Embodiment 1

[0066]The equipment of this embodiment includes a rack 1 , a water inlet tank 2 , a submerged ultrafiltration membrane group 3 , a membrane pump 4 , a reverse osmosis membrane group 5 , an automatic control system 6 , a membrane maintenance system 7 and a pure water tank 8 . The frame 1 includes a base plate (not shown in the figure) and a mounting frame (not shown in the figure); the base plate is provided with a water inlet tank 2 , a membrane pump 4 , a reverse osmosis membrane group 5 and an automatic control system 6 . The water inlet 2 is provided with a water inlet 21, a water return port 22 and a concentrated water inlet 23; the water inlet 21 is used to connect the reclaimed water, and the water return port 22 is used to return the concentrated water filtered by the submerged ultrafiltration membrane group to the original reclaimed water system, the concentrated water inlet 23 is used to connect the concentrated water of the reverse osmosis membrane. The submerged ult...

Embodiment 2

[0072] The equipment of this embodiment is substantially the same as the equipment of Embodiment 1, except that the reverse osmosis membrane group 5 is composed of a single-stage reverse osmosis membrane.

[0073] This embodiment is used for the reuse of reclaimed water in the treatment of printing and dyeing wastewater. The wastewater is alkaline wastewater, which has been pretreated by alkali recovery, neutralization, flocculation, sedimentation, biochemistry, sedimentation, etc., and has reached the discharge standard. In order to reduce wastewater discharge, All to be reused.

[0074] The supernatant liquid from the pretreatment sedimentation tank is connected to the equipment, and enters the water inlet tank 2 through the water inlet interface 21. Under the program control of the automatic control system 6, the membrane pump 4 is used as the power to make the reclaimed water pass through the submerged supernatant. The filter membrane group 3 and the reverse osmosis membra...

Embodiment 3

[0078] The equipment of this embodiment is basically the same as the equipment of Embodiment 1, except that the reverse osmosis membrane group 5 is composed of two-stage reverse osmosis membranes connected in series.

[0079] This embodiment is used for reuse of reclaimed water in landfill leachate treatment. Landfill leachate is a kind of high-concentration organic wastewater with complex components, which has been pretreated by biochemical and precipitation; If the discharge cannot meet the standard, it is planned to be reused.

[0080] The supernatant liquid from the pretreatment sedimentation tank is connected to the equipment, and enters the water inlet tank 2 through the water inlet interface 21. Under the program control of the automatic control system 6, the membrane pump 4 is used as the power to make the reclaimed water pass through the submerged supernatant. The filter membrane group 3 and the reverse osmosis membrane group 5 separate various impurities, upgrade the...

Abstract

The invention provides a reclaimed water recycling intelligent integrated device capable of implementing zero sewage discharge and application thereof, belonging to the technical field of reclaimed water recycling devices. The device comprises a water inlet tank, an immersed ultrafiltration membrane set, a pump for membranes, a reverse osmosis membrane set, an automatic control system, a membrane maintenance system and a pure water tank, wherein the water inlet tank, immersed ultrafiltration membrane, pump for membranes, reverse osmosis membrane set, membrane maintenance system and pure water tank are controlled by the automatic control system. The device is suitable for recycling various types of wastewater which can or can not be discharged after reaching the standard after pretreatment, is an integrated set capable of direct road transportation and is provided with the full-automatic control system, and the physicochemical indexes of the treated effluent water reach pure water indexes for general industry, thereby guiding the enterprise not to discharge wastewater any more and implementing zero wastewater discharge in deed.

Description

technical field [0001] The invention relates to the technical field of reclaimed water reuse equipment, in particular to an intelligent integrated equipment for reclaimed water reuse that realizes zero discharge of sewage and its application. Background technique [0002] Reclaimed water refers to non-drinking water that can be reused in industrial, living, municipal, environmental, etc. after various drainages have been treated to meet the specified water quality standards. Reclaimed water recycling is an important method of recycling wastewater, which can not only reduce the pollution of wastewater to the environment, but also reuse water resources. [0003] The traditional sewage treatment system aims to meet the discharge standards: sewage treatment is to treat the polluted wastewater through a certain process to make it meet the national discharge standards (so-called "standard discharge"); in fact, "standard discharge" Still polluting the environment. [0004] Due to...
