MBBR adn MBR integrated sewage treatment equipment

Abstract

The invention relates to MBBR and MBR integrated sewage treatment equipment. The equipment comprises a cylinder body, a water inlet pipe and a water outlet pipe, the inner cavity of the cylinder bodyis divided into four compartments by three vertical compartment plates; the four compartments are an anaerobic zone, an anoxic zone, an aerobic membrane treatment zone and an equipment zone in sequence; the anaerobic zone, the anoxic zone and the aerobic membrane treatment zone communicate with each other through water passing holes in the compartment plates; the water inlet pipe communicates withthe upper part of the anaerobic zone; a mBBR carrier is added into the anaerobic zone, the anoxic zone and the aerobic membrane treatment zone; the anaerobic zone is provided with a stirring device,the bottom of the anoxic zone is provided with a plurality of aeration devices, the aerobic membrane treatment zone is provided with an integrated MBR membrane micro-power bioreactor, and a mixed liquid backflow device communicates with the aerobic membrane treatment zone and the anoxic zone; and the equipment zone is provided with a fan, a suction pump and an electrical cabinet. An anaerobic zone, an anoxic zone, an aerobic zone and a membrane treatment zone in a biochemical system are effectively integrated, the occupied area is small, the sewage treatment efficiency is high, and economicalefficiency and practicability are achieved.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to an MBBR+MBR integrated sewage treatment equipment. Background technique [0002] In the village and town sewage treatment equipment in the prior art, the equipment casing is generally made of carbon steel or glass fiber reinforced plastic. The carbon steel casing: the cost of raw materials is high, and the thickness is only 8-15mm. Moreover, due to the certain corrosiveness of sewage, it is often It will lead to corrosion and rust of the carbon steel shell, short service life, and requires a lot of manpower and material resources to maintain the equipment regularly. Shell made of FRP: The production environment of raw materials is poor, and the odor and dust produced will cause harm to the human body and the environment. Some provinces and cities have issued documents to prohibit the production of FRP materials. In addition, once FRP products are discarded, they cannot...

Problems solved by technology

[0002] In the village and town sewage treatment equipment in the prior art, the equipment casing is generally made of carbon steel or glass fiber reinforced plastic. The carbon steel casing: the cost of raw materials is high, and the thickness is only 8-15mm. Moreover, due to the certain corrosiveness of sewage, it is often It will lead to corrosion and rust of the carbon steel shell, short service life, and requires a lot of manpower and material resources to maintain the equipment regularly

Shell made of FRP: The production environment of the raw materials is poor, and the odor and dust produced will cause harm to the human body and the environment. Some provinces and cities have issued documents to prohibit the production of FRP materials. In addition, once FRP products are discarded, they cannot be effectively recycled, and often they can only be discarded. Land burial will cause secondary pollution to the soil environment

Moreover, the thickness of the shell is generally 2-3cm, which has no thermal insulation effect and cannot effectively adapt to the cold environment in the north.

[0003] Traditional biological treatment technologies usually have secondary sedimentation tanks and advanced treatment processes at the end, which greatly increases the footprint of sewage treatment facilities

In addition, in the process of sewage treatment, many equipment need to manually add carbon sources to ensure the efficiency of decarbonization and phosphorus removal, which increases the operating cost
