Description

Device to prevent the growth and reproduction of blue-green algae

in water

The invention relates to a technology for the purification of water from algae in reservoirs, rivers, lakes, pools, storage pruts, and can also be used in technological, drinking, and sanitary water supply systems.

From a great way to purify water from algae (AS. USSR No. 1013414 CO 2 F 1/50) by the bottom introduction of chlorine and the creation of air curtains with air. The air curtain formed by passing air into the depths creates a breaker on the surface. Exposure to air oxidizes part of the algae. The supply of chlorine water to the bottom, away from the air curtain, provides a constant dose of chlorine oxidizing agent, which, acting on algae, oxidizes them

A significant disadvantage of this method is that water purification does not occur locally in a small area at high energy consumption., And also the use of chlorine adversely affects the flora living in the reservoir, and in addition, when combined with organics (algae are partially organic), it forms carcinogenic compounds.

The aim of the invention is to study the causes of flowering ponds and the creation of environmentally friendly methods for cleaning them.

Based on the studies, the following was established: in the warm season, most of the time in shallow water in reservoirs, the water warms up above 20 ° C. With this heating, the content of oxygen dissolved in water decreases, as well as the accumulation of fertilizers in the form of phosphates, nitrates and other minerals washed away from the fields during spring and rain floods. The resulting environment contributes to the increased growth and reproduction of blue-green algae in the warm season of the year. 1 In order to prevent the growth of green algae, it is necessary to prevent overheating of the water in the water bodies and also to clear the water of phosphates, nitrates and other minerals.

Conducted experiments on finding material that could regulate the temperature of water in Wodsme, as well as neutralize minerals, i.e. create an environment that did not allow the reproduction and growth of blue-green algae. The best indicator for straw of cereal plants, and the best indicator gave barley straw

Example 1. Dry barley straw with a log weighing 1 kg during combustion gives the following ash indicators: phosphates - 0.05 mg / kg, nitrates - 0.07 mg / kg.

Example 2. Viewed barley straw, which has been in the pond for 5 years, weighing 1 kg when burning and checking for ash gives the following indicators: phosphates - 40 - 45 mg / kg, nitrates - 37 - 50 mg / kg. The results of the study showed that barley straw is suitable for achieving the goal in the fight against blue-green algae in ponds, which, when in water, absorbs phosphates and nitrates, thereby inhibiting and stopping the growth and reproduction of blue-green algae. It is also important that a flat surface of barley straw, being in the water at a depth of 10-15 cm from the surface, almost completely reflects the rays of the sun. SBA rays are in the same plane cL JO - this is the law of total reflection. The law is valid if the optical medium is rigid.

The purpose of the image is the creation of barley straw devices that are affordable, cheap, environmentally friendly, which can effectively deal with blue-green algae over the entire area of water bodies.

In FIG. 1 shows a section of barley straw No. FIG. 2 shows mat assembled from sections. A mat of 2m x 2ivi x 0.3m in size is able to regulate water temperature up to 18 ° C in the hot season on 100 m2 of the surface of the reservoir, this mode slows down the growth and reproduction of blue-green algae on 10СЫ2 surface of the reservoir for 5 years. No. Fig L barley straw -1 is tied with nylon cord-2, thereby creating a section.

BHA FIG. 2 mat shbratshshh sections, secured to concrete cargo anchor -3 and a depth of 15-20 cm from the bottom of the reservoir and 10-15 cm from the surface of the water Barley straw mats are used in coastal zones up to 1 meter deep

For use with a depth of more than 1 meter, a device of four bales of barley straw is used - FIG. 4. In Fig. 3, a bale of cubic barley straw up to 1 meter in size is tied with a nylon cord - 2.

Bookmark devices made from barley straw in a pond in autumn or spring - this contributes to the accumulation of temperature until the hot season. Using barley straw from these devices will allow you to effectively deal with pollution from greengrass algae in water bodies of various areas.
