Anaerobic Sequencing Batch Reactor (ASBR)
Buried sewage treatment equipment manufacturers to deal with printing and dyeing wastewater treatment applications ASBR device, the use of DN400 UPVC pipe production, the bottom of the board and triangular support with PVC sheet with plastic welding rod welding, high 1200 mm, the effective volume of 120 L, the reactor side wall There are 10 holes with a diameter of 20 mm, with the bottom being the inlet (also venting), the top being the overflow port, the middle being the outlet, the rest being the sampling port, and the reactor running for one cycle Is 12 h, the sedimentation time is 2.5 h, the volume of each incoming and outgoing water is determined by the hydraulic retention time in the MBR pool, and the internal combustion (15 min per hour) is used to make the influent matrix and the sludge in the reactor Fully mixed, the reaction of the various stages of time by the PLC to control.
Membrane bioreactor (MBR)
The MBR of the buried sewage treatment equipment is made of plexiglass with a size of 550 mm × 300 mm × 500 mm, a normal liquid level of 420 mm, an effective volume of 65 L, and a flat sand at the bottom Head, by a blower gas supply, with a gas flow meter to control its gas flow, continuous aeration, which is directly above the hollow fiber membrane components. In addition, the reactor is equipped with air backwashing and replenishing device, air backwash can slow down the membrane pollution, and replenishment device can be in the backwash after the end of the connection membrane UPVC cavity filled with water so that the pump can be smoothly water.
The reaction device is running
Buried sewage treatment equipment manufacturers design of the reaction device is divided into two groups (ie S1 and S2), mainly used to deal with a textile company sewage treatment plant secondary effluent.
Inoculate sludge
For the ASBR plant, the sludge is in the aerobic biochemical pool of the WWTP, which is airtight for 10 days and the supernatant is discarded. The sludge is concentrated and moved into the reactor, then the water is introduced and the test is started. Water quality indicators; for the MBR device, inoculation of sludge from the same from a sewage treatment plant aerobic biochemical pool, the Jingjing discarded supernatant after the sludge concentration into the reactor, boring exposure 24 hours and then directly Raw water for sludge domestication culture, and began to detect into and out of the water quality indicators.
Water quality
The water quality is 200 ~ 300 mg / L, pH 6.8 ~ 7.1, and the color is 200 ~ 260 times.
Analytical method
The effluent of ASBR supernatant, MBR supernatant and membrane effluent were measured during the test, including COD, chroma, pH, iron salt, hardness and so on. Wherein the supernatant water quality is a filtrate obtained by filtering the mixed liquid in the reactor with a qualitative filter paper. The standard method of "water and wastewater monitoring and analysis method" is adopted for each measurement project and analysis method.
