High-stability water quality purification system for polluted riverway and purification method thereof

Abstract

The invention discloses a high-stabilitywater quality purification system for a polluted riverway and a purification method thereof. The high-stability water quality purification system comprises a regulating reservoir, an MBBR biochemical pool and a KtCQ purification system, wherein the regulating reservoir is connected with an on-line conductivity detector and an on-line pH value detector; a water outlet of the regulating reservoir is further connected with a water inlet of the KtCQ purification system through a first pipeline; a first electric valve is arranged on the first pipeline; the regulating reservoir and the MBBR biochemical tank are connected through a second pipeline; a second electric valve is arranged on the second pipeline; and a first dosing device for adding acid, alkali and a heavy metal remover is further connected to the first pipeline. According to the invention, heavy metal or sewage with a pH value not reaching the standard can be timely subjected to split-flow treatment, so the heavy metal or the sewage with the pH value not reaching the standard is prevented from entering the MBBR biochemical pool, sewage treatment effect is guaranteed, and the MBBR biochemical pool can be effectively protected; and meanwhile, feedback is fast, use is convenient, cost is low, and emergency treatment can be well conducted on industrial wastewater drainage and environmental pollution.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a highly stable polluted river water purification system and a purification method thereof. Background technique [0002] Traditional river pollution usually means that the river is polluted by domestic sewage. Conventional river water purification systems generally include regulating tanks, biochemical tanks, and solid-liquid separation purification systems, which are very effective in treating domestic sewage; however, with the continuous development of industry And the environment is getting worse and worse, and the environmental pollution is becoming more and more serious. Some rivers may be polluted by industrial waste water or other pollution sources, resulting in heavy metals or pH values ​​that are not up to standard. Once these waste water enters the biochemical pool, not only cannot be well If it is purified, it will also damage the various bacteria in the biochemical po...

[0002] Traditional river pollution usually means that the river is polluted by domestic sewage. Conventional river water purification systems generally include regulating tanks, biochemical tanks, and solid-liquid separation purification systems, which are very effective in treating domestic sewage; however, with the continuous development of industry And the environment is getting worse and worse, and the environmental pollution is becoming more and more serious. Some rivers may be polluted by industrial waste water or other pollution sources, resulting in heavy metals or pH values ​​that are not up to standard. Once these waste water enters the biochemical pool, not only cannot be well If it is purified, it will also damage the various bacteria in the biochemical pool, destroy the internal balance of the biochemical pool, and thus affect its sewage treatment effect; and the conventional river water purification system cannot well deal with the problems of industrial wastewater discharge and environmental pollution emergency treatment
