With the rapid development of the economy, sewage collection and treatment equipment is seriously lagging behind, resulting in many sewage directly entering the river. Now, most rivers have become black and odorous water bodies, and the water quality standards cannot meet the requirements of section assessment. Therefore, measures need to be taken for treatment. The commonly used methods for river water purification treatment now include pipeline interception, scattered construction of small sewage treatment stations, and magnetic separation temporary pollution control methods. However, among the existing three sewage treatment methods, there are still shortcomings such as large investment in pipeline interception networks, large demolition volumes in urban areas or other densely populated areas, generally requiring implementation along with regional planning, and long completion cycles.

The disadvantages of decentralized construction of processing stations are high investment and operational management costs, and the problem of land occupation is not easy to solve. The magnetic separation skill can only remove a portion of insoluble pollutants, with low removal rates of ammonia nitrogen and total phosphorus. The effluent quality is still inferior to Class V water quality, far from meeting the water quality requirements of the assessment. Moreover, it is prone to secondary pollution caused by many chemical sludge to the environment.

Skill completion strategy:

The intention of this skill is to provide a sewage ecological clean water system. The intention of this skill is to complete it through the following skill scheme: a sewage ecological clean water system, including a purification box, wherein the purification box is equipped with several purification carriers, the purification carrier is a porous component, and the porosity on the purification carrier is 5% -80%; The shape of the purification carrier includes block, spherical, or columnar shapes; The particle size scale of the purification carrier is 1-80mm; The purification carrier contains at least one piece of construction waste. Furthermore, the construction waste comprises at least one of crushed stones, block stones, angular gravel, round gravel, and abandoned blocks; Furthermore, the purification carrier further comprises auxiliary fillers, which include quartz sand, activated carbon, ceramic particles, volcanic rocks, manganese sand, sponge iron, anthracite, pebbles, fiber balls, diatomaceous earth, porous glass, zeolite, new bricks, new concrete, medium sand, and one or several types of coarse sand. Furthermore, the outer surface of the purification carrier is attached with a biofilm layer, which is a membrane layer formed by the composite cultivation of several active microorganisms.
