Benefits of technology

This new technology allows for effective use of treated wastewater by combining both methods together through specialized equipment called grids or bags made from materials like charcoal (char), wood chips, rubber tires, plastic foam strips, etc., along with other substances such as sand particles, iron powder, lime water, cement clay, cerium oxide, calcium carbonate, magnesia). These combined treatments improve the effectiveness of these systems while reducing their negative side-effects associated therewith.

Problems solved by technology

Technological Problem: Current methods such as activated Sludge Method (ASM) or BioFilm Processing System (BFS), have limitations when treating heavily contaminating environments like China’s sewer system due to their complexity and expensive equipment needed.

specific Embodiment approach

[0022] The invention is a novel sewage treatment reaction device combining activated sludge method and biofilm method.

[0023] The test device is a cylindrical reactor made of plexiglass, with an inner diameter of 200mm, a height of 1.0m, and a total volume of 15L. The reactor cylinder is provided with a sampling port every 100mm. First, install a microporous aeration device at the bottom of the reactor. The aeration device is a sand table aeration disc with a diameter of 200 mm, which is the same as the inner diameter of the reactor. A circular plexiglass plate with fine holes is placed above the aeration disc to make the bottom of the reaction device Flat, uniform gas distribution throughout the reactor. Then encircle the fine grid into a column shape with a diameter of 140 mm, and fix it inside the reactor with a connecting bolt, parallel to the inner wall of the reactor. The aperture of the grid is 3 mm to prevent the filler from penetrating through the grid. Finally, the b

Abstract

The invention provides a sewage treatment reaction device in combination of the activated-sludge method and the biofilm method. The sewage treatment reaction device comprises a plurality of grid screens, biocarrier film filler, a connecting and fixing bolt, an organic glass disk with pores, and an aeration disk device. The sewage treatment reaction device is characterized in that firstly, an aeration device is mounted at the bottom part of a reactor, and the organic glass disk with the pores are mounted above the aeration device; the bottom part of the reactor is kept flat so as to ensure uniform aeration; secondly, the connecting and fixing bolt is fixed to the inner wall of the reactor through the grid screens, a 2 to 4cm clearance is reserved between the connecting and fixing bolt and the inner wall of the reactor and filled with the biocarrier film filler, and thus the activated sludge can be attached to the filler and grow to form a biofilm; an activated sludge reaction area is formed in the middle part; and the aeration device enables the sludge to be uniformly mixed. According to the sewage treatment reaction device, the grid screen filler introduced enables the activated-sludge method and the biofilm method to be combined, thus microorganism can be attached and grow well to form an aerobic area which can coexist with an anaerobic anoxic area, and as a result, the sludge treatment load can be greatly increased.
