Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1

An industrial wastewater centralized treatment system, as shown in fig. 1, comprises: the

control device

11, 2 or 3 or 4 or other designs need the number of waste liquid buffer mechanisms. The waste liquid buffer mechanism comprises a waste liquid inlet pipe 1, a buffer pool 2 and a waste liquid discharge pipe 3 which are sequentially communicated. The waste liquid inlet pipe 1 is communicated with an enterprise sewage discharge pipe. The waste liquid discharge pipe 3 of each waste liquid buffer mechanism is communicated with a waste liquid header pipe 6. The outlet of the waste liquid header pipe 6 is communicated with the inlet of the waste liquid treatment device 7, and the discharge pipe 10 of the waste liquid treatment device 7 is communicated with external equipment. The external equipment may be secondary treatment equipment, a treated water recovery tank, or the like as needed.

As shown in fig. 2, the waste liquid inlet pipe 1 is communicated with the top of the buffer pool 2, and the waste liquid discharge pipe 3 is located at the opposite side of the waste liquid inlet pipe 1 and is communicated with the bottom of the buffer pool 2. And a first electric control electromagnetic valve 4 is arranged on the waste liquid discharge pipe 3.

As shown in fig. 1, 2 or 3 or 4 or other hoppers 8 with required number are arranged above the waste liquid treatment device 7. Each hopper 8 is communicated with the feed inlet of the waste liquid treatment device 7 through a feed pipe. Each charging pipe is provided with a second electric control electromagnetic valve 9.

As shown in fig. 1, the first electronically controlled solenoid valve 4 and the second electronically controlled solenoid valve 9 are respectively in signal connection with a signal output end of a control device 11. The control device 11 is a PC controller or a PLC controller. The signal connection is connected through a signal line or wirelessly connected through a local area network/4G network/5G network.

The working process of the system is that firstly, the waste liquid inlet pipes 1 communicated with the waste liquid inlet pipes 1 are numbered according to the types of production enterprises communicated with the waste liquid inlet pipes 1, corresponding water treatment reagents such as flocculating agents, buffering agents, acid-base reagents and the like are added into hoppers 8 with corresponding numbers, and meanwhile, the numbers are synchronously arranged in the first electric control electromagnetic valves 4 and the control device 11 corresponding to the waste liquid inlet pipes 1. Then, when the industrial enterprise discharges the waste liquid, the waste liquid firstly enters the buffer pool 2 through the waste liquid inlet pipe 1, and the buffer pool 2 plays a role in adjusting the water treatment progress of the part of industrial wastewater. That is, when the waste liquid treatment apparatus 7 is in a saturated operation state, the industrial waste water is temporarily stored in the buffer tank 2. When the waste liquid treatment device 7 is in an unsaturated working state, the control device 11 starts the corresponding first electronic control electromagnetic valve 4 on the waste liquid discharge pipe 3 of the buffer pool 2, and simultaneously starts the corresponding second electronic control electromagnetic valve 9 below the hopper 8. At this moment, the waste liquid in the buffer pool 2 enters the waste liquid treatment device 7 through the waste liquid header pipe 6, and the waste liquid treatment device 7 can treat the mixed liquid added with the waste water in the buffer pool 2 because the second electric control electromagnetic valve 9 of the corresponding hopper 8 is started. When the industrial enterprise stops sewage discharge, after the sewage in the corresponding buffer pool 2 completely flows into the waste liquid main pipe 6, the control device 11 controls the first electric control electromagnetic valve 4 and the second electric control electromagnetic valve 9 corresponding to the buffer pool 2 to be closed. In order to meet the requirement of circulation of waste liquid in each pipeline, a pump can be additionally arranged at the position required by the pipeline, for example, a water suction pump is additionally arranged on the waste liquid discharge pipe 3, a water suction pump is additionally arranged on the waste liquid header pipe 6, and the like.

The waste liquid header pipe 6 is provided with a second check valve 14 at a communication port of each waste liquid discharge pipe 3 at a position remote from the waste liquid treatment device 7. The first check valve 13 is used to prevent the waste liquid from flowing back to the waste liquid inlet pipe 1 when the buffer tank 2 is full. The second check valve 14 is used to prevent the waste liquid in the waste liquid header pipe 6 from flowing back to the waste liquid buffer mechanism away from the waste liquid treatment device 7 when the waste liquid buffer mechanism away from the waste liquid treatment device 7 stops operating.

Example 3

Based on the industrial wastewater centralized treatment system in the embodiment 1, as shown in fig. 1, the waste liquid discharge pipe 3 is provided with an electronic flow meter 5 between a first electrically controlled electromagnetic valve 4 and a waste liquid header pipe 6. The signal output end of the electronic flowmeter 5 is in signal connection with the signal input end of the control device 11. The additionally arranged electronic flowmeter can accurately know the flow of the wastewater in the buffer tank 2 entering the waste liquid header pipe 6, so that the control device 11 can accurately control the opening and closing degree of the second electric control electromagnetic valve 9 below the corresponding hopper 8, and the water treatment agent can accurately add different flows of wastewater.
