答：不能。

　　水處理藥劑(也稱作水處理劑、水處理化學品，Water Treatment Chemicals)是工業用水、生活用水、廢水處置過程中通常所需的化學藥劑。

　　主要作用是控制水垢、污泥的形成，減少與水接觸的材料的腐蝕，除去水中的懸浮固體和有毒物質，除臭脫色，軟化和穩定水質等。

　　水處理藥劑廣泛應用于化工、石油、輕工、日化、紡織、印染、 建筑、冶金、機械、醫藥衛生、交通、城鄉環保等行業，包括廢水和污水處理、冷卻水和鍋爐水的處理、海水和苦咸水淡化、膜分離、生物處理、絮凝和離子交換等技術所需的藥劑。

　　通常根據產品性能，水處理藥劑可分為絮凝劑、阻垢劑、緩蝕劑、殺菌劑、消泡劑、清洗劑等。此外，還可劃分為一般水處理化學品和專用水處理化學品，一般水處理化學品如明礬、氯、硫酸鐵、 三氯化鐵和聚合氯化鋁等;專用水處理化學品又分為單一化學品 (如**絮凝劑)和配方產品(殺菌劑、防腐劑和阻垢劑等)。

　　通過上文我們了解了水處理藥劑的應用范圍與分類，下面來講一下水處理在天然水體中的優缺點！采用水處理藥品法治理天然水體**的優勢是效果快，能夠在短時間內實現水體潔凈清澈的效果!但更為嚴重的影響是將打破原先天然水體的生態系統，使水體的自凈作用喪失殆盡。甚至有些化學藥劑在投放后馬上出現大量的死魚，使原先河道中的生物被徹底的殺滅就是明證。（以上關于水處理藥劑的介紹來源于百度百科，并非本廠小編自撰！）

　　在采用化學法治理污水時，是將化學污泥通過沉淀濃縮或絮凝后再予以妥善的處理處置，但處置的同時也需要安裝一些曝氣增氧設備配合使用!后期弱項維持水生態的平衡，需要長期的添加藥劑，大量的藥劑購買會使后期成本居高不下!那么有沒有什么可以不添加藥劑進行水生態修復的方法呢?

　　有的!

這個方法就是微孔曝氣增氧技術!

微孔曝氣增氧技術是繼水車式、葉輪式、噴泉式傳統增氧技術之后的新型增氧技術，已被水產養殖、污水處理、景觀水治理領域廣泛應用。微孔曝氣增氧裝置，安裝方便，安全可靠，沒有電源的養殖場，可選擇柴油機為動力。是綜合了先進示范運行和測試數據，以及有關資料的新型養殖技術。

該方法可利用我廠生產銷售的沉水風機與羅茨風機作為氣體輸送來源，與微孔曝氣盤結合!實現水體底部曝氣增氧!將上層溶氧率高的水流與底部溶氧率低的水體進行混合!充分提高水體溶氧率!降低水體氨氮含量!水體氧含量高了會促進水體原有微生物的繁殖與存活!在后期的水生態治理中，僅僅需要交納沉水風機的電費即可!相比于化學藥劑的成本要低很多!具體的優勢如下：

　　高效增氧

　　微孔曝氣產生的微小氣泡在水體中與水的接觸面極大，上浮流速低，接觸時間長，氧的傳質效率極高。

　　增氧成本低

　　采用微孔增氧裝置，氧的傳質效率極高，能使水體溶氧迅速增高，其能耗不到傳統增氧裝置的四分之一，可大大節約電(柴油)費的成本支出。如配置功率為2.2KW微孔曝氣增氧裝置，可保證8-15畝精養池塘或者1000-2000平方米投餌網箱應急增氧所需。

　　活化水體

　　由于微孔曝氣管(盤)安裝在池塘1.0-3.0M水深的池底部或者懸掛在3.0-4.0M水深的網箱底部微小而緩慢上升的氣泡流猶如將水體變成一條緩緩流動的河流，使表層水體和底層水體同時均勻增氧。充足的溶氧可加速水體底層沉積的肥泥、散落和剩余編制的餌料以及魚類排泄物等**質的分解，轉化為微生物，使水體自我凈化功能得以恢復，建立起自然水體生態系統，使水活起來。

　　實現生態養殖、保障養殖效益

　　持續不斷的微孔曝氣增氧，水體自我凈化能力得以恢復**，菌相、藻相自然平衡，構建起水體的自然生態，養殖種群的生存能力穩定提高，充分保障養殖效益。

　　安全性、環保性能高

　　微孔曝氣增氧裝置安裝在陸地或養殖漁排上，安全性能好，不會給水體帶來任何污染，而其他微孔增氧裝置在水中工作，容易漏電，對人和魚蝦有潛在危害。

以上便是為什么城鎮河道水生態治理不可選用水處理藥劑的原因！

　　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!
