Environmental protection in animal husbandry. (1987)

Bare birches.

The lost forest.

River.

Rotten wood, dead trees.

Water sample in the river.

Water pollution of the Drozdov Lake on Ladoga.

Dying birds.

Tells an old-timer on Ladoga.

Panorama of livestock farms.

Removal of manure effluents from pig farms to the fields.

The removal of wastewater leads to waterlogging, loss of soil fertility, pollution of the atmosphere and soil, surface and groundwater.

On their household farm, residents use almost 100% animal waste.

The use of manure in the garden.

Haystack.

Mountain river.

A fawn near the river.

A herd of deer.

Bear near the river.

Laboratory for the control of wastewater treatment.

Phyto and zooplankton.

It is determined at what degree of pollution in the reservoir the process of self-purification is disrupted.

Dead fish.

Dead fish are tested for toxic substances.

Professor Herman Alexandrovich Talanov tells.

Sewage treatment plants of a livestock enterprise.

A cartoon explaining the work of the purification system.

The storage tank is a sump before filling.

Drainage system in the concrete bottom.

The sediment in the sump is a valuable fertilizer.

When the diluted liquid fraction is transferred along the cascade of ponds, natural aeration occurs, i.e. oxidation of the components of the runoff.

Laboratory technicians carry out water control.

A water purification system close to the natural one allows almost complete disposal of wastewater.

Purified water can be used for technical needs.

In it, without feeding, young fish are grown in fish-breeding ponds.

Fishermen are fishing on the lake.

High-rise new buildings.

People buy milk, cheese, meat in the store.

Panorama of the livestock complex.

Cows in the stalls.

Cartoon explaining the work of the cleaning system of the livestock complex.

Separation of solid fraction of waste.

Screw press for waste dewatering and feeding it to the storage site.

Dry waste from livestock farms can be mixed with peat and straw.

Compost preparation.

The liquid fraction is diluted with pond water.

Powerful pumps pump water into the mixing tank.

Rotary turbines mix it with drains.

A cartoon explaining the cleaning process.

Cows in the fields.

Harvesting of green mass for silage and haylage.

Laboratory testing of the content of nitrates and nitrites in the green mass.

The result of the analyses depends on whether or not to continue watering the fields with a liquid fraction of waste.

Checking the water for the content of pathogens of salmonellosis and tuberculosis, other infectious diseases.

Sanitary service.

Analysis of the air condition near the complex.

Inspection of surface and underground waters.

Flood.

Boarded up house.

Chicks on human hands.

Poultry farm.

Collecting and packing eggs at a poultry farm.

Thermal installations for processing bird droppings.

After such treatment, the manure turned into pellets becomes a valuable organic fertilizer.

Packaging of pellets in bags.

There is a biological treatment for wastewater at the poultry farm.

Laboratory testing of purified water.

Methane fermentation purification complex.

Through underground pipes, manure enters the storage tanks.

Fermentation of manure is carried out.

After the release of methane, the manure turns into a biologically pure fertilizer.

Methane is used as an energy source.

VDNH OF the USSR.

Space.

The earth is like a heart.

The troposphere.

Hydrosphere.

Lithosphere.

All the elements that make up the biosphere.

Academician Alexander Leonidovich Yanshin tells.

Ocean waves.

Horses graze.

People ride horses.

Birds take off from the pond.

A chick hatched from an egg.

The chicks are in the nest.

Lotus on the surface of the reservoir.
