江苏水处理生活废水处理电解式哪家好

江苏常州水处理

（一）污水处理技术路线

农村污水处理技术的选择要量力而行，充分考虑到农村地区财力状况薄弱、农民实际承受能力较低这一普遍情况，处理工艺的选择不能盲目攀比，不能一味地选择时髦、处理效果好、自动化控制水平很高的处理工艺，而着重应该考虑选用既成熟可靠，又适合农村特点和实际的污水处理适用技术。建议污水处理技术的选择达到两个目标：一是达标排放或回用；二是注重经济适用，运行成本低，管理维护简单。

目前国内外应用农村生活污水处理设备的处理技术比较多，名称也多种多样，但从工艺原理上通常可归为两类：类是自然处理系统。利用土壤过滤、植物吸收和微生物分解的原理，又称为生态处理系统。第二类是生物处理系统，又可分为好氧生物处理和厌氧生物处理。好氧生物处理是通过动力给污水充氧，培养微生物菌种，利用微生物菌种分解、消耗吸收污水中的有机物、氮和磷。厌氧生物处理是利用厌氧微生物的代谢过程，在无需提供氧气的情况下把有机污染物转化为无机物和少量的细胞物质。

（二）人工湿地处理系统

有条件的村庄，应充分利用现有的农田灌排渠道与附近的荒地、废塘、洼地和沼泽地等，建设人工湿地处理系统。

污水湿地处理系统分自然和人工湿地处理系统，自然湿地就是自然的沼泽地，人工湿地污水处理技术是一种基于自然生态原理，使污水处理达到工程化、实用化的新技术。将污水有控制地投配到土壤经常处于饱和状态、生长有象芦苇、香蒲等沼泽生植物的土地上，利用植物根系的吸收和微生物的作用，并经过多层过滤，来达到降解污染、净化水质的目的，它是一种充分利用地下人工介质中栖息的植物、微生物、植物根系， 以及介质所具有的物理、化学特性，将污水净化的天然与人工处理相结合的复合工艺。

湿地处理系统工艺设备简单、运转维护管理方便、能耗低、工程基建低、运行费用低、对进水负荷的适应性强，能耐受冲击负荷，净化出水水质良好、稳定。缺点占地面积大，易受气候影响，表面径流的臭味比较大。

（三）地下土壤渗滤净化系统

分散的几户或十几户人家适合采用地下土壤渗滤净化系统。

地下土壤渗滤净化系统是一种基于自然生态原理，予以工程化、实用化而创造出的一种新型小规模污水净化工艺技术，是将污水有控制地投配到经一定构造、距地面约50 cm深和具有良好扩散性能的土层中。投配污水缓慢通过布水管周围的碎石和砂层，在土壤毛管作用下向附近土层中扩散。表层土壤中有大量微生物，作物根区处于好氧状态，污水中的污染物质被过滤、吸附、降解。所以地下渗滤的处理过程非常类似于污水慢速渗滤处理过程。由于负荷低，停留时间长，水质净化效果非常好，而且稳定。地下土壤渗滤净化系统建设容易、维护管理简单，基建投资少，运行费用低。整个处理装置放在地下，不损害景观，不产生臭气。

（四）好氧生物处理系统

生活污水处理设备好氧生物处理系统是新农村污水处理中常用的一种处理技术。好氧生物处理工艺众多，各有优缺点，选择时要根据实际情况仔细论证和比选，注重经济适用。

生物处理法就是通过风机等设备给污水输氧，培养生物菌种和微生物，通过菌种和微生物把污水中的大部分有机物分解为的二氧化碳、水等物质，少部分合成为细胞物质，促使微生物增长，并以剩余污泥的形式排出，使污水得以净化排放。如SBR法，集曝气、沉淀、排水功能于一体，不断地转换，省去了传统的污泥回流设备，大大降低了建设费用；A20法具有脱氮、除磷功能，还有如生物转盘处理工艺、膜生物反应器处理工艺等。生物处理法和自然处理系统比较， 占地面积小，抗气候等外界影响的能力强，建设的地点选择范围大，处理稳定，处理。但基建投资、运行成本要自然处理系统。

（五）厌氧生物处理系统

我国从上个世纪80年代开始开展生活污水厌氧生物法的开发和研制工作，许多形式各异的无动力或微动力的低能耗型一体化污水处理装置得到应用。如无动力地埋式生活污水处理设备采用无动力厌氧生物膜技术，工艺流程简单，不耗能，全部埋于地下，也无需专人管理。与好氧生物处理相比，无动力地埋式生活污水处理装置技术设备的基建投资略好氧处理，无日常运行费用的支出。

厌氧生物法目前技术上还存在一些问题，主要表现在生物处理效率较低，尤其表现为氮磷去除率很低，在一定程度上限制了其应用。

Water treatment in Changzhou, Jiangsu

(1) technical route of sewage treatment

Selection of technology for treating rural sewage to be doing, give full consideration to the financial situation in rural areas is weak, the actual bearing capacity is low in the general situation, not blindly choose treatment process, can not blindly choose fashionable process advanced, good treatment effect, the automation level is high, and the emphasis should consider to choose both mature and reliable, and suitable for the rural characteristics and actual sewage treatment technology. It is suggested that the choice of sewage treatment technology should achieve two goals: first, discharge or reuse to the standard; two, pay attention to economic application, low operation cost and simple management and maintenance.

At present, there are many technologies dealing with rural domestic sewage treatment equipment at home and abroad, but there are various names. But from the technological principle, they can usually be classified into two categories: the first is natural treatment system. The principle of soil filtration, plant absorption and microbial decomposition is also called ecological treatment system. The second is the biological treatment system, which can be divided into aerobic biological treatment and anaerobic biological treatment. Aerobic biological treatment is through power to oxygenate sewage, cultivate microbial strains, use microbial strains to decompose, consume and absorb organic matter, nitrogen and phosphorus in sewage. Anaerobic biological treatment is based on the metabolic process of anaerobic microorganism. It can transform organic pollutants into inorganic substances and a small amount of cell substances without providing oxygen.

(two) artificial wetland treatment system

The conditions of the village, should make full use of existing farmland irrigation and drainage channels and nearby wasteland, waste ponds, depressions and swamp, construction of artificial wetland treatment system.

Sewage wetland treatment system is divided into natural and artificial wetland treatment system. Natural wetlands are natural marshes. Constructed wetland wastewater treatment technology is a new technology based on natural ecological principles, which makes sewage treatment engineering and practical. The sewage control dosing to soil are often saturated, growth like reeds, cattails and other marsh plants on land use, plant uptake and microbial root function, and through the multilayer filter, to achieve the purpose of purifying water quality, pollution degradation, it is a kind of artificial media and make full use of underground habitat plants and microorganisms, plant roots, and the physical medium, has the chemical properties, composite technology of natural and artificial processing sewage purification combined.

The wetland treatment system has the advantages of simple process equipment, convenient operation and maintenance management, low energy consumption, low engineering infrastructure, low operation cost, strong adaptability to the influent load, and can withstand the impact load. The purified effluent quality is good and stable. The defects are large, easy to be affected by the climate, and the odor of surface runoff is relatively large.

(three) underground soil percolation and purification system

Several scattered households or more than a dozen households are suitable for the use of underground soil filtration and purification systems.

The underground soil filtration system is a natural ecological principle based on the practical engineering, to create a new technology for small-scale sewage purification, sewage is controlled by certain dosing to construct, from the ground about 50 cm deep and has good diffusion properties in soil. The sewage was slowly passed through the gravel and sand layer around the pipe, and spread to the nearby soil layer under the action of soil capillary. There are a lot of microbes in the surface soil, and the root zone of the crop is in the aerobic state, and the polluted material in the sewage is filtered, adsorbed and degraded. So the process of subterranean filtration is very similar to the slow filtration process of sewage. Because of low load and long stay time, the effect of water purification is very good and stable. Underground soil filtration and purification system is easy to build, simple maintenance and management, low investment in infrastructure and low operating cost. The whole treatment device is placed in the ground without damage to the landscape and no odor.

(four) aerobic biological treatment system

The aerobic biological treatment system of domestic sewage treatment equipment is one of the most commonly used treatment techniques in the new rural sewage treatment. The aerobic biological treatment process has many advantages and disadvantages, and should be carefully demonstrated and selected in accordance with the actual situation, and pay attention to the economic application.

Biological treatment method for wastewater is oxygen through the fan and other equipment, training of biological bacteria and microorganisms, bacteria and microorganisms through most of the organic matter in the sewage is decomposed into carbon dioxide and water substances such as no pollution, few for the synthesis of cellular material, promote microbial growth, and the remaining sludge is discharged, so that sewage can be purified discharge. Such as SBR method, set aeration, precipitation, drainage functions, continuous conversion, eliminating the traditional sludge reflux device, greatly reduces the construction cost; with nitrogen and phosphorus by A20, as well as the biological treatment process, membrane bioreactor process etc.. Compared with the natural treatment system, the biological treatment and the natural treatment system have the advantages of small footprint, strong ability to resist external influences such as climate and so on. The location of the construction is large, the treatment is stable, and the treatment efficiency is high. But the investment and operation cost of capital construction should be higher than that of the natural processing system.

(five) anaerobic biological treatment system

Since 80s of last century, our country began to develop and develop the anaerobic biological process of domestic sewage. Many different forms of low power and energy consumption integrated sewage treatment devices without power or micro power have been applied. For example, the unpowered buried sewage treatment equipment adopts the anaerobic anaerobic biofilm technology. The process is simple, and the energy consumption is not buried, and there is no need for personal management. Compared with aerobic biological treatment, the infrastructure investment of the power plant sewage treatment plant is slightly higher than that of aerobic treatment, and there is no daily operation cost.
