Problems solved by technology

The principle of the biofilm method is that the biofilm first adsorbs organic matter attached to the water layer, and is decomposed by the aerobic bacteria in the aerobic layer, and then enters the anaerobic layer for anaerobic decomposition, and the flowing water layer washes away the aged biofilm to Growth of new biofilm, and so on to achieve the purpose of purifying sewage, but this method requires highly dense aerobic bacteria, anaerobic bacteria, facultative bacteria, fungi, protozoa and algae to fully filter the sewage, and its operating cost very high
[0005] However, both of the above two methods have disadvantages such as high infrastructure and operating costs, cumbersome treatment process, and unstable effluent quality.

Embodiment 1

[0036] Such as figure 1 As shown, a construction waste aggregate sewage treatment system according to an embodiment of the present invention includes a water inlet device 1, the water inlet device 1 is a water pump, and the water inlet device 1 is connected to a primary sedimentation filter tank 2 arranged in series in sequence, at least one well Oxygen tank 5, secondary sedimentation filter tank 6 and water purification filter tank 7, water purification filter tank 7 is connected to water outlet device 8, and water outlet device 8 is a water outlet pipe, wherein the quantity of aerobic tank 5 can be appropriately adjusted according to the weight of sewage quality. increase or decrease.

[0037] Bio-aggregate 11 is filled in the aerobic tank 5, and bio-aggregate 11 comprises construction waste aggregate and the biofilm formed by the biological agent attached to its outside, and described construction waste aggregate comprises crushed stone, block stone, breccia, round Gravel,...

Embodiment 2

[0057] If there is a situation in which the metal element exceeds the standard in the sewage, the following structure is added on the basis of Example 1:

[0058] The aerobic pool 5 also includes an aerobic pool for removing metal elements. The aerobic pool for removing metal elements is filled with bio-aggregate for removing metal elements. For construction waste aggregate, the biological reagent for removing metal elements includes at least one of the following microorganisms, including Mycetobacillus, various yeasts, Desulfovibrio and other microorganisms that can remove metal elements in water by adsorption, so that the construction waste aggregate Microbial biofilms that can remove metal elements in water through adsorption, such as Mycobacillus biofilm, various yeast biofilms, and Desulfovibrio biofilms, are formed on the surface.

[0059] Principle of use:

[0060] Sewage enters into the primary sedimentation filter tank 2 by a pump and stands still. The insoluble matt...

Abstract

The invention relates to a building garbage aggregate sewage treatment system. The system comprises a water feeding device, the water feeding device is connected to a primary deposition filter tank, at least one aerobic tank, a secondary deposition filter tank and a water purification filter tank, the primary deposition filter tank, the at least one aerobic tank, the secondary deposition filter tank and the water purification filter tank are orderly connected in series, the water purification filter tank is connected to a water discharge device, the aerobic tank is filled with a biological aggregate, the biological aggregate comprises a building garbage aggregate and a biological film which adheres to the outer side of the building garbage aggregate and is formed from a biological agent, and an aeration pipe is arranged in the aerobic tank. A layer of high efficiency water purification microbes adhere to the surface of the building aggregate with good adsorption effects so that contact between the biological film and substances in water is greatly improved, organic matters, nitrogen and phosphor removal effects are good, product water quality is good, the product water satisfies surface water IV type standards and a part of the product water satisfies II type water standards.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an environment-friendly and low-energy consumption construction waste aggregate sewage treatment system. Background technique [0002] At present, my country's urban sewage is mainly treated through the construction of sewage treatment plants, and its conventional processes are activated sludge method and biofilm method. [0003] The basic technological process of activated sludge process consists of five parts: aeration tank, secondary settling tank, aeration system, sludge return and excess sludge discharge. Wastewater and returned activated sludge enter the aeration tank together to form a mixed solution, and aeration The air tank is a bioreactor, which is filled with air through the aeration equipment, and the oxygen in the air dissolves into the mixed liquid to produce an aerobic metabolic state, and then the mud-water mixture in the aeration tank flows into the secondary sed...
