Ecological water slow-filtering and taking system

Abstract

An ecological water slow-filtering and taking system comprises a pretreatment water distribution area, an ecological plant area, a water slow-filtering and purifying area and a water collecting well. The pretreatment water distribution area comprises an open water inlet channel, a skimming pipe, a sand setting water distribution tank and a water distribution branch pipe, wherein the open water inlet channel, the skimming pipe, the sand setting water distribution tank and the water distribution branch pipe are connected in sequence. The water distribution branch pipe is arranged between the ecological plant area and the water slow-filtering and purifying area, and the ecological plant area is arranged at the top of the water slow-filtering and purifying area; a ventilating pipe extending out of the ecological plant area is arranged on the water distribution branch pipe, and a water distributing hole is formed in the bottom of the water distribution branch pipe; herbaceous plants are planted in the ecological plant area, the water slow-filtering and purifying area is filled with filter materials, and a water collecting main pipe is arranged at the bottom of the water slow-filtering and purifying area and connected with a water outlet pipe; the water outlet pipe is arranged in the water collecting well; the water outlet end of the water outlet pipe is controlled to be lower than the water distribution branch pipe; a lifting pump is arranged at the bottom of the water collecting well. The ecological water slow-filtering and taking system enables plant ecological treatment and water slow-filtering and purifying treatment to be combined together, and is good in water purifying effect, free of back wash and convenient to run and manage.

Description

technical field [0001] The invention relates to a water intake system for purifying river water by adopting an ecological slow filtration technology, and belongs to the technical field of slow filtration water treatment. Background technique [0002] With the development of industry and the progress of society, drinking water treatment has attracted more and more attention. How to ensure the safety of people's drinking water while minimizing the cost of water treatment management and operation has become the focus of attention. At present, most domestic waterworks pump water up to the ground through traditional river bank water intake devices, and then send it to users after a series of conventional treatment processes, such as coagulation, sedimentation, filtration, and disinfection. The water quality obtained by this treatment method is poor, and maintenance and cleaning are inconvenient, and a complete set of water treatment system needs to be built on the ground, and th...

Problems solved by technology

However, the existing ordinary slow filter equipment has a single structure and function, and cannot fully exert the microbial degradation effect on the removal of pollutants. The processing capacity is limited and the effect is average.
