Sectional type anaerobic baffled reactor

Abstract

The invention belongs to sewage treatment device, in particular to waste water anaerobe treatment device with principal character of sectional water inlet operation. An anaerobic reaction chamber surrounds the main part of a reactor, the middle of the main part of the reactor is provided with a denitrification dephosphorization zone, the bottom is provided with a sludge settling zone which is externally connected with a sludge outlet pipe; the top is provided with an overflow groove which is externally connected with a water outlet pipe; the anaerobic reaction chamber is divided into a plurality of anaerobic reaction chambers by baffles, baffle plate positioned between two adjacent baffles divide each chamber into a lower water district and an upper water district, the top of the lower water district is provided with a water inlet pipe, the bottom of the upper water district is thrown in granular anaerobic sludge, the top is provided with a sewage sample port; a row of water discharging ports are arranged between the bottom of the anaerobic reaction chamber with the lowest height of the baffle and the sludge settling zone. The invention has the characteristics of very low energy consumption, high load resistance, small amount of excess sludge, good water conservancy mixing condition, easy devices, small floor area, low running cost and the like.

Description

technical field [0001] The invention belongs to sewage treatment equipment, in particular, it is a waste water anaerobic biological treatment equipment mainly characterized by segmented water inflow operation. Background technique [0002] Sewage treatment has become an important issue of environmental protection, and sewage treatment equipment is a key link in the process of sewage treatment. There are many existing sewage anaerobic treatment equipment, and wastewater anaerobic treatment equipment has a series of advantages in low operation cost, available energy (biogas) generation and treatment of high-concentration wastewater. However, existing wastewater anaerobic treatment equipment, such as the disclosed spiral plug flow drum anaerobic reactor (patent number: 200710047071.7), an anaerobic reactor for treating wastewater containing high-concentration suspended solids (patent number: 200410034141.1), An expanded granular sludge bed anaerobic reactor (patent number: 031...
