Clarified ultrafiltration water processing device

Abstract

The invention relates to a clarified ultrafiltration water processing device. A water inlet tube is communicated with a pre-sedimentation chamber with a mud discharging tube, and the pre-sedimentation chamber is arranged below a volume flocculation chamber in a communicated mode. An activated sludge chamber is coaxially arranged outside the volume flocculation chamber, and the volume flocculation chamber is formed by the mode that two or more stages of flocculation chamber cylinders are coaxially connected in a sleeved mode and are communicated in sequence. The bottom of the innermost stage of flocculation chamber cylinder is communicated with the pre-sedimentation chamber, and the end, where two flocculation chamber cylinders are not communicated, of the outermost stage of flocculation chamber cylinder is communicated with the activated sludge chamber. The upper position, where two flocculation chamber cylinders are communicated, of the volume flocculation chamber is provided with a sludge discharging groove with a sludge discharging tube. The end, not communicated with the volume flocculation chamber, of the activated sludge chamber is externally connected with one or more concentrating chambers through one or more flow guiding tubes. A mud discharging chamber with a mud discharging tube is arranged at the bottom inside each concentrating chamber. An ultrafiltration film filter is arranged on the upper portion in each concentrating chamber, and the upper portion of each concentrating chamber is connected with a water outlet tube. The clarified ultrafiltration water processing device can effectively increase reaction volumes, prolong the reaction time, precisely control sludge backflow, and improve the effects of flocculation, sedimentation and filtering and the water processing amount.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a clarified ultrafiltration water treatment device. Background technique [0002] With the rapid development of the current social economy and the continuous improvement of people's living standards, urban and rural water consumption is gradually increasing. However, due to the massive discharge of industrial and agricultural wastewater, water pollution is becoming more and more serious. In response to the above situation, various water quality standards formulated by various countries are becoming increasingly strict. [0003] Clarification tanks that use the principle of contact flocculation to remove suspended solids in water began to be used in the world as early as the 1930s, and have become one of the main means of clarification and sedimentation in water plant design. Clarifiers have been used in my country since the early 1960s. Since the clarifier utilizes its own sludge bac...

AI Technical Summary

Problems solved by technology

Since the clarifier utilizes its own sludge backflow for reuse, and the mixed reaction flocculation and sedimentation are all completed in one tank, the formation occupies a small area and saves investment. Therefore, it is widely used in small and medium-sized town water plants in my country, but the current tank type is common. There are the following problems: the volume of the reaction chamber is small, the reaction time is short, and the return flow of sludge is difficult to control, which affects the contact and flocculation of the return sludge. In addition, the sedimentation efficiency is low, so the treatment effect is poor, and the amount of treated water is limited. It can no longer adapt to urban areas. Increased water demand and the need for higher water quality standards
