Embodiment Construction

[0028]In the method of the invention, the lined canals on both sides of the river are used as structures for sewage treatment, and special treatment plants are no longer constructed. Both the contact oxidation aeration tank and the air flotation tank are placed in the water channel, and the coarse grid and the fine grid are also arranged in the water channel.

[0029] In order to treat 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.

[0030] Such as figure 1 Shown, in one embodiment of the present invention, the water purification method of river and lake comprises following flow process:

[0031] 1. Coarse grid filter:

[0032] Grille is an essential equipment in the sewage treatment industry. Especially in the open water environment in the canal, people discard a lot of solid waste such as plastics and papers. It is necessary to use grilles ...

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 rapid development of social economy, the industrialization and urbanization of human society are increasing 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 been increasing at a rate of 5% every year, surpassing the discharge of industrial sewage for the first time in 1999. In 2001, the discharge of urban domestic sewage was 22.1 billion tons, accounting for 53.2% of the total discharge of sewage in the country. In 2002, the total discharge of domestic industrial and urban domestic wastewater was 43.95 billion tons, of which the total discharge of urban domestic wastewater was 23.23 billion tons, an increase of 0.9% over the previous year. Due to such a huge pressure of sewa...
