Problems solved by technology

[0002] At present, the water outlets of various types of reactor production devices for treating wastewater are connected to the atmosphere. In the reactor, the granular sludge is sheared by the rapidly rising wastewater, which increases the number of small particles and reduces the amount of sludge. The contact area between the particles and the wastewater, and the suspended solids in the wastewater, will gradually decrease under the hydrostatic pressure with the increase of the rising height, causing a large loss of suspended solids and reducing the purification rate of the treated wastewater

Embodiment Construction

[0011] In Fig. 1, the pressure anaerobic bioreactor device [1] and the grid filter fine filter water outlet device [2] are two independent devices, which are connected by the outlet pipe [19], forming a waste water pressure anaerobic biological treatment The main body of the reactor assembly. The reactor shell [3] is a closed tower reactor with a large height-to-diameter ratio. The intermediate air seal [17] in the device separates the reactor device into a bottom reaction zone [7] and an upper reaction zone [8] Two units. In the reactor device, the double helix guide plate [10] is turned up along the inner wall of the shell, and forms two spiral guide chambers, the first guide chamber [11] and the second guide chamber [12]. With the air collecting hood [13] above, the water enters from the bottom of the reactor device with a pump, and under the distribution of the water distributor [27], the water flows in the spiral flow guide chamber in the way of turbulent flow and advect...

Abstract

The invention discloses a method for wastewater pressure anaerobic biological treatment and the reactor device. When treating wastewater, the wastewater-particle sludge contact time is prolonged and the wastewater to particle sludge shearing strength is decreased, which makes wastewater be mixed with particle sludge completely and large amount of organics convert to methane. Using pressure produced in biological metabolism, the suspension solid is filtered out at grid filtering layer, which make the quality of water outlet approach to definite purity, and the water inlet volume load factor of the reactor being improved substantially. And the produced methane also has definite pressure, being pressure methane.

Description

Technical field [0001] The invention relates to a method and device for anaerobic biological treatment of wastewater, in particular to a method and device for anaerobic biological treatment of wastewater under pressure. Background technique [0002] At present, the water outlets of various types of reactor production devices for treating wastewater are connected to the atmosphere. In the reactor, the granular sludge is sheared by the rapidly rising wastewater, which increases the number of small particles and reduces the amount of sludge. The contact area between the particles and the wastewater, and the suspended solids in the wastewater, are gradually reduced by the hydrostatic pressure as the rising height increases, causing a large loss of suspended solids and reducing the purification rate of the treated wastewater. Contents of the invention [0003] In order to increase the upflow velocity of the wastewater in the reactor, reduce the shear strength of the wastewater ...
