4)以AHRT为X轴，以OURc和OURn分别为Y轴，用作图软件制作出关系图，并分成不同区域，如图2所示；4) Take AHRT as the X-axis, and use OURc and OURn as the Y-axis respectively, use the diagram software to make a relationship diagram, and divide it into different regions, as shown in Figure 2;
5)根据AHRTmin、OURcmin和OURnmin曲线将关系图分成不同区域；5) According to the AHRT min , OURc min and OURn min curves, the relationship diagram is divided into different regions;
6)从图2中可以看出，①区域为最优区域，其中，AHRT较大，可以完成COD在厌氧和缺氧条件下大量去除，同时OURc在满足自身生长增殖的基础上较小，不会与自养菌发生很大的竞争，OURn较大可以有较高的脱氮效率，所以满足下述条件的区域为污水处理最优区域：同时满足AHRT>AHRTmin、OURc>OURcmin、OURn>OURnmin的区域；6) It can be seen from Figure 2 that area ① is the optimal area, in which AHRT is relatively large, and COD can be removed in large quantities under anaerobic and anoxic conditions, and OURc is relatively small on the basis of satisfying its own growth and proliferation. There will be no great competition with autotrophic bacteria, and a larger OURn can have a higher nitrogen removal efficiency, so the area that meets the following conditions is the optimal area for sewage treatment: simultaneously satisfy AHRT>AHRT min , OURc>OURc min , OURn>OURn min area;
7)通过控制工艺中AHRT的变化，进而影响OURc和OURn，调节其向最优区域靠近。调控AHRT的方式具体为：调整进水量、回流量及池容量。7) By controlling the change of AHRT in the process, and then affecting OURc and OURn, adjust them to approach the optimal area. The way to regulate AHRT is as follows: adjust the water inflow, return flow and pool capacity.
实施例分析：Example analysis:
我们可以发现在现有固定的水质条件下，不同区域的呼吸图谱参数和AHRT所代表的MAAO工艺性能的特点，决定每个区域大小和位置。图2分为6个区域，分别是由AHRTmin、OURcmin和OURnmin区分的。We can find that under the existing fixed water quality conditions, the parameters of the respiration map in different regions and the characteristics of the MAAO process performance represented by AHRT determine the size and location of each region. Figure 2 is divided into 6 regions, which are distinguished by AHRT min , OURc min and OURn min .
①号区域为现有水质条件下的合理配置区域，AHRT比较大，可以完成COD大量消耗在厌氧缺氧区的目标，OURc不是很小，可以完成污泥所必须的生长增值要求，OURn较大，可以完成脱氮要求，代表工况为工况一与工况二，在此区域内，AHRT与OURn越大，则系统脱氮能力越高。①号区域是同时满足AHRT>AHRTmin、OURc>OURcmin、OURn>OURnmin的区域，为最优区域。Area ① is a reasonable allocation area under the existing water quality conditions. AHRT is relatively large, which can achieve the goal of COD consumption in anaerobic and anoxic areas. OURc is not small, and can complete the growth and value-added requirements necessary for sludge. Larger, the denitrification requirements can be fulfilled, and the representative working conditions are working condition 1 and working condition 2. In this area, the larger AHRT and OURn are, the higher the denitrification capacity of the system is. Area ① is the area that satisfies AHRT>AHRT min , OURc>OURc min , OURn>OURn min at the same time, which is the optimal area.
②号区域的AHRT太短，无法完成COD的合理配置，会在好氧池消耗一定的COD。此时OURc太大，OURn太小，脱氮效果非常差，代表工况为工况三和工况四。③号区域和④号区域都是②号区域下的不同分区，均为AHRT太小，OURc太大，但是③号区域的OURn较高，符合一定的脱氮要求，而④号区域的OURn较低，脱氮效率较低。此时最有效的调节方法是通过减少进水量或增大池容，从而增大AHRT，使其达到最优区域；② The AHRT in area No. 2 is too short to complete the reasonable allocation of COD, and a certain amount of COD will be consumed in the aerobic pool. At this time, OURc is too large, OURn is too small, and the denitrification effect is very poor, and the representative working conditions are working conditions 3 and 4. Area ③ and Area ④ are different divisions under Area ②, both of which have too small AHRT and too large OURc, but the OURn of Area ③ is relatively high, which meets certain denitrification requirements, while the OURn of Area ④ is relatively high. Low, the denitrification efficiency is low. At this time, the most effective adjustment method is to increase the AHRT by reducing the water inflow or increasing the pool capacity, so that it reaches the optimal area;
⑤号区域的AHRT较大，但是OURc或OURn很小，一般不会出现此种情况；The AHRT of area ⑤ is relatively large, but OURc or OURn is small, which generally does not occur;
⑥号区域的AHRT合适，OURn也满足脱氮的要求，但是此种情况的AHRT特别大，由于污泥在厌氧缺氧和好氧条件下的能量转化效率不同，其完成必要的生长增殖时必须要有一定的OURc要求，而本区域的OURc太小，对污泥生长不利，这种情况的代表工况为工况五。此时，需要在保证足够的AHRT的条件下，减小AHRT，增大进水量或者减少池容量，从而增加OURc，来保证污泥的生长。The AHRT of area ⑥ is suitable, and OURn also meets the requirements of denitrification. However, the AHRT in this case is particularly large. Due to the difference in energy conversion efficiency of sludge under anaerobic-anoxic and aerobic conditions, it takes time for the sludge to complete the necessary growth and proliferation. There must be certain OURc requirements, but the OURc in this area is too small, which is not conducive to the growth of sludge. The representative working condition of this situation is working condition five. At this time, under the condition of ensuring sufficient AHRT, it is necessary to reduce AHRT, increase water intake or reduce tank capacity, thereby increasing OURc to ensure the growth of sludge.
