Urban landscape type rotating rain spraying type multi-layer photocatalysis ecological purification tower

Abstract

The invention provides an urban landscape type rotating rain spraying type multi-layer photocatalysis ecological purification tower. The tower comprises water-permeable trays, photocatalysis water-permeable basins, ceramsite, plants, a central supporting column, a water pump, a water feeding pipe, a rain spraying pipe, a rotating device and a solar device. The tower has the advantages that the four water quality purification methods including the plant root absorption method, the interception and filtration method, the photocatalysis degradation method and the aeration and oxygenation method are integrated into a whole, the advantages of all the purification methods for removing pollutant in water are brought into full play, the complementary type purification technology is formed, concentration of pollutant such as organic pollutant, heavy metal and the like in water can be effectively reduced, and the water quality purification efficiency can be improved; the water-permeable basins are made of porous foamed ceramic, and therefore the improvement of the sewage purification efficiency of photocatalysis membranes is facilitated; the multi-layer tower type structure is adopted, sewage is filtered and purified layer by layer from top to bottom, and the purification efficiency is high; natural light can directly irradiate the photocatalysis membranes, the rain spraying pipe is of a rotatable type structure, the flowing speed is decreased, sewage can be dispersed, and a purification layer below can be covered in a full-area mode.

Description

technical field [0001] The invention relates to a sewage purification device, in particular to an urban landscape type rotating rain-drenching multi-layer photocatalytic ecological purification tower, which belongs to the technical field of sewage treatment. Background technique [0002] With the rapid development of my country's industrialization and the further improvement of agricultural intensification, industrial sewage, agricultural sewage and domestic sewage have caused serious damage to the water environment. A large amount of untreated or incompletely treated sewage is directly discharged into rivers, lakes and other water bodies, resulting in the overall deterioration of the water quality of rivers and lakes. With the continuous advancement of the modernization process, building a harmonious water environment for humans and water has become an important measure to enhance urban competitiveness, improve urban quality, and develop the economy. However, due to the di...

Problems solved by technology

However, due to the different formation methods and sources of pollutants, there are many types of pollutants dissolved or suspended in water bodies, complex components, and poor biodegradability. Traditional water treatment methods such as biodegradation, physical adsorption, coagulation precipitation, electrolysis, General oxidation methods can only remove a certain type of pollutants in a targeted manner, while multi-method and multi-pass series treatment will greatly increase the cost of sewage treatment
