Description

Integrated water purifier

technical field

The utility model relates to an integrated water purifier, in particular to an integrated water purifier for reuse after advanced treatment of drinking water for urban and rural residents, water quality for industrial and mining enterprises, and part of industrial waste water and domestic sewage.

Background technique

With the continuous development of modern production, resources are becoming more and more tense, and the world of water resources is also facing a harsh reality. The south of my country is short of water quality, and the north is short of water quantity. The available water resources are showing a downward trend. With the continuous development of human society, people's needs have also increased accordingly. People have different production needs and have different requirements for water quality. The existing first-generation water purifiers (FXZ) and second-generation water purifiers (TLZ) fully met the needs of enterprises at the initial stage. Due to the corresponding improvement of water quality and quantity standards for enterprise development, the original water purifiers could not meet the relevant requirements. The water purifier is a fully automatic water purification device integrating reaction, sedimentation, filtration and other purification processes. However, the original product has the disadvantages of low water quality, small water production and high sewage discharge, which no longer meet the increasingly high national water purification parameter requirements. For example, the condensate in the water body is a viscous substance, which directly contacts with the quartz sand filter material layer, and the surface layer of the quartz sand is easy to harden, which is not conducive to backwashing and consumes more water.

The integrated water purifier described in the utility model is a fully automatic water quality purification device that integrates purification processes such as coagulation reaction, precipitation, and filtration. Advanced technologies such as flocculation reaction, inclined plate sedimentation, and multi-media filtration are adopted. Dosing is used to make the suspended particles in the raw water gradually form larger flocs through flocculation reaction. After sedimentation in the inclined tube, most of the flocs are removed, and the remaining fine flocs are further removed by filtration to keep the turbidity of the effluent water at Below 1mg/l. When the water purifier is running, due to the continuous retention of flocs in the filter layer, the head loss of the filter increases. When the head loss value specified in the design is reached, the filter will be backwashed to remove the impurities trapped in the filter material, so that it can restore the water purification function and maintain normal operation. The sludge is discharged by gravity, so no external power is needed.
