Description
技术领域technical field
本发明涉及一种污水处理装置，尤其涉及一种分户生活污水处理装置。The invention relates to a sewage treatment device, in particular to a household sewage treatment device.
背景技术Background technique
对单户的生活污水进行就地处理有很多方面的优势，尤其适用在居住比较分散的地区，比如乡村。在这一方面，源自日本的小型净化槽是个典型的案例。但日本最小型的净化槽设计处理能力为1吨/天，而我国绝大多数的乡村家庭排水量显著小于1吨/天，因此迫切地需要研发适应更小规模排水的单户型污水处理装置。On-site treatment of single-family domestic sewage has many advantages, especially in areas with relatively scattered living, such as rural areas. In this regard, small purification tanks originating from Japan are a typical case. However, the design processing capacity of the smallest purification tank in Japan is 1 ton/day, and the drainage volume of most rural households in my country is significantly less than 1 ton/day. Therefore, it is urgent to develop a single-family sewage treatment device suitable for smaller-scale drainage.
为解决上述需求问题，国内市场上出现了一批模仿净化槽并缩小其体积的单户污水处理装置以满足乡村污水处理的需求，该批装置在污水总氮消除方面出现了以下两点问题：1)单级“缺氧-好氧”(A/O)工艺，仅靠沉淀区污泥硝化液回流至进水稳定区的过程实现后续的反硝化脱氮作用，难以平衡回流量、总氮去除量与装置总体运行效果之间的关系，导致装置脱氮效果不佳，出水总氮未能达到装置设定的排放标准；2)相比于其他功能区，体积较大的进水稳定区与缺氧区使得原本有机碳与总氮比值就低的生活污水中的有机碳源没有被脱氮反应充分利用，而是被简单的消耗，导致装置的脱氮效果不佳。In order to solve the above-mentioned needs, a batch of single-family sewage treatment devices that imitate purification tanks and reduce their volume have appeared in the domestic market to meet the needs of rural sewage treatment. These devices have the following two problems in the elimination of total nitrogen in sewage: 1) The single-stage "anoxic-aerobic" (A/O) process only relies on the process of returning the sludge nitrification solution from the sedimentation zone to the influent stabilization zone to achieve subsequent denitrification and denitrification. It is difficult to balance the return flow and total nitrogen. The relationship between the removal amount and the overall operation effect of the device leads to the poor denitrification effect of the device, and the total nitrogen in the effluent fails to meet the emission standard set by the device; 2) Compared with other functional areas, the influent stabilization area with larger volume With the anoxic zone, the organic carbon source in the domestic sewage with a low ratio of organic carbon to total nitrogen is not fully utilized by the denitrification reaction, but is simply consumed, resulting in a poor denitrification effect of the device.
为解决上述问题，市场单元与研发过程中出现了A/O工艺的2种衍生形式：多级A/O工艺和多段进水工艺。多级A/O工艺，是在装置体积不变的情况下，将缺氧与好氧功能区拆分成许多小单元并交叉设置，如公开号CN106630478A、名称为一种分散式污水处理装置及利用其进行污水处理的方法的中国专利，看似是实现了对有机碳的充分利用，提高了反硝化脱氮的程度，但是该工艺存在以下两点问题：1)多级A/O虽然没有缩短污水中大颗粒物质在缺氧功能区的停留时间，但在交叉设置的好氧功能区内大颗粒物是无法被消耗的，而且反硝化反应难以利用颗粒型有机物为有机碳源进行脱氮；2)增加了好氧功能区处理污染物的难度，存在生物系统崩溃的风险。In order to solve the above problems, two derivative forms of A/O process have appeared in the market unit and R&D process: multi-stage A/O process and multi-stage water inlet process. The multi-stage A/O process is to split the anoxic and aerobic functional areas into many small units and set them crosswise under the condition that the volume of the device remains unchanged. The Chinese patent on the method of using it for sewage treatment seems to realize the full utilization of organic carbon and improve the degree of denitrification and denitrification, but the process has the following two problems: 1) Although multi-stage A/O does not Shorten the residence time of large particulate matter in the sewage in the anoxic functional zone, but the large particulate matter cannot be consumed in the cross-set aerobic functional zone, and it is difficult for the denitrification reaction to use the particulate organic matter as the organic carbon source for denitrification; 2) It increases the difficulty of treating pollutants in the aerobic functional area, and there is a risk of the collapse of the biological system.
多段进水工艺，是对接纳进水的功能区进行分配，将一部分进水直接流入对有机碳源有需求的缺氧功能区，以实现对有机碳源的充分利用，如专利：(CN10812896A)，该工艺也存在2点问题：1)非工艺起点进入的污水，在装置内的停留时间将会被缩短，势必会导致处理效果下降，限制了多段进水的水量分配；2)进水中需要经过沉降或上浮过程才能被去除的大颗粒污染物较多，不但难以被反硝化反应所利用，而且增大了缺氧功能区的处理负荷。The multi-stage water inflow process is to distribute the functional areas that receive influent water, and part of the influent water directly flows into the oxygen-deficient functional area that requires organic carbon sources, so as to fully utilize the organic carbon sources, such as patent: (CN10812896A) , this process also has 2 problems: 1) The residence time of the sewage entering the device at the non-process starting point will be shortened, which will inevitably lead to a decrease in the treatment effect and limit the water distribution of the multi-stage influent; 2) The influent There are many large-particle pollutants that need to be removed by sedimentation or floating process, which is not only difficult to be utilized by denitrification reaction, but also increases the processing load of the anoxic functional area.

Under the action of the overflow weir in the upper part of the area, the treated sewage flows into the overflow area evenly and homogeneously, and flows into the overflow tank and the first aerobic area connected with the overflow area.
污水进入第一好氧区后在悬浮污泥和生物悬浮球填料表面附着的生物膜的共同作用下进行有机物的降解和氨氮的氧化，在这个过程中，部分有机物被吸附氧化分解，转化成CO2排出，另一部分发生合成代谢，用于微生物的增殖，处理后的水经隔板底部的穿孔进入第二缺氧区。由于生物膜的截留作用，第一好氧区中具有较高的微生物浓度，从而提高了污染物的去除率；After the sewage enters the first aerobic zone, the organic matter is degraded and the ammonia nitrogen is oxidized under the combined action of the suspended sludge and the biofilm attached to the surface of the biological suspension ball filler. During this process, part of the organic matter is adsorbed, oxidized and decomposed and converted into CO 2 is discharged, and the other part undergoes anabolism for the proliferation of microorganisms, and the treated water enters the second anoxic zone through the perforation at the bottom of the partition. Due to the interception effect of the biofilm, the first aerobic zone has a higher concentration of microorganisms, thereby improving the removal rate of pollutants;
污水进入第二缺氧区后，在悬浮污泥和网状生物填料表面附着生长的厌氧及兼性厌氧微生物的共同作用下，进一步进行有机物的降解和反硝化脱氮，由于氧气的缺乏，部分来自第一好氧区的微生物逐渐死亡而释放出胞内物质，同时第二缺氧区内生长的厌氧微生物分泌的胞外酶也可促进这部分微生物的降解，转变成新的有机物，从而为反硝化补充碳源，而且第二缺氧区还接纳了由第一缺氧区经溢流槽流入的污水，进一步补充了该区脱氮反应所需的碳源，强化了装置的脱氮效果。处理后的水通过隔板上部的溢流孔进入第二好氧区；After the sewage enters the second anoxic zone, under the combined action of the anaerobic and facultative anaerobic microorganisms attached to the surface of the suspended sludge and the reticulated biological filler, the degradation of organic matter and denitrification and denitrification are further carried out. , some microorganisms from the first aerobic zone gradually die and release intracellular substances, while the extracellular enzymes secreted by anaerobic microorganisms growing in the second anoxic zone can also promote the degradation of these microorganisms and convert them into new organic matter , so as to supplement the carbon source for denitrification, and the second anoxic zone also accepts the sewage flowing in from the first anoxic zone through the overflow tank, which further supplements the carbon source required for the denitrification reaction in this zone and strengthens the device’s performance. Nitrogen removal effect. The treated water enters the second aerobic zone through the overflow hole in the upper part of the separator;
第二好氧区对污水处理的过程类似第一好氧区，但由于经过稳定区、第一缺氧区、第一好氧区和第二缺氧区的处理后，大部分有机物已得到去除，第二好氧区内主要发生硝化反应，以充分去除氨氮。处理后的水从隔板底部的穿孔流入沉淀区；The process of sewage treatment in the second aerobic zone is similar to that in the first aerobic zone, but most of the organic matter has been removed after the treatment in the stabilization zone, the first anoxic zone, the first aerobic zone and the second anoxic zone , the nitrification reaction mainly occurs in the second aerobic zone to fully remove ammonia nitrogen. The treated water flows into the sedimentation zone from the perforations at the bottom of the separator;
在沉淀区中，一方面，通过沉淀去除水中含有的少量悬浮固体，并从出水管排出；另一方面，沉淀区上部可设置气提回流装置，气提回流装置通过气提作用将过程中产生的剩余污泥或脱落的生物膜与硝化液一并提至稳定区。In the precipitation zone, on the one hand, a small amount of suspended solids contained in the water are removed by precipitation and discharged from the water outlet; The remaining sludge or the shed biofilm is lifted to the stabilization zone together with the nitrification solution.
