Description

technical field [0001] The invention relates to purification equipment in the technical field of water supply, in particular to an integrated water purification treatment equipment integrating coagulation, flocculation, clarification, precipitation, sludge concentration, sludge automatic return and pressure water outlet. Background technique [0002] In recent years, the country has vigorously advocated the development of small and medium-sized cities and towns. The rural population has concentrated in small and medium-sized cities and towns. The number and scale of small and medium-sized cities and towns have continued to increase. Simple and simple household water supply is difficult to meet the needs of urbanization development. With the promulgation of my country's new drinking water quality standard (GB5749-2006) and its implementation in water supply systems of different scales, the traditional water purification treatment technology with concrete as the main result has...

AI Technical Summary

Problems solved by technology

[0003] 1) The adaptability of the equipment to the raw water quality is not strong

When the influent water quality changes greatly, due to the lack of necessary technical measures to improve the raw water quality, the solid load of the treatment fluctuates greatly, and the treatment effect cannot be guaranteed

For example, the existing integrated equipment has a poor treatment effect on the reservoir as the water source in the northwest region, high turbidity water in summer and autumn torrential rain seasons, and low temperature and low turbidity raw water in winter and spring.

[0004] 2) The equipment has poor adaptability to changes in the water purification load

Currently limited by the volume and height of the equipment, the flocculation area of ​​the integrated water purification equipment is small, resulting in insufficient flocculation, and the floc particles formed are small and loose, which are easy to be carried out, resulting in deterioration of the effluent water quality

[0005] 3) The precipitation efficiency of the equipment is low

The fillers used in the sedimentation area are generally inclined tubes and inclined plates. The stirring shaft passes through the center of the sedimentation area of ​​some equipment, resulting in damage to the integrity of the inclined plate or inclined tube. Moreover, it is easy to cause a large proportion of dead water areas, resulting in sedimentation. Reduced space utilization in the area

[0006] 4) When inclined plate or inclined pipe is used in the sedimentation area, there is no kinetic energy in the water outlet of the equipment, and the connection options of subsequent filtration equipment are limited

In order to ensure that there is no short flow in the sedimentation area of ​​the equipment, a perforated pipe or a sawtooth weir gravity drop is set on the upper part of the sedimentation area to collect the water from the sedimentation area, so that the subsequent filtration equipment can only use the potential energy of the water outlet of the equipment, and the gravity filter can only be used by reducing the installation height of the equipment. Or pressurize again in the middle to use the pressure filter

[0007] 5) The adsorption of sludge is not utilized

[0008] 6) The solid content of the sludge water is low, and the water production rate of the equipment is low

Natural sedimentation is generally adopted in the sludge sedimentation area, which does not have the function of sludge concentration, and the sedimentation efficiency is low, resulting in a large amount of water and sludge being discharged together as sludge discharge water
