Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment equipment, in particular to a fully automatically controlled wastewater discharge system. Background Art

[0002] The types and properties of wastewater are very complex, and the treatment purposes and requirements are also different. Therefore, it is often necessary to combine several treatment methods (or unit technologies) and reasonably configure their primary and secondary relationships and the order of precedence to form an organic whole, so as to achieve the treatment task most effectively and economically. This whole composed of several unit processes is called a wastewater discharge system, which is usually connected to the wastewater discharge end and is fully automatically controlled by an industrial computer.

[0003] At present, the commonly seen fully automatic wastewater discharge systems on the market are mostly similar in structure, consisting of several units such as primary sedimentation tanks, anaerobic tanks, aeration tanks, membrane biological filtration tanks, and dosing tanks. The discharged wastewater is precipitated, particles and floating objects are removed, and filtered before it is finally discharged. There are some functional deficiencies in actual use, and there is room for improvement. For example, most of the sediments in the wastewater accumulate in the primary sedimentation tank, and some sediments in the anaerobic tank will also be pumped back by the sludge pump. The sediments and water flow pumped back by the sludge pump can easily impact the sediments in the primary sedimentation tank, causing mud agitation. In addition, the flat-bottomed primary sedimentation tank is less efficient when discharging sludge, and is prone to residues, and does not have the function of facilitating centralized silt discharge.

[0004] Now, a new type of fully automatic controlled wastewater discharge system is proposed to solve the above problems. Utility Model Content

[0033] Working principle: When the utility model is used, first, the wastewater enters the primary sedimentation tank 8 from the wastewater inlet 14, and after sedimentation in the primary sedimentation tank 8, it enters the anaerobic tank 5. Under the action of anaerobic bacteria, the organic matter is hydrolyzed, acidified and methanized, and the organic matter in the wastewater is removed. Then the wastewater enters the aeration tank 4, and the activated sludge undergoes aerobic respiration and is further decomposed into inorganic matter. The treated sewage then enters the membrane biological reactor 3 to remove ammonia nitrogen and difficult-to-degrade organic matter. After a series of treatments, the reclaimed water enters the dosing sedimentation tank 2 for dosing. After sedimentation, it is finally discharged from the wastewater outlet 15. Most of the sediment in the wastewater is deposited in the primary sedimentation tank 8, and some of the sediments that are secondarily precipitated in the anaerobic tank 5 are pumped up by the sludge pump 6 and sent back to the primary sedimentation tank 8 through the sludge conveying pipe 7. Directly below the sludge conveying pipe 7, the stainless steel net bag 12 installed on the net bag mounting frame 11 receives the muddy water discharged from the sludge conveying pipe 7, relieves its impact force, reduces the impact on the sediment in the primary sedimentation tank 8, and makes it sink slowly, and is guided to the sludge discharge pipe 9 through the inclined guide plate 10 for centralized discharge.
