Abstract

The invention belongs to the technical field of environmental protection, especially the technical field of water treatment, and relates to a device for purifying water in river, ponds or lakes. The device is characterized in that the water is pumped into a biological reactor of biological fillers with a plurality of pore structures by gas stripping, and is purified in the biological reactor, and the purified water naturally flows back to a water body from the biological reactor. The device has the beneficial effects that due to adoption of a gas-stripping and extraction mode, the energy consumption is greatly reduced; due to adoption of the biological reactor of the biological fillers with the plurality of pore structures, the use of a precipitation tank is avoided, and the water-body purifying method with gas stripping and extraction becomes possible; the generation of a great amount of biological sludge is avoided; a water-quality purifying effect and a energy-saving effect are obvious.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to the technical field of water treatment, and relates to a device for purifying river, river, pond or lake water by using a fixed-bed bioreactor. technical background [0002] With the development of the economy, the pollution of water bodies by human beings has become more and more serious. Among them, the purification of rivers, rivers, ponds and lakes (hereinafter collectively referred to as water bodies) has gradually become a problem that human beings must face. [0003] In the known technology, there is a technology of adding chemicals to the water body to purify the water quality through flocculation and sedimentation. This technology not only cannot effectively purify the water body, but also increases the environmental burden. Known technologies include adding bactericides to water bodies, and these bactericides include ozone, inorganic salts, enzyme pre...
