Embodiment Construction

[0027] In the method of the invention, the lined canals on both sides of the river are regarded as structures for sewage treatment, and no special treatment plant is built. The contact oxidation aeration tank and the air flotation tank are placed in the water channel, and the coarse and fine grids are also set in the water channel.

[0028]In order to carry out treatment directly in the canal, the total hydraulic retention time of the sewage must be designed to be sufficient for 8-12 hours to create conditions for aeration and aerobic purification.

[0029] like figure 1 As shown, in one embodiment of the present invention, the water purification method of rivers and lakes includes the following processes:

[0030] 1. Coarse grid filter:

[0031] The grille is an essential equipment in the sewage treatment industry. Especially in the open water environment in the aqueduct, people discard a lot of solid waste such as plastic and paper, and these coarse wastes must be interce...

Abstract

A method for cleaning the water in river and lake features that the stream generating and aerating apparatus is arranged in the water of river or lake to generate artificial streams and increase the content of O2 in water for changing the river or lake into a contact-oxidizing aerating pool, and the biological-bed filler is arranged in each stream path to decompose the organic pollutants in water. Said apparatus is composed of turbulence pump, water inlet pipe and outlet pipe with single-pole magnetic rings, and mixing pipe.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a water purification method and equipment for rivers and lakes. Background technique [0002] With the high development of social economy, the industrialization and urbanization of human society are intensifying day by day, and water pollution is becoming more and more serious. In the past 10 years, the discharge of urban domestic sewage in my country has increased at a rate of 5% every year, and in 1999 it exceeded the discharge of industrial sewage for the first time. In 2001, the urban domestic sewage discharge amounted to 22.1 billion tons, accounting for 53.2% of the national total sewage discharge. In 2002, the national industrial and urban domestic wastewater discharge totaled 43.95 billion tons, of which the total urban domestic wastewater discharge was 23.23 billion tons, an increase of 0.9% over the previous year. Due to such a huge pressure of sewage discharge...
