Sewage ecological water-purification system

Abstract

The invention relates to a sewage ecological water-purification system including a purifying box body; the purifying box body is internally provided with a plurality of purification carriers, and the purification carriers are porous materials and include the component of construction waste, wherein the construction waste has the particle size range of 1-80 mm and includes at least one of broken stone, block stone, angular gravel, round gravel and waste blocks; the purification carriers are attached with a biofilm prepared from a biological preparation, and the biological preparation is formed by composite culture of a plurality of active microorganisms. The system has the advantages of high purification efficiency, thorough purification, water quality improvement, low investment and operation costs, convenience in construction, good film-hanging effect, and no cause of secondary pollution to the environment.

Description

technical field [0001] The invention relates to a purification system, in particular to a sewage ecological water purification system. Background technique [0002] With the rapid development of the country's economy, sewage collection and treatment facilities are seriously lagging behind, causing a large amount of sewage to flow directly into the river. At present, most rivers have become black and odorous water bodies, and the water quality standards cannot meet the requirements of cross-section assessment. Therefore, measures need to be taken for treatment. [0003] The commonly used river water purification treatment measures mainly include pipeline sewage interception, decentralized construction of small sewage treatment stations, and temporary pollution control measures of magnetic separation. However, in the above three existing sewage treatment methods, there are still relatively large investment in the pipeline network for intercepting sewage, large demolition in ur...

AI Technical Summary

Problems solved by technology

Disadvantages of decentralized processing stations are large investment and operation management costs, and the problem of land occupation is not easy to solve

The magnetic separation technology can only remove part of the insoluble pollutants, the removal rate of ammonia nitrogen and total phosphorus is extremely low, and the effluent water quality is still inferior to Class V water quality, which is far from meeting the water quality requirements of the assessment, and it is easy to produce a large amount of chemical sludge that is harmful to the environment cause secondary pollution
