Problems solved by technology

In addition, although some land treatment systems, such as the underground infiltration system with enhanced water distribution, can greatly improve the removal of nitrogen and phosphorus in sewage, the soil is easy to clog, the sewage treatment flow is small, the area is large, and the operation is difficult. Complicated methods and other issues, and need to consume power

Embodiment 1

[0027] The composite filler in the constructed wetland system is prepared by mixing 85% slag, 10% red soil and 5% humus according to the volume ratio. The wetland area is 5m2, the depth is 60cm, and the slope is 0.5%. The first third section is planted with reeds, and the second third section is planted with Zizania sinensis. The water distribution pipe adopts a PVC pipe with a diameter of 25mm, and the holes are drilled at intervals along both sides of 90°, the hole spacing is 10cm, and the hole diameter is 2mm; the collecting pipe is a PVC pipe with a diameter of 50mm, and the holes are drilled at intervals along both sides of 90°, and the hole spacing is 10cm. , The aperture is 10mm. The diameter of the adjustable hose is 50mm. The stone water distribution area and water catchment area are filled with pebbles with a diameter of 30-60mm. The hydraulic load of the system is 4cm / d, and the sewage is fed in by continuous batching of sewage, and the proportion of sewage diversion at...

[0029]The composite filler in the constructed wetland system is prepared by mixing 50% slag, 30% red soil and 20% humus according to the volume ratio. The wetland area is 5m2, the depth is 80cm, and the slope is 1%. The first third section is planted with reeds, and the second third section is planted with water chestnuts. The water distribution pipe adopts a PVC pipe with a diameter of 25mm, and the holes are drilled at intervals along both sides of 90°, the hole spacing is 10cm, and the hole diameter is 5mm; the collecting pipe is a PVC pipe with a diameter of 50mm, and the holes are drilled at intervals along both sides of 90°, and the hole spacing is 10cm. , The aperture is 10mm. The diameter of the adjustable hose is 50mm. The stone water distribution area and water catchment area are filled with pebbles with a diameter of 30-60mm. In addition, a reference wetland is set up with the same structure and operating conditions, but the traditional filling method is used for the in...

Embodiment 3

[0031] The composite filler in the constructed wetland system is prepared by mixing 60% slag, 25% red soil and 15% humus according to the volume ratio. Wetland area is 5m 2 , The depth is 120cm, the slope is 2%, the first third section is planted with reeds, and the second third section is planted with Zizania. The water distribution pipe adopts a PVC pipe with a diameter of 25mm, and the holes are drilled at intervals along both sides of 90°, the hole spacing is 10cm, and the hole diameter is 5mm; the collecting pipe is a PVC pipe with a diameter of 50mm, and the holes are drilled at intervals along both sides of 90°, and the hole spacing is 10cm. , The aperture is 10mm. The diameter of the adjustable hose is 50mm. The stone water distribution area and water catchment area are filled with pebbles with a diameter of 30-60mm. In addition, a reference wetland is set up. The wetland structure and operating conditions are the same, but the internal filling is made of slag and general ...

Abstract

A method and system for treating sewage, especially the lift sewage, by artificial nunja features that the sewage is uniformly distributed into an air and water permeable composite filler layer composed of cinder laterite and humics, and the plant with high oxygen-releasing power of its root, fast growth and high power to absorb nitrogen and phosphorus is planted in the filler layer. Its advantage is high treating effect and capacity.

Description

Technical field [0001] The present invention relates to a sewage treatment and sewage regeneration and reuse technology, in particular to a land treatment for domestic sewage in scattered residential areas such as towns, mountain areas, vacation villages, sanatoriums, and urban residential communities and for sewage regeneration and recycling. With the system, it can also be used for small-scale industrial wastewater treatment. Background technique [0002] In recent years, with the development of economy and society, environmental problems have become increasingly prominent, and the requirements for sewage treatment have become higher and higher not only in cities but also in towns. Domestic sewage in scattered residential areas such as townships, mountainous areas, and villa areas carries a large amount of nitrogen, phosphorus, organic matter and other pollutants into the water body, causing the water body to face the danger of serious eutrophication. In addition, with the incr...
