Regardless of the source of the water, such as ocean, river, well water, or rainwater, the reverse osmosis method is generally used as the net 10 15 water means. For the latter, depending on the source of sewage and wastewater to be treated, the anaerobic chemical treatment method, the aerobic activated sludge method and the biological contact aeration method, etc., or a combination thereof can be used to achieve the required discharge standard; For example, the treatment of livestock farm sewage and wastewater often uses a combination of chemical coagulation sedimentation method and activated sludge method or biological contact aeration method. However, no matter whether the reverse osmosis method is used to purify the raw water, or the chemical coagulation and sedimentation method is used to treat the sewage and wastewater of various production businesses, although it can achieve a similar degree of water purification effect, it is necessary to use chemical agents. In the process, a large amount of medicines will be consumed, and the amount of sludge generated will be too much and the remaining chemical agents may be possible and the ancient master ^ Yu Yongzheng is toxic, so it cannot be used directly as an organic fertilizer, and it is not suitable. Jijiege, Zhi ^ and directly buried, and must be further processed, ¥ caused an increase in processing costs. In addition, the efficiency of water purification by the above methods is limited. Take the reverse osmosis method as an example. The amount of water available for raw drinking in the second and third treatments is only about 30% of the water input. ul. The weighting ratio of the produced wastewater is about 70%. In addition, the activated sludge method is wonderful and ancient, although it is friendly to the environment and the substrate is mixed. 20 1241988 Uniformity, good handling and low equipment cost. # The advantages are comparable in the process. It swells to a large extent and has a large amount, so it is necessary to treat the expanded product, which is not conducive to the operation of treating a large amount of sewage and wastewater. As for the biological contact aeration method produced by the good activated sludge method, the biological phase is relatively abundant. Although the π mud is small and easy to settle, it has the problems of being easily blocked by contact with ferrous materials and lacking flexibility. Although the combined activated sludge method and biological contact aeration method have been proposed to treat slaughterhouse forests and wastewater, it has also been obtained that compared with the pure active 10 15… Nipha can reduce the amount of sludge by about one-third. However, in the case of large-scale treatment, the amount of sludge produced is still quite disturbing, and further steps need to be taken to reduce the volume of sludge. Therefore, the existing water treatment equipment is limited by the large amount of sludge to be further processed. The Shen Dianchi, which is configured by households, can only handle up to 500 to 2000 metric tons of water, and the scale is limited. However, although the raw water treated by reverse osmosis method contains relatively few impurities or is less affected, taking river water and well water as examples, first removing sand and foreign matter, sterilizing, and dechlorinating: 1: 2 requires m, , .L set / special edition, turbidity removal and other steps. In addition, the industry discharge water and air pollution also contain many heavy metals, so even if the raw water is seawater, other than 1 medium =, the content of metals such as mercury and lead is also high, and this-is removed by reverse osmosis. Erduyu can not pass through for a long time [Content of the invention] The main purpose of the present invention is to provide a large amount of water, which produces a small amount of sludge and can directly treat a wide range of water sources that can be treated during X, X, and treatment. Treatment; 7 machine fertilizer use, same as 20 1241988. Water in this unit performs sedimentation and filtration at the same time, that is, the sludge settles in the base of the funnel first. After the preliminary sedimentation, the upper layer of water enters the filtration tank to filter out the suspension. Impurities, thereby reducing the organic load of subsequent contact aeration treatment. In order to maintain the effective filtering function of the filter yarn in the rapid water purification filter, in addition to the automatic timing of the backwash time, the present invention may further be equipped with an ultrasonic oscillating device 90, so as to backwash the filter tank. In the cleaning program, the ultrasonic vibration effect is used to quickly and efficiently clean the filter yarn in the filter tank. In addition, the biological contact aeration unit of the present invention can be aerated by one or more biological contacts depending on the water source of the water to be treated. Pool, where each biological aeration tank can be composed of a front aeration tank and a rear aeration tank, and the two can be the same or not [5] 'but at least one of the tanks also includes aquatic biofilm contact Contact with underwater biofilm. The contact filter material of the above-mentioned biofilm contact portion is not immersed in water, and the contact filter material of the underwater biofilm contact portion is completely immersed in water. The aquatic biofilm contact part is made of pp, pE or wood filter material suitable for algae attachment growth, and j is preferably a wood filter material. In addition, a plurality of water spray heads are arranged above the filter material, so that the water to be treated can be removed from the water spray head and the skin. When spraying to the process of contacting the wooden filter material, first contact the air for the first stage of dissolved oxygen; and when the wooden filter material is contacted, the oxides contained in the water can provide the algae growth, and then use the photosynthesis products of algae to further make the flow The second stage of dissolved oxygen is carried out by the water passing through the wooden filter material; in this way, the water to be treated flowing into the contact portion of the underwater biofilm can have a higher amount of dissolved oxygen. In addition, the aquatic biofilm contact part is such that the wooden 1241988 filter material is about 50 cm ~ loo cm from the water surface of the underwater biofilm contact part. In addition, the underwater biofilm contact part uses plastic materials such as pp, pE, and pvc. Material or wood filter material, and increase the dissolved oxygen by the air waterfall generating device. The sludge sedimentation unit used in this volume of water treatment equipment consists of a 5 body with a cylindrical body and a Shifan; *: 4 + Shihan Mu 5 continuous scraping device rotating on the body The sedimentation tank is used to effectively remove the sludge at the bottom of the tank. In addition, the cylindrical body of the sedimentation tank is further provided with a post extending upward from the center of the bottom of the tank for the above-mentioned mud scraping device to be mounted thereon as a pivot fulcrum. In addition, the column is near the top of the pond and is provided with a funnel-shaped mud collecting tank surrounding the body of the body, which is used to collect the settled sludge on the top of the pond, so as to avoid interference from the rotation of the scraper. Disperse it into water again, so that the pond's mud removal efficiency can be improved. Moreover, in order to prevent the water flow entering the Shen Dianchi from interfering with the sedimentation effect of the round body of the Shenying pool, the cylindrical body is further provided with an annular spreading plate on the periphery of the mud collecting tank. Since the water treatment equipment of the present invention uses physical filtering, sedimentation, and biological contact aeration to remove sludge, the activated sludge tank is not used in the process, and the rapid water purification filter used in the book describes In addition to suspended impurities, the same amount of microorganisms that are naturally present in the water to be treated is also lost. Therefore, in the newly opened water treatment equipment, the source of the microorganisms in the aeration tank is the first batch to be treated. The water is obtained by accelerating the culture for several days with aeration. After that, in addition to the cultivation of the aeration tank, the sludge discharged from the Shen Dianchi can be caught back to the aeration tank to increase the concentration of microorganisms. Therefore, the microorganisms used in the biological contact aeration stage of the present invention will depend on the source of the water to be treated, that is, the common microorganisms in ordinary activated sludge, such as Paramecium aurelia 1241988, Phyllosoma timophylla (Trachelophyllum pusillum), Aspidisca costata, Vor-ticella microstoma, Epistylis plicatilis, Vorticella convallaria, Euplotes patella, Setia 5 (Opercularia coarctata), Chilodonella uncina-ta, Hemiophrys fusidens, Vorticella al-ba, Carcaceium polypinum, swimmer Euplotes mocbiusi, Paramecium trichium, Euplotes affinis, Chilodonella cucullulus, Drepano-_ 10 monas revoluta, Varticella striata revoluta, Colpidium colpoda and small flagellates. Among them, in the seawater desalination process, small flagellates, whole caterpillars, tubeworms, naked mouths, white bellworms, worms, parasites, paramecium, parasites, tuberworms, etc. It is better to be used as biological contact aeration treatment bacteria; in the treatment of sewage and wastewater, it is better to use ordinary activated sludge microorganisms, such as tuberworm, ribbed fiberworm, small mouth bellworm, Gulch beetle, Set cover worm, Ancylostoma sp β The water treatment equipment of the present invention can combine the rapid sludge filtration, unit, biological contact aeration unit and sludge sinking unit according to the source of the water to be treated. The combination of different groups of 20 numbers and installation order can also be added as needed, such as , Sewage barrier to remove large impurities and oil in the water to be treated, or a sludge dehydrator to reduce sludge volume. For example, when the source of the water to be treated is seawater, a first rapid filter, at least one aeration tank including an underwater biofilm contact part and an aquatic biofilm contact part, and a cylindrical Shendian pond A sludge 10 1241988 A dehydrator and a second rapid water purifier were connected in sequence to form a seawater treatment equipment. In addition, if the water to be treated is domestic sewage, a pollution prevention fence can be installed before the first rapid filter of the aforementioned seawater treatment equipment to constitute a people's livelihood &gt; water treatment equipment; a pollution prevention fence, a first A cylindrical Shendian pond, at least one aeration tank including an underwater biofilm contact part and an aquatic biofilm contact part, a second cylindrical sedimentation tank, a sludge dehydrator, and a second rapid water purification filter The machines are connected in order to form industrial sewage and wastewater treatment equipment. Since the water treatment equipment of the present invention uses physical filtration, sedimentation, and biological contact aeration to remove mud, compared with the traditional chemical treatment method or _ activated mud method, the sludge produced in the water treatment process The amount is small and does not contain toxic chemicals, and the generated sludge can be partially returned to the contact aeration tank to maintain the microbial concentration, and the rest can be directly used for planting plants or after simple dehydration. The use of organic fertilizers can reduce the use of chemical agents, omit the sludge treatment process and greatly reduce the cost of water treatment, and it does not increase the burden on the environment at all, and meets environmental protection requirements. The water treatment equipment of the invention can be applied to the treatment of raw water, so that the treated water can meet the standard of raw drinking water up to 99% of the amount of water; when the spring is used to treat the sewage or industrial wastewater, it can not only achieve drainage Standards can even be recycled. [Embodiment] The water treatment equipment, features, and effects of the present invention will be described in detail with reference to the preferred embodiment of the drawings.
