A reaction pool that is used in the mbr system to remove phosphorus efficiently and recover degradation products

Abstract

The invention relates to the technical field of sewage treatment, in particular to a reaction pool used in an MBR system for efficient phosphorus removal and capable of recovering degraded products, which includes impurity removal equipment installed at a top corner of the reaction pool, and phosphorus removal equipment installed inside the reaction pool The recovery equipment below the equipment and its phosphorus removal equipment, the inside of the reaction tank and near the impurity removal equipment are installed with aeration equipment and several bacteria rods installed directly in front of the aeration equipment, and the recovery equipment includes sliding at the bottom of the reaction tank. Shovel board. The invention intercepts large-volume floating objects through impurity removal equipment, reduces the pressure of membrane module purification in the MBR system, improves the phosphorus removal ability, and evenly blows the phosphorus removal bacteria in the bacteria rod through the set aeration equipment Attached to the attachment sheet in the reaction tank, and then the sewage is fully dephosphorized, degraded and precipitated, which is convenient for the efficient and rapid treatment of the sewage in the reaction tank, and all the degraded sediments are removed through the recovery equipment at the bottom of the reaction tank.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a reaction pool applied to an MBR system for highly efficient phosphorus removal and capable of recovering degraded products. Background technique [0002] Both industrial phosphorus-containing wastewater and phosphorus-containing fertilizer factory wastewater contain a large amount of phosphorus. In addition, because phosphorus-containing washing powder is commonly used in daily life, domestic sewage often contains a large amount of phosphorus. The discharge of these sewage into river water will cause excessive algae reproduction. It leads to eutrophication of water bodies and deteriorates water quality. The eutrophication of the water body will not only lead to the rapid growth of algae in the water, but also cause a sharp drop in the oxygen content of the water body, affecting the survival of aquatic organisms such as fish. Existing MBR, also known as membrane biorea...

[0002] Both industrial phosphorus-containing wastewater and phosphorus-containing fertilizer factory wastewater contain a large amount of phosphorus. In addition, because phosphorus-containing washing powder is commonly used in daily life, domestic sewage often contains a large amount of phosphorus. The discharge of these sewage into river water will cause excessive algae reproduction. lead to eutrophication of the water body and deteriorate the water quality

The eutrophication of the water body will not only lead to the overgrowth of algae in the water, but also cause a sharp drop in the oxygen content of the water body, affecting the survival of aquatic organisms such as fish

Existing MBR, also known as membrane bioreactor, filters phosphorus-containing sewage through the pore size of its own membrane and degrades it through microorganisms. Due to its large filtration ratio, the filtration cycle is shortened, and maintenance and cleaning are required, which consumes man-hours and manpower. In addition, the sediment at the bottom of the reactor is often sucked by a water pump, which is difficult to eradicate the sediment in the entire bottom surface
