Quick startup device of annamox in low-temperature environment

Abstract

The invention relates to the technical field of water treatment, in particular to a quick startup device of annamox in low-temperature environment, which decreases the concentration of pollutants in intra-chamber wastewater, quickens cultivation progress of anaerobic sludge particles and reduces service limits, and which allows the pH of the intra-chamber wastewater to be smoothly adjusted so thatpracticality is improved. The quick startup device of annamox in low-temperature environment comprises a treatment tank, a collection hopper, a discharge pipe, a discharge pipe valve, anaerobic sludge particles, an inflow pipe, an inflow pipe valve, a sludge adjusting pump, a drain pipe and a three-phase separator; a chamber is arranged in the treatment tank. The quick startup device also comprises a mounting plate, a circulating pump, an auxiliary treatment tank, four groups of connection rods, a first motor, a first auxiliary pipe, a second auxiliary pipe, and a first auxiliary pipe; the left end of the mounting plate is connected with the bottom of the right end of the treatment tank. The quick startup device also comprises a buffer tank, a second motor, a transmission shaft, mixing rods, a water pump, a first water pipe and a second water pipe; a working cavity is arranged in the buffer tank; the left side of the top end of the buffer tank is provided with a feeding port.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a quick start-up device for anaerobic ammonium oxidation in a low temperature environment. Background technique [0002] As we all know, the low-temperature environment anammox quick-start device is an auxiliary device for quickly starting anammox, which has been widely used in the field of water treatment; the existing low-temperature environment anammox quick-start The device includes a treatment box, a collection bucket, a downpipe, a downpipe valve, anaerobic sludge particles, a water inlet pipe, a water inlet pipe valve, a sludge regulating pump, a drain pipe, and a three-phase separator. The inside of the treatment box is provided with a cavity chamber, the bottom of the treatment box is provided with a lower discharge port, and the lower discharge port communicates with the chamber, the bottom of the lower discharge port is connected with a collection bucket, and t...

[0002] As we all know, the low-temperature environment anammox quick-start device is an auxiliary device for quickly starting anammox, which has been widely used in the field of water treatment; the existing low-temperature environment anammox quick-start The device includes a treatment box, a collection bucket, a downpipe, a downpipe valve, anaerobic sludge particles, a water inlet pipe, a water inlet pipe valve, a sludge regulating pump, a drain pipe, and a three-phase separator. The inside of the treatment box is provided with a cavity chamber, the bottom of the treatment box is provided with a lower discharge port, and the lower discharge port communicates with the chamber, the bottom of the lower discharge port is connected with a collection bucket, and the output end of the bottom of the collection bucket is connected with a lower discharge pipe, and the upper discharge pipe is connected There is a downpipe valve, the lower half of the chamber is provided with anaerobic sludge particles, the left end of the water inlet pipe is closed, the left end of the water inlet pipe passes through the lower side of the right end of the treatment tank and extends into the chamber, the water inlet pipe The bottom of the chamber is provided with multiple groups of water holes, and the multiple groups of water holes communicate with the inside of the water inlet pipe, and the multiple groups of water holes are located inside the chamber, the water inlet pipe is provided with a water inlet valve, and the water inlet pipe The valve is located outside the right end of the treatment tank. The right input end of the sludge regulating pump passes through the middle of the left end of the treatment tank and extends into the chamber. The right input end of the drain pipe passes through the upper side of the left end of the treatment tank and extends into the chamber. The three-phase separator is located inside the chamber and below the drain pipe. The top output end of the three-phase separator is connected with an exhaust pipe, and the top output end of the exhaust pipe passes through the top of the treatment box. The middle part and extend to the outside of the top of the treatment box; when the existing low-temperature environment anaerobic ammonium oxidation quick start device is used, first open the valve of the water inlet pipe and close the valve of the lower discharge pipe, and then connect the water inlet pipe to the external water delivery device to the chamber The sewage is transported, and then the sewage is transported to the bottom of the chamber through the water inlet pipe and flows through the anaerobic sludge particles. The sewage passes through the anaerobic sludge particles and cultivates the anaerobic sludge particles. The sludge regulating pump is used to Adjust the sludge height, then the sewage passes through the three-phase separator, the gas in the water is discharged to the outside through the exhaust pipe, and then the treated water is transported to the outside through the drain pipe; the existing low-temperature environment anaerobic ammonia oxidation quick start device During use, it is found that when there are many pollutants in the sewage, it is easy to affect the cultivation progress of anaerobic sludge particles, resulting in high use limitations; and the pH of the sewage in the chamber is difficult to be adjusted smoothly, resulting in poor practicability
