答：不能。

　　水处理药剂(也称作水处理剂、水处理化学品，Water Treatment Chemicals)是工业用水、生活用水、废水处置过程中通常所需的化学药剂。

　　主要作用是控制水垢、污泥的形成，减少与水接触的材料的腐蚀，除去水中的悬浮固体和有毒物质，除臭脱色，软化和稳定水质等。

　　水处理药剂广泛应用于化工、石油、轻工、日化、纺织、印染、 建筑、冶金、机械、医药卫生、交通、城乡环保等行业，包括废水和污水处理、冷却水和锅炉水的处理、海水和苦咸水淡化、膜分离、生物处理、絮凝和离子交换等技术所需的药剂。

　　通常根据产品性能，水处理药剂可分为絮凝剂、阻垢剂、缓蚀剂、杀菌剂、消泡剂、清洗剂等。此外，还可划分为一般水处理化学品和专用水处理化学品，一般水处理化学品如明矾、氯、硫酸铁、 三氯化铁和聚合氯化铝等;专用水处理化学品又分为单一化学品 (如**絮凝剂)和配方产品(杀菌剂、防腐剂和阻垢剂等)。

　　通过上文我们了解了水处理药剂的应用范围与分类，下面来讲一下水处理在天然水体中的优缺点！采用水处理药品法治理天然水体**的优势是效果快，能够在短时间内实现水体洁净清澈的效果!但更为严重的影响是将打破原先天然水体的生态系统，使水体的自净作用丧失殆尽。甚至有些化学药剂在投放后马上出现大量的死鱼，使原先河道中的生物被彻底的杀灭就是明证。（以上关于水处理药剂的介绍来源于百度百科，并非本厂小编自撰！）

　　在采用化学法治理污水时，是将化学污泥通过沉淀浓缩或絮凝后再予以妥善的处理处置，但处置的同时也需要安装一些曝气增氧设备配合使用!后期弱项维持水生态的平衡，需要长期的添加药剂，大量的药剂购买会使后期成本居高不下!那么有没有什么可以不添加药剂进行水生态修复的方法呢?

　　有的!

这个方法就是微孔曝气增氧技术!

微孔曝气增氧技术是继水车式、叶轮式、喷泉式传统增氧技术之后的新型增氧技术，已被水产养殖、污水处理、景观水治理领域广泛应用。微孔曝气增氧装置，安装方便，安全可靠，没有电源的养殖场，可选择柴油机为动力。是综合了先进示范运行和测试数据，以及有关资料的新型养殖技术。

该方法可利用我厂生产销售的沉水风机与罗茨风机作为气体输送来源，与微孔曝气盘结合!实现水体底部曝气增氧!将上层溶氧率高的水流与底部溶氧率低的水体进行混合!充分提高水体溶氧率!降低水体氨氮含量!水体氧含量高了会促进水体原有微生物的繁殖与存活!在后期的水生态治理中，仅仅需要交纳沉水风机的电费即可!相比于化学药剂的成本要低很多!具体的优势如下：

　　高效增氧

　　微孔曝气产生的微小气泡在水体中与水的接触面极大，上浮流速低，接触时间长，氧的传质效率极高。

　　增氧成本低

　　采用微孔增氧装置，氧的传质效率极高，能使水体溶氧迅速增高，其能耗不到传统增氧装置的四分之一，可大大节约电(柴油)费的成本支出。如配置功率为2.2KW微孔曝气增氧装置，可保证8-15亩精养池塘或者1000-2000平方米投饵网箱应急增氧所需。

　　活化水体

　　由于微孔曝气管(盘)安装在池塘1.0-3.0M水深的池底部或者悬挂在3.0-4.0M水深的网箱底部微小而缓慢上升的气泡流犹如将水体变成一条缓缓流动的河流，使表层水体和底层水体同时均匀增氧。充足的溶氧可加速水体底层沉积的肥泥、散落和剩余编制的饵料以及鱼类排泄物等**质的分解，转化为微生物，使水体自我净化功能得以恢复，建立起自然水体生态系统，使水活起来。

　　实现生态养殖、保障养殖效益

　　持续不断的微孔曝气增氧，水体自我净化能力得以恢复**，菌相、藻相自然平衡，构建起水体的自然生态，养殖种群的生存能力稳定提高，充分保障养殖效益。

　　安全性、环保性能高

　　微孔曝气增氧装置安装在陆地或养殖渔排上，安全性能好，不会给水体带来任何污染，而其他微孔增氧装置在水中工作，容易漏电，对人和鱼虾有潜在危害。

以上便是为什么城镇河道水生态治理不可选用水处理药剂的原因！

　　A: No.

　　Water treatment chemicals (also known as water treatment agents, water treatment chemicals) are commonly used in the treatment of industrial water, domestic water and wastewater.

　　Its main function is to control the formation of scale and sludge, reduce the corrosion of materials in contact with water, remove suspended solids and toxic substances in water, deodorize and decolorize, soften and stabilize water quality, etc.

　　Water treatment agents are widely used in chemical, petroleum, light industry, daily chemical, textile, printing and dyeing, construction, metallurgy, machinery, medicine and health, transportation, urban and rural environmental protection and other industries, including chemicals required for wastewater and sewage treatment, cooling water and boiler water treatment, seawater and brackish water desalination, membrane separation, biological treatment, flocculation, ion exchange and other technologies.

　　Generally, according to the product performance, water treatment agents can be divided into flocculants, scale inhibitors, corrosion inhibitors, fungicides, defoamers, cleaning agents, etc. In addition, it can also be divided into general water treatment chemicals and special water treatment chemicals. General water treatment chemicals such as alum, chlorine, ferric sulfate, ferric chloride and polyaluminum chloride; Special water treatment chemicals are divided into single chemicals (such as organic flocculants) and formula products (fungicides, preservatives, scale inhibitors, etc.).

　　From the above, we know the application scope and classification of water treatment agents. Next, let's talk about the advantages and disadvantages of primary water treatment in natural water bodies! The only advantage of using water treatment drugs to treat natural water bodies is that the effect is fast, and it can achieve the effect of clean and clear water bodies in a short time! But the more serious impact is that it will break the ecosystem of the original natural water body and make the self purification of the water body completely lost. Even a large number of dead fish appear immediately after the release of some chemicals, which is clear evidence that the organisms in the original river were completely killed. (the above introduction about water treatment chemicals is from Baidu Encyclopedia, not written by our factory!)

　　When the chemical method is used to treat sewage, the chemical sludge is properly treated and disposed after sedimentation, concentration or flocculation, but at the same time, some aeration and oxygenation equipment need to be installed for use! Maintaining the balance of water ecology in the later stage requires long-term addition of chemicals, and a large number of drug purchases will keep the cost high in the later stage! Is there any way to restore the aquatic ecosystem without adding chemicals?

　　Can chemical water treatment agents be used in the treatment of urban river water pollution

　　yes , we have!

　　This method is microporous aeration technology!

　　Microporous aeration oxygenation technology is a new type of oxygenation technology after the traditional oxygenation technology of waterwheel, impeller and fountain. It has been widely used in aquaculture, sewage treatment and landscape water treatment. Microporous aeration aerator is easy to install, safe and reliable. For farms without power supply, diesel engines can be used as power. It is a new breeding technology that integrates advanced demonstration operation and test data, as well as relevant information.

　　This method can use the submerged fan and Roots fan produced and sold by our factory as the gas transmission source, and combine with the microporous aeration disk! Realize aeration and oxygenation at the bottom of water body! Mix the water with high dissolved oxygen rate in the upper layer with the water with low dissolved oxygen rate at the bottom! Fully improve the dissolved oxygen rate of water! Reduce ammonia nitrogen content in water! High oxygen content in water will promote the reproduction and survival of original microorganisms in water! In the later stage of water ecological treatment, you only need to pay the electricity charge of submerged fan! Compared with chemical agents, the cost is much lower! Specific advantages are as follows:

　　High efficiency oxygenation

　　The tiny bubbles produced by microporous aeration have a large contact surface with water in the water body, low floating velocity, long contact time, and high oxygen mass transfer efficiency.

　　Low oxygenation cost

　　Using microporous oxygenation device, the mass transfer efficiency of oxygen is very high, which can rapidly increase the dissolved oxygen in water, and its energy consumption is less than a quarter of that of traditional oxygenation device, which can greatly save the cost of electricity (diesel) fees. If equipped with a 2.2kW microporous aeration and oxygenation device, it can ensure the emergency oxygenation of 8-15 Mu intensive culture pond or 1000-2000 square meters of feeding cage.

　　Activate water body

　　Since the microporous aeration pipe (disc) is installed at the bottom of the pond with a water depth of 1.0-3.0m or suspended at the bottom of the cage with a water depth of 3.0-4.0m, the tiny and slowly rising bubble flow is like turning the water body into a slowly flowing river, making the surface water body and the bottom water body increase oxygen evenly at the same time. Sufficient dissolved oxygen can accelerate the decomposition of organic matter such as fertilizer sludge, scattered and residual bait and fish excreta deposited at the bottom of the water body, and convert them into microorganisms, so that the self purification function of the water body can be restored, and a natural water ecosystem can be established to make the water live.

　　Realize ecological breeding and ensure breeding benefits

　　Continuous microporous aeration and oxygenation can restore and improve the self purification ability of the water body, and the natural balance of bacterial phase and algal phase can build the natural ecology of the water body, and the viability of the breeding population can be improved stably to fully ensure the breeding benefits.

　　High safety and environmental performance

　　The microporous aeration and oxygenation device is installed on land or aquaculture rafts, which has good safety performance and will not bring any pollution to the water body. While other microporous aeration devices work in water, which are easy to leak electricity and have potential hazards to people, fish and shrimp.

　　The above is the reason why water treatment agents cannot be selected for urban river water ecological treatment!
