鱼缸水质跌酸是怎么回事?

 发布时间:2018-03-06 15:43:39 浏览次数:200

为何鱼缸会跌酸,跌酸后怎么处理?我们常用的生化滤材大体分两种,粘合滤材和烧结滤材。
Why can the fish bowl fall acid and how to deal with the acid after falling acid? We commonly use two kinds of biochemical filter materials, adhesive material and sintered filter.
粘合滤材以晓滤和中空滤材为代表,曾经盛行一时的no.1似乎因为假货太多已退出了历史舞台。烧结滤材以陶瓷环、细菌屋、陶瓷球为代表,也已经逐渐被大神们抛弃,唯一选择的理由也就是价低,可以配合使用而已。
With the filter and hollow filter as the representative, the once popular No.1 seems to be out of the historical stage because of too many fake goods. Sintered filter to ceramic ring, ceramic balls, bacteria house as a representative, has gradually been abandoned people, the only choice of reason is low, can be used in conjunction.
发生跌酸的原因有两种,一种是对水质不管不顾,恶化导致的,第二种是太过于担心硝化系统的建立,而主动添加了太多的硝化细菌导致的。
There are two reasons for the occurrence of acid fell, one is on the water quality deterioration due to be careless with, and the second is too worried about establishment of nitrification system, and take the initiative to add too much to the nitrifying bacteria.
前者主要发生在烧结滤材上,因为这种滤材大多使用寿命短,半年不到其实就已经华而不实,内忧外患。烧结滤材使用的主要材料是“高岭土”,成分是二氧化硅、氧化铝,制作工艺与陶瓷类似,运用发泡工艺,孔隙率最高可做到60%以上,使用广泛,相对安全。弊端在于其内部微孔密集,纵横交错,一旦表面污染,微孔极容易堵塞,内部通道就形同虚设,只有表面的一层可供硝化细菌附着。而被堵塞在里面的硝化细菌,因长期缺氧死亡,细菌分解尸体产生大量酸性物质,导致水体跌酸。
The former mainly occurs in the sintered filter, because the filter most of short service life, less than half a year in fact already flashy without substance, domestic trouble and foreign invasion. The main material used for sintered filter material is kaolin. Its composition is silica and alumina. The manufacturing process is similar to that of ceramics. With the foaming technology, the porosity can reach over 60%, which is widely used and relatively safe. The disadvantage is that its internal micropores are dense and crisscrossed. Once the surface is polluted, the micropores are easily blocked, and the internal passages are virtually useless. Only the surface layer can be attached to nitrifying bacteria. The nitrifying bacteria, which are clogged in the inside, are killed by a long period of hypoxia, and the bacteria decompose the corpse to produce a large amount of acid, causing the water to fall acid.


粘合滤材相对于烧结滤材更持久,更透水透气,但也会有突然跌酸的窘态,是为什么呢?很多鱼友在第一次尝试使用这种滤材时,出于硝化细菌繁殖周期长的担心,在水中倒入了过多的人工硝化细菌。其实有所不知,硝化系统过犹不及。
The adhesive filter relative to the sintered filter more durable, more permeable, but it also has suddenly dropped acid embarrassment, why? Many fish friends in the first attempt to use this kind of filter, because of the long fear of nitrifying bacteria breeding cycle, in the water into a lot of artificial nitrifying bacteria. In fact, I do not know, nitrification system too far.
氨在水中有两种形态,即氨(NH3)和铵(NH4+),二者浓度之和称为总氨量,氨有毒,铵无毒。氨受水中PH影响会有微妙变化,PH<7时,氨就不会产生,所以鱼就是安全的,当PH>7时,PH越高,氨的含量就越高,鱼的危险就越大。虽然铵无毒,但在PH影响下也会转化为氨,所以将氨和铵都转化掉,就是硝化细菌的使命。根据换水量和饲养密度,硝化系统存在一个平衡值,即总氨量为0,在已经达到这个指标的基础上如果硝化细菌过多,硝化反应的速度就会加快,所产生的硝酸就会加重水中的酸度,而且是急剧下降,换水都只能解燃眉之急。
There are two forms of ammonia in water, namely, ammonia (NH3) and ammonium (NH4+). The sum of the two concentration is called total ammonia, ammonia is toxic and ammonium is nontoxic. Ammonia is affected by PH in water. There will be subtle changes. When PH < 7, ammonia will not happen, so fish is safe. When PH > 7, the higher the PH is, the higher the content of ammonia is, and the greater the risk of fish. Although ammonium is nontoxic, it can also be converted into ammonia under the influence of PH, so it is the mission of nitrifying bacteria to convert ammonia and ammonium. According to the change of water content and feeding density, there is a balance value nitrification system, i.e. total amount of ammonia was 0, based on this index has reached the nitrifying bacteria if too much, will accelerate the speed of nitrification, produced by nitric acid will increase the acidity of water, and a sharp decline in water solution as pressing danger only.
