Integrated water purifying equipment for concurrent inclined plate precipitation

Abstract

The invention relates to integrated water purifying equipment for concurrent inclined plate precipitation. A main body is concentrically partitioned into inner, middle and outer cylinders, which are respectively a flocculation zone, a filter zone and a concurrent inclined plate precipitation zone, wherein a water distributing zone is arranged at the upper segment of the concurrent inclined plate precipitation zone; an inclined plate group zone is arranged at the middle segment; a sludge concentrating chamber is arranged at the lower end; a water collecting zone is arranged between the water distributing zone, the inclined plate group zone and the filter zone; the bottom part of the water collecting zone is respectively communicated with the inclined plate group zone and the filter zone through pores; a circle of inclined plates are evenly distributed in the inclined plate group zone; the inclination angles theta of the inclined plates are 30-45 degrees; and the pores are arranged at the positions between the tail ends of two adjacent inclined plates at the bottom part of the water collecting zone and are communicated with the inclined plate group zone and the water collecting zone. The concurrent inclined plate precipitation technique is applied to the integrated water purifying equipment; flocculation, concurrent inclined plate precipitation and filtering are combined together; and the treatment process is independently and synergetically finished, so that the flocculation, concurrent inclined plate precipitation and filtering fully develop the advantages; and the integrated water purifying equipment is good in treatment effect, compact and reasonable, small in floor area, and convenient to install.

Description

technical field [0001] The invention relates to water treatment and purification equipment, in particular to an integrated water purification equipment used for sedimentation of co-current inclined plates in water supply and drainage. Background technique [0002] For a long time, water supply and drainage workers have been committed to the research and development of various integrated water purification equipment. At present, various integrated water purification equipment have been developed for this purpose, but these integrated water purification equipment are all conventional process combinations, which only combine flocculation, sedimentation, and filtration into various forms. But so far, the co-current inclined plate sedimentation technology has not been introduced into the integrated water purification equipment. [0003] Cocurrent inclined plate (tube) sedimentation technology is a high-efficiency sedimentation technology. In 1967, the "Lamera" separator (that i...

Problems solved by technology

However, due to the following shortcomings of this precipitation technology, it is difficult to use this efficient precipitation technology in production practice:

[0004] 1. The structure of the catchment area is very complicated. Since the direction of mud flow and water flow is the same during the sedimentation process of the co-current inclined plate sedimentation device, it is necessary to set up a water collection channel at the end of the sedimentation to collect clean water, and discharge the collected clean water through the return pipe

There are various shapes of catchment areas, such as knife shape, comprehensive resistance type, trapezoidal shape, etc., but the structure is very complicated, it is not convenient for construction and assembly, and the cost is expensive

[0005] 2. Since a catchment area needs to be set between the two sloping plates to collect the sunken water, the distance between the two sloping plates cannot be too small, so that the sedimentation area is limited to a certain extent

Moreover, a section of mud slab is added at the end of the sedimentation, which increases the cost and difficulty of installation

[0006] 3. The holes in the catchment area are easy to block. The hole diameter of the catchment area is generally in the range of Φ4~Φ10mm. After a period of operation of the device, some holes are easily blocked and cannot work normally, which seriously affects the sedimentation efficiency of the device.

[0007] 4. The body of the co-flow inclined plate sedimentation tank is unevenly distributed, and the liquid level of the inclined plate is similar to an advection type sedimentation tank body with water outlet along the way. The inlet is less, resulting in the concentration of sludge at the end is much higher than that at the rear, and there will be sludge accumulation on the inclined plate at the end
