Due to the huge investment problems involved in the special pipeline network and factories and stations for sewage treatment, it cannot be realized. It is only a residential unit. Or single buildings have been treated with simple septic treatment. Therefore, on the one hand, it seriously pollutes the water body and deteriorates the ecological environment. On the other hand, the renewable resources contained in domestic sewage are wasted in vain. Therefore, domestic and foreign Has been trying to find a method and efficient device that can not only purify, but also recycle, and reduce huge urban municipal investment.
为了解决这一问题，一种标准公告号为DB43/T139-1999的介绍了《生活污水净化沼气池标准图集》和专利公告号为CN2275579Y的介绍了《高效无能耗生活污水处理装置》，两者的结构和工艺基本相同，均为厌氧前处理和好氧后处理，是目前国内比较先进的生化处理装置，净化后的污水能达标排放，但由于采用了传统的水压式机构和软填料及硬滤料装置，所以处理的长期效果一般较差、效率不高、出料和管理困难，不同的是前者向人们展示了一个在低浓度的生活污水中可以回收沼气再生能源的新课题。In order to solve this problem, a standard announcement number of DB43/T139-1999 introduced "Standard Atlas of Domestic Sewage Purification Digester" and a patent announcement number of CN2275579Y introduced "Efficient Energy-Free Domestic Sewage Treatment Device". The structure and process of the two are basically the same, both are anaerobic pretreatment and aerobic posttreatment. It is a relatively advanced biochemical treatment device in China at present. The purified sewage can meet the discharge standards. However, due to the use of traditional hydraulic mechanisms and soft Packing and hard filter material devices, so the long-term effect of treatment is generally poor, the efficiency is not high, and the discharge and management are difficult. The difference is that the former shows people a new topic that can recover biogas renewable energy in low-concentration domestic sewage .

采用了这样的结构后，设置的上流式池型机构，浮渣SS和超过极限所积压的沼气可通过上面大口经出料竖管排出和溢出池外，沉于底层的CO2、H2S等有毒气体可随空池时对流的空气排出池外，不但保护了池身和人身的安全，而且解决了浮渣SS出料难、产气率、病虫卵的沉降率、沼气池的寿命率低的问题；设置的半软填料机构，解决了填料因生物膜负荷加重后垂落，需反弹重复使用和上下牵挂于活动支架上的填料，因沼气气泡和悬浮物SS上浮，要其摆动但不互相打结的问题；在一级厌氧池进料管处的地面污泥脱水回收池内设置的污泥脱水滤篓，除满足污泥脱水过滤的要求外，其滤液中含有大量的菌种，利用菌种回流技术，达到了大幅度提高CH4的产气量和COD、BOD去除率的目的；设置的大口径出料竖管，除了方便插入污泥泵的抽肥管和悬浮物SS排出池外以外，还可插入取样管和扫描管及扫描器，确保大、中型厌氧池运行状况实现自动验测和电脑监护，管理非常方便；在机动脱水的沼渣污泥饼回收池内设置的吸附式污泥脱水机，使污泥经吸附，对滚挤压及渣水分流、刮刀挤刮，泥饼回收，四道工序周而复始连续作业而成，解决了沉积的粘稠性污泥脱水困难和连续脱水回收的问题；净化水不含重金属盐类，不但可满足生活用非饮用水和工业用软水的需要，而且只要稍作处理就可达到饮用水标准；装置的规模可大可小，小到集装箱型，可与建筑相连，也可根据地形远离建筑群，平面布局可因地自宜，既可单列，也可前、后处理分开并列，回收的再生资源可直接使用，但不是精品，所以仍需深加工：沼气脱硫，精品生态肥及包装，净化水加工为饮用水。After adopting such a structure, the upflow pool type mechanism is set, the scum SS and the biogas accumulated beyond the limit can be discharged through the upper big mouth through the discharge standpipe and overflow the pool, and the CO 2 and H 2 S that sink to the bottom Such toxic gases can be discharged out of the pool with the convective air when the pool is empty, which not only protects the safety of the pool body and people, but also solves the difficulty of scum SS discharge, gas production rate, sedimentation rate of diseased eggs, and the life of the biogas tank. The problem of low efficiency; the set semi-soft packing mechanism solves the problem that the packing hangs down due to the aggravation of the biofilm load, and the packing that needs to rebound and be reused and hangs up and down on the movable support. The problem of not knotting each other; the sludge dewatering filter basket installed in the ground sludge dehydration recovery tank at the feed pipe of the primary anaerobic tank, in addition to meeting the requirements of sludge dehydration and filtration, its filtrate contains a large number of bacterial species , using the strain backflow technology, the purpose of greatly increasing the gas production of CH 4 and the removal rate of COD and BOD is achieved; the large-diameter discharge vertical pipe is set, in addition to the convenience of inserting the fertilizer pipe of the sludge pump and the discharge of suspended solids SS Outside the tank, sampling tubes, scanning tubes and scanners can also be inserted to ensure that the operation status of large and medium-sized anaerobic tanks can be automatically checked and monitored by computer, and the management is very convenient; Adsorption sludge dewatering machine, through adsorption, rolling extrusion, slag water separation, scraper extrusion and scraping, mud cake recovery, the four processes are repeated and continuous operation, which solves the difficulty of dehydrating the deposited viscous sludge And the problem of continuous dehydration recovery; purified water does not contain heavy metal salts, not only can meet the needs of domestic non-drinking water and industrial soft water, but also can meet drinking water standards with a little treatment; the scale of the device can be large or small, As small as a container type, it can be connected to the building, or it can be far away from the building group according to the terrain. The layout can be adapted to the site, either in a single row, or in parallel before and after treatment. The recovered renewable resources can be used directly, but it is not a high-quality product. , so deep processing is still needed: biogas desulfurization, high-quality ecological fertilizer and packaging, purified water processing into drinking water.
