Purification device for ecological restoration of flowing black and odorous water

Abstract

The invention discloses a purifying device for ecological restoration of liquidity black smelly water and belongs to the field of environmental protection.The purifying device comprises a drip irrigation device, the drip irrigation device comprises a liquid storage box, a header pipe, a slow-speed branch pipe, a high-speed branch pipe, a first switch valve, a second switch valve, a third switch valve, a drip irrigation pipe, a hand-cranking winch, a water pumping pump and a steel wire; one end of the header pipe is connected with the liquid storage box, the other end of the header pipe is connected with one end of the high-speed branch pipe and one end of the slow-speed branch pipe, the other end of the high-speed branch pipe and the other end of the slow-speed branch pipe are connected with one end of the drip irrigation pipe, one side of the drip irrigation pipe is evenly provided with drip irrigation openings, and the side, where the drip irrigation openings are distributed, of the drip irrigation pipe is placed on the river surface in a mode of being downwards perpendicular to the river bank.The purifying device has the advantages that the purifying device can delay release of microorganisms, multi-purification is achieved, and the purifying effect is good; a cured microorganism filtering device can remove replaced phosphorus, and secondary pollution is avoided; the device is flexible to apply and high in practicability.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a purification device for ecological restoration of fluid black and odorous water bodies. Background technique [0002] With the rapid development of society and the rapid increase of population, the discharge of sewage in our country has also increased significantly. The urban sewage treatment system cannot meet the increasing amount of sewage discharge, and there is a serious phenomenon of illegal and leaky sewage drainage, which has led to serious pollution problems in my country's water bodies. [0003] Among various water body treatment technologies, microbial technology has been widely used in water environment treatment due to its advantages of ecological coordination, safety and environmental protection, and not easy to produce secondary pollution. Adding artificially enhanced beneficial microbial flora to ponds, lakes and other slow-flowing water bodi...

AI Technical Summary

Problems solved by technology

Adding artificially enhanced beneficial microbial flora to ponds, lakes, and other slow-flowing water bodies can fundamentally alleviate the problems of black, odorous, and eutrophication in water bodies, but in water bodies such as rivers with strong fluidity or "three-sided light" In the process, the added microorganisms will be lost in large quantities with the flow of the water body, causing it to fail to exert its original effect

On the other hand, in the process of denitrification and phosphorus removal from water bodies, nitrogen pollutants are easily converted into nitrogen gas and completely removed from the water body, while phosphorus has no gaseous form and can only exist in a dissolved or granular state, making it difficult to completely leave the water environment. There is a risk of secondary release, which must be removed through the sludge discharge process, which increases the difficulty and cost of treatment
