Embodiment 1

[0026] Such as figure 1 Shown is the flow chart of the bath wastewater treatment process embodiment of the present invention, the water treatment process of the present embodiment comprises the following steps:

[0027] (1) The bathing wastewater enters the adjustment pool through the grid, and a pH regulator is added to adjust the pH of the wastewater to neutral

[0028] (2) Neutral waste water flows into the filter tank in the regulating tank;

[0029] (3) The filtered wastewater flows into the flocculation tank, adding Al 2 o 3 Polymer and FeSO 4 , and compress the air, add defoamer, and pump water to the MBR reaction pool;

[0030] (4) After the wastewater is treated in the MBR reaction tank, it is injected into the disinfection tank for disinfection, and part of the purified water is circulated and sprayed above the MBR reaction tank;

[0031] ⑸ After disinfection, it becomes purified water, which can be used for bathing or drinking.

[0032] The following table is ...

Abstract

The invention discloses a bath water recycling MBR technology, and belongs to the technical field of reclaimed water recycling. The technology comprises the following steps: (1) introducing bath wastewater into a regulation tank by going through gratings, and adding a pH adjuster to neutralize the wastewater; (2) introducing the neutral wastewater in the regulation tank to a filtering tank; (3) introducing the filtered wastewater into a flocculation tank, adding a flocculating agent, compressing the air, and pumping the water to a MBR reaction tank; (4) processing wastewater in the MBR reaction tank, and injecting the wastewater into a disinfecting tank to disinfect the wastewater; (5) obtaining purified water after disinfection. The provided technology can effectively prevent sludge expansion and foam generation in the MBR reaction tank, the continuity and efficiency of the technology are both improved, the quality of the processed bath water is stable and good, and the processed water is accord with the national drinking water standards, can be used as drinking water, and is safe and harmless to human body. Moreover, the operation management is convenient, and the automatic control can be easily achieved.

Description

technical field [0001] The invention belongs to the technical field of reclaimed water reuse, and in particular relates to an MBR process for reusing bath water. Background technique [0002] Bathing water consumes a lot of water and has low pollution, which is a high-quality reused water source. Today, when water resources are extremely scarce and reuse of reclaimed water is increasingly valued, the reuse of bathing water has become an important issue. [0003] Compared with many traditional treatment processes, MBR has the advantages of high-quality and stable effluent quality, less residual sludge output, removal of ammonia nitrogen and refractory organic matter, and easy transformation from traditional processes. However, it has the disadvantages of high energy consumption, easy membrane fouling which brings inconvenience to operation and management, and high membrane cost, so it is necessary to carry out research and improvement.
