Explanation of the invention (/) The present invention is an active sludge tank toilet system 'which can efficiently and effectively handle the slaughterhouse wastewater in a combined manner: slaughter: There are four treatment methods commonly used in the wastewater of the slaughterhouse (Johnset, an_ath et a1 ., 2_) ·· 1. Anaerobic treatment + activity =,; 2. Anaerobic treatment + contact aeration method; 3. Activated sludge method + chemistry; Weight / child drop method, 4. Contact aeration method + chemistry Coagulation sedimentation method. Among the above four methods, if the anaerobic treatment system is used, the space required is large; while the use of chemistry ~, "L to the one drop method", in addition to the large consumption of drugs required, and There is also a large amount of sludge production. Among them, activated sludge method is one of the most traditional biological treatment methods, and is widely used in various wastewater treatment. Its advantages are basic elasticity and low equipment cost. The amount of mud; operation: not easy to be shortcomings. The contact aeration method is improved from the activated sludge method. In the activity> sludge aeration tank, biological contact materials are placed to change the suspended biological phase. The solid biofilm-based biological phase has the advantages of more biological phases, less sludge volume, and easy sedimentation of sludge, but it has the disadvantages of easy clogging, non-operational flexibility, and increased cost of biological contact with filter media. (Nakajimaj etal · (2000) In summary, for slaughterhouses with a lot of organic pollutants, there have always been problems in using this type of sewage treatment system, such as the processing speed, the cost of excessive material consumption, and so on. Therefore, for this stage at this stage, Wastewater treatment Legally, an effective and efficient treatment system and system can be said to have urgent needs.

When the wastewater is pumped from the regulating tank to the first tank of the biological treatment system, the concentration of the substrate in the water is the highest, and the impact on the biological system is the largest. In order to make this impact 521065 B7 V. Description of the invention (7) The time is reduced to the shortest, only fast mixing In order to reduce the impact of the impact, the two activated sludge tanks in the front section of the system are free from biological contact filters and materials (please read the precautions on the back before filling this page). 7-It can quickly disperse high-concentration substrates effectively. Open And the matrix premenstrual f - a sludge & decomposition I, the concentration will be low down%, when # is brought into contact aeration tank, biological impact is relatively small. Contact eve; Improved tendons, the system mostly operates under high organic load, and its biological phase is mostly Paramecium, flagellates, etc .; After the improvement, observe the system ’s biological insects. The current biological phase is obviously changed to swimming ciliates. And the stalk-like ciliated ^ the same day and the emergence of rotifers and crustaceans and other protozoa, showing that the system can effectively increase the concentration of activated sludge, and effectively reduce the organic load. Because the suspended microorganisms in the activated sludge tank directly flow into the contact aeration tank of the fixed biological system, some of them will adhere to the biological contact filter material to form a biofilm ', and some will suspend and grow between the biological contact filter materials. The biofilms and suspended microorganisms in the biological contact aeration tank will undergo solid-liquid separation in the sedimentation tank and return to the activated sludge tank. Therefore, each biological aeration tank has activity; The biological phase of the system and the biological phase of the attached system biofilm. At the same time, the sewage was observed by an electron microscope. It was also found that there were many microorganisms of various sizes with strong activity in each pond. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Suspended microorganisms flow directly into the fixed biological system, and some of them will be decomposed after being adsorbed by the fixed biofilm. The aging biofilm falling off from the biological contact aeration tank will settle in the final settling tank, and then return to the activated sludge tank, which will also be degraded by activated sludge bacteria of different biological phases. Due to the jumping relationship between different biological phases, the amount of biological sludge can be greatly reduced. The amount of sludge from the original activated sludge method was 3830 kg / day, but after the improvement of the present invention, the amount of sludge became the paper size applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 public love) 521065 V. Description of the invention ( β) 2200 kg / day 'It can be seen that the sludge volume of the combined system is indeed less than that produced by the traditional sludge process. Because the aeration tank in front of the sedimentation tank is a contact aeration tank, it belongs to an attached biological system, and the proportion of the shed biofilm is larger than that of the microorganisms in the suspension system: so the sedimentation is rampant. However, the activity from the previous stage to the suspension suspension of% is also mostly settled after colliding with the biofilm and attracting each other, so the overall settlement is much better than the activated sludge system. It can be seen from the seventh figure, 纟 3, and Table 4 that when the SS inflow concentration is between 12Q ~ _ mg / L, the SS content in the outflow water of the system treatment 2 can be maintained between 5 ~ 59 mg / L, so that the removal Efficiency is up to 96%. From the eighth figure, the effluent% value above 70% is less than 20%. Because the high-concentration substrates are all in the activated sludge tank, they are fully stirred, diffused, diluted, and biodegraded. The concentration of the substrate flowing to the rear contact aeration tank has been reduced, resulting in the biofilm thickness not being too thick and the biofilm falling off The probability is lower, so the chance of biological contact with the filter material is blocked. The removal effect of true color chromaticity is shown in the ninth figure. The true color chromaticity can be reduced to 45 mg / L, and the removal efficiency is about 77%. The oil removal effect is shown in the tenth figure. The average concentration of oil in the effluent water is 6.6 mg / L, and the average removal rate is 88%. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, therefore, 'This system is applied to the wastewater treatment of this slaughterhouse.

Description of the invention (5 · Sludge age (SRT) · 9 · 9 4 day s 6. Sludge return rate: 30 ° / 0 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs It can be known from the experimental results that after the treatment of this system, the original activated sludge system The COD value of the effluent water is between 150 ~ 200 mg / L, and the SS value is between 80 ~ 100 mg / L. The COD value of the effluent water is changed to a two-phase biological treatment system of activated sludge / biological contact aeration tank. The SS value and the SS value were reduced to about 40 mg / L and 22 mg / L, respectively, showing that the water quality after the treatment has been excellently improved in all aspects. In summary, the present invention adds a biological contact filter material in the second half of the aeration tank. To make it a two-phase hybrid tandem biological treatment system of activated sludge / biological contact aeration tank, without increasing the use space and power consumption of the wastewater plant, the minimization of the sludge production of wastewater treatment, the release of water and SS also Reduce a lot. Because the microbial phase becomes complex and complete, The material treatment system is quite stable and easy to operate. At the same time, it has the advantages of uniform matrix mixing, flexible operation, more biological phases, less sludge volume, easy sedimentation of the sludge, non-bulging, non-blocking, and good effluent quality. Compared with the activated sludge method, the present invention has the advantages of more cost of biological filter material, but less than the amount of biological filter material used in the contact aeration method, so it can indeed solve the shortcomings of the current slaughterhouse π water treatment system and Disadvantages, significant competition, and excellent industrial applicability, so the invention patent application is filed. 11 This paper size applies to China National Standard (CNS) A4 specification (21〇χ 297 mm) (Please read first (Notes on the back, please fill out this page) f Order il · ------ line ·
