In order to prevent the growth of algae in artificial swimming pools, how should the pool water be treated? What should be done after algae is discovered?

1. 1. Why is the pool water blue?

This is because copper sulfate, sodium hypochlorite and alum are used at the appropriate time, so the water quality is relatively clear. At the same time, the water is blue. About 1 kilogram is placed in 1000 cubic meters. The copper ions are blue, so it looks blue.

Copper sulfate is mainly used to kill algae and remove algae from swimming pools. Sodium hypochlorite is mainly used for disinfection. Alum mainly plays a precipitating role. There are two main ways to keep water clean. The first is to use a drug pump. Automatic dosing and then manual spraying. If there is sediment, conduct underwater dust removal in time until the water quality reaches the standard.

The water in the swimming pool is blue because chemicals are added to the water. Adding chemicals is also for disinfection

To put it simply:

1. Copper sulfate should be put into the swimming pool. It is about 1 kilogram in 1000 cubic meters. The copper ions are blue, so you can see It looks blue.

2 But not every swimming pool looks blue. Copper sulfate is mainly used for its algae removal function. However, some swimming pools have less algae, so there is very little copper sulfate, which is decomposed from bleaching powder. Chloride is a bit green, and the surrounding trees, so some swimming pools look a bit green, but very light green.

3 To correct the above statement, sodium hypochlorite has a disinfecting effect, chloride ions are greenish, and sodium hypochlorite and alum will not make the water blue. There is still only one blue color: copper sulfate.

2. Why are there waves in the pool water?

The swimming pool itself has no waves, but when you swim too hard in a swimming pool with high buoyancy, there will be some small waves (may not be considered as waves) It's a wave, right?

3. Will pool water spread diseases?

Patients with infectious diseases such as trachoma, otitis media, and skin diseases may cause trouble to others.

Disease transmission in swimming pools

A 15-year-old girl contracted non-gonococcal urethritis after renting a swimsuit from a swimming pool; and another male patient contracted non-gonococcal urethritis due to fatigue from swimming. He contracted gonorrhea while relaxing by the pool. Can you get STDs from swimming? Generally speaking, you will not get sexually transmitted diseases while swimming. However, if swimming pool disinfection management is not strict, there is also the possibility of infection with gonorrhea or urethritis. It is not uncommon for urethritis to be caused by water-borne infections. Gonorrhea is an infectious disease that is mainly transmitted through sexual intercourse. However, if a gonorrhea patient goes swimming and pollutes the water source, it can also cause gonococcal conjunctivitis in others. It is an acute purulent conjunctivitis disease that usually begins more than 10 hours or 2-3 days after infection. It occurs in both eyes or one eye. The eyelids are highly edematous, red, swollen, and painful. If you do a conjunctival epithelial scraping, you can Large numbers of gonococci were found. The discharge is bloody or serous, and no bacteria can be found. After 5 days, the swelling reduced and became soft, but a large amount of purulent secretions overflowed from the palpebral fissures. The secretions at this time may contain a large number of lymphocytes. After about 2-3 weeks, the purulent secretions will decrease and the edema will subside. Because the conjunctiva involves the cornea, it often causes corneal complications, ulcers, and can lead to perforation and blindness.

Chlamydia infection, which is common among sexually transmitted diseases, can also be transmitted through swimming pools. After the patient enters the swimming pool, it can cause chlamydial urethritis in other swimmers. It can also infect the eyes and cause inclusion conjunctivitis (also known as swimming pool conjunctivitis). Symptoms usually appear 8-14 days after swimming in contaminated water. Eyelid edema begins, and the conjunctiva is highly congested. There is more secretion in the early stage. Occasionally, slight pseudomembrane may form. The lesions are mostly limited to one side. Preauricular lymph nodes are swollen and painful. The cornea is generally not affected, but occasionally it can be affected. , superficial punctate infiltration occurred, and inclusion bodies were visible on conjunctival scraping examination.

In addition, there are often hidden dangers beside the swimming pool. Multiple studies have revealed that sexually transmitted diseases do not necessarily have to be transmitted through sexual contact. Sexually transmitted diseases can also be transmitted through sexual clothing, towels, bathware, etc. In addition, germs may also be left where sexually transmitted diseases patients have sat. It is now known that Treponema pallidum can survive for several hours in damp utensils or wet towels, and Neisseria gonorrhoeae attached to clothes, pants and bedding can survive for 18-24 hours. Someone checked the bath towels, bathtubs, lockers, slippers and other items of gonorrhea patients after bathing and found gonococci. If healthy people come into contact with these contaminated items and places, especially when swimming with little clothing, it may Infection with sexually transmitted diseases.
