How to get rid of red sandworms in tap water

The redworms in the sink should be in the sink.

Users who use water tanks or other secondary water supply facilities (such as reservoirs) find that there are red worms in their tap water, mainly because the water tanks or other secondary water supply facilities are not cleaned in time and cause contamination, which is very easy to breed red nematodes.

The phenomenon of red nematodes found in the water by direct water supply users is due to the high temperature and high humidity in summer, which is suitable for the growth of red nematodes, and a large number of them survive in sewer ditches and pipelines. At night, they often crawl out of the sewer pipes and along the walls of the pool and water pipes into the outlet of the user's tap, merging into a clump. When users use water for the first time in the morning, they flush them out, creating the illusion that red threadworms are coming out of the tap water.

Secondary water supply facilities such as water tanks should be maintained, cleaned and disinfected in a timely manner to prevent the growth of red nematodes in the water.

Users should pay attention to the hygiene of the water environment, keep the tap water pool clean, try not to place brooms, rags and other wet objects next to the tap water pool at night, and plug the tap water pool drain with a plug.

Qualified users can also frequently disinfect the sewer pipes, and use boiling water to scald the tap water pool and the sewer pipes under the pool to prevent the nematodes from crawling outside.

Soak some vinegar and rub it on the rag with disinfectant water.

There is bleaching powder, with some disinfectant, bubble sterilization.

It is Daphnia, commonly known as bloodworms, which can generally be found in filter cotton.

Treatment and disinfection method: spraying 5% effective concentration of hydrogen peroxide (hydrogen peroxide) can kill bloodworms in a short time.

Due to poor management of benches, the reservoir has not been cleaned and disinfected for a long time or the cleaning and disinfection is not standardized, the bottom of the pond is muddy, the wall of the pond is dirty, and even moss breeds, this environment is suitable for bloodworm breeding and fostering, reproduction and reproduction.

Bloodworms are highly tolerant to the environment and reproduce rapidly, and are not easily killed by chlorine in tap water. Especially in the hot summer, the high temperature is easy to make the residual chlorine in the water volatilize faster, the disinfection ability is reduced, and the bloodworm is more likely to survive, so the frequency of bloodworm contamination of drinking water increases significantly in summer.

Disinfection steps After notifying the user, close the inlet and outlet valves of the water tank and pool.

Dissolve hydrogen peroxide or bleaching powder in a bucket first, then put it into the water tank or pool, and stir well.

Turn on the water from the faucet in the resident's home (or directly open the vent valve of the water tank and pool), and close the faucet (vent valve) after the chemical smell is released from the faucet (vent valve), and the time is generally maintained for more than 2 hours.

After maintaining the disinfection time for more than 2 hours, drain the water in the water tank, pool and pipes, and then pour clean water to wash until the water flowing from the faucet in the residents' homes has no chemical smell, and then it can be returned to normal use.

The presence of nematodes indicates that the tap water has been organically contaminated at some point during transportation. Explain how to prevent it:

1. Red nematodes.

Water earthworms, also known as red filariads and red nematodes, belong to the aquatic oligochaetes of annelids, with bright red or red flesh and orange-yellow body color. They mostly live in gutter sludge (usually slow-flowing black sludge) that discharges sewage or wastewater.

2. The location and cause of the red worm.

When red worms are found in tap water when the tap is turned on, water tanks or other secondary water supply facilities (e.g. cisterns) are found, the main reason is that the water tanks or other secondary water supply facilities are not cleaned in time due to contamination, resulting in red worm breeding.

The phenomenon of red nematodes in the water is found by the direct water supply users under the accompanying beam on the third floor, because the temperature and humidity are high in summer, which is suitable for the growth of red nematodes, and a large number of them survive in sewer ditches and pipes.

3. Solution.

1. It is necessary to strengthen the management of secondary water supply facilities such as water tanks, and carry out maintenance, cleaning and disinfection in a timely manner to prevent red nematodes from growing and growing in water.

Users living in disturbed rooms and low floors should pay attention to the hygiene of the water environment, keep the tap water pool clean, try not to place brooms, rags and other wet objects next to the tap water pool at night, and plug the tap water pool drain with a plug.

Qualified users can also frequently disinfect the sewer pipes to prevent red nematodes from crawling outside.

2. The water tank must be cleaned twice a year and disinfected once a year.

Generally, disinfection shall not be less than once every six months to prevent the growth of nematodes in the water; If nematodes appear in the water, bleaching powder can be used to kill the insects; Qualified users can also often use "84 disinfectant", bleaching powder, bottled household disinfectant, etc. to disinfect long-term wet areas such as sinks and sewer pipes to prevent red worms from crawling outside.

Precautions. If the household solar water heater is not in use for a long time, the water should be completely emptied, and the disinfection and cleaning should be paid attention to when re-use, otherwise red worms may also breed. Therefore, the owner should ask the property management company entrusted by him to clean the water tank in time to ensure the water quality.

Here's how:

Improve the environment after winter fishing or before the arrival of the spring rainy season with quicklime disinfection, the amount of 25 40 grams of cubic meters, at this time less medicine, can save investment.

After disinfection, use conventional insecticides to kill insects once 90% crystal trichlorfon grams cubic meters or new insecticides, and the dosage is as indicated.

Before releasing the fish, the medicated bath is disinfected with 20 grams of potassium permanganate soaked for 15 20 minutes or 500 grams of crystal trichlorfon cubic meters soaked for 15 minutes.

Reasonable stocking density is too large or unreasonable combination will make the activity space of fish relatively reduced, and the fish will secrete too much adrenaline hormones, and the physical strength will decrease, thereby increasing the chance of enrichment and dispersal. Strengthen management to avoid stress response and improve the resistance of the fish itself.

Feed the bait. 100 grams of trichlorfon mixed into 30 kg of bran or compound feed for 4 days.
