Embodiment Construction

[0007] As can be seen from the process flow chart in Figure 1, this laundry room sewage reuse process uses tap water as rinsing water to enter the washing machine for pre-washing or adding detergent for washing, and then these pre-wash and rinsing water are transported to the circulating water In the tank, the pre-wash water and rinsing water in the circulating water tank are sent to the ceramic membrane filtration system for filtration by pump pressure. The inorganic ceramic membrane separation technology used is material separation based on the sieving effect of the porous ceramic medium. Technology, it uses a dynamic cross-flow filtration method, that is, driven by pressure, the raw material liquid flows at a certain flow rate on the inner membrane surface of the membrane tube at a high speed, and the small molecule substance (liquid) penetrates the microporous membrane along the vertical direction. , While the macromolecular substances or solid particles are retained by the me...

Abstract

The present invention discloses a laundry sewage recovery and reutilization process. It is characterized by that said process adopts inorganic ceramic membrane separation technique and dynamic cross-flowing filtration mode to implement heat energy recovery, sewage recovery and detergent recovery so as to make the laundry sewage be changed into useful resource.

Description

Technical field [0001] The present invention relates to an improvement of a laundry room sewage recycling process, which can be applied to laundry rooms of railways, hotels, guesthouses, hospitals, saunas or social laundry rooms. technical background [0002] Since the laundry industry is a water-consuming and energy-intensive industry, with the rapid development of the laundry business, the sewage discharged from the laundry room is increasing day by day, and its cost has been high. Therefore, some people have proposed improvements in related technologies. For example, China Patent No. CN200510029068.3 on "Railway Washing Wastewater Reuse Method" proposes the following steps: (1) The laundry washing sewage passes through the grid to remove the suspended matter in the sewage and then enters the anaerobic hydrolysis tank; (2), through the grid The effluent enters the anaerobic hydrolysis and acidification tank, and the anaerobic activated sludge hydrolyzes and acidifies the macrom...
