(1) The margin of life is long, the treatment effect is good, and BOD5 and turbidity are low. (such as small bell worm, eight clock worm, gouth worm, nymphal worm, bottle of worm, micro-caged worm, cockroach) These types of bristles are fixed on the floc and flipped with the window It also contains some crawling habitats, worms, pointed caterpillars, and worms, which indicate high-quality and mature activated sludge.
(2) Small worms are often the dominant species in the treatment of domestic sewage and industrial wastewater.
(3) If a large number of flagellates appear, and the margins of the living are few, the purification is poor.
(4) A large number of free-flowing ciliates appear, indicating that the purification is not good and the turbidity of the effluent rises.
(5) If there are major ciliates, such as bell worms, worms, cover worms, rotifers, and oligochaetes, the water quality is clear, the effluent is clear and transparent, and the phenol removal rate is above 90%.
(6) The emergence of a large number of root-footed worms is often a manifestation of sludge poisoning.
(7) In the case of domestic sewage treatment, the presence of a large number of worms is a sign of sludge swelling and deflocculating.
(8) In the printing and dyeing wastewater, the larvae are used as indicator organisms for normal or improved sludge.
(9) The emergence of worms in petroleum wastewater treatment is an ideal effect.
(10) Excessive rotifers appear as a sign of sludge swelling.
In addition, in some sludges that are not suitable for growth of protozoa, the size of the micelles is mainly used to judge the treatment effect. Amoeba (Amoeba) amoeba.
As the name suggests, amoeba can be deformed. However, this deformation is also limited. Some types of amoeba can extend the prosthetic foot out of the four to explore the chemical composition of the water and determine the direction of movement. And some types have no fake feet at all. When they hunt, they cover their prey and wrap their prey, which creates a food bubble that can absorb prey. Most amoeba are harmless to the human body, but several amoeba can produce human diseases: amoebic dysentery, mainly in poor countries. Amoeba has a wide range of foods, single-cell algae, bacteria, small protozoa, fungi, organic debris, etc. are all their food. Amoeba has strong vitality, and when conditions are not good, it can form a cyst (sleep) to tide over the difficulties.
