Problems solved by technology

Although it solves the problems of poor efficiency, poor continuous operation performance, and high treatment costs, when the SS of the influent is higher than 800mg / L, problems such as blockage and collapse will occur, and the SS of the effluent will increase accordingly, affecting the stable operation of the system

Embodiment 1

[0034] A high-efficiency contact anaerobic reactor, such as figure 1As shown, it includes an anaerobic reactor main body 1, the bottom of the anaerobic reactor main body 1 is provided with a water inlet pipe 2, and the anaerobic reactor main body 1 includes a reaction zone at the front end of the anaerobic reactor and a rear end The separation zone, the reaction zone and the separation zone are connected through the water passing zone 6, the reaction zone is composed of two reaction chambers connected in series, and each reaction chamber is provided with a mechanical stirring device 3 for separating waste water and anaerobic sewage The mud is stirred and mixed evenly, which is convenient for full reaction; the upper part of each reaction chamber is provided with a gas collection chamber 4, which is used to collect the biogas generated by anaerobic reaction; the two reaction chambers are separated by a retaining wall 5; the separation area is separated by The support 7 is provi...

Embodiment 2

[0038] A method utilizing the high-efficiency contact anaerobic reactor described in embodiment 1 to treat waste water, comprising steps as follows:

[0039] The wastewater to be treated enters the anaerobic reactor main body 1 through the water inlet pipe 2, and the reaction zone is provided with anaerobic sludge. The wastewater is stirred by the mechanical stirring device 3, so that the wastewater and the anaerobic sludge are evenly mixed with each other, and the anaerobic sludge The mud and the waste water are completely in contact, and the generated biogas rises and is collected in the gas collection chamber 4. The waste water passes from the water passing area 6 to the separation area at the rear end, and the sludge is concentrated in the primary mud collection area 8 through natural settlement, and is returned by the sludge pump 18. To the front end of the anaerobic reactor main body 1 or discharged to the sludge treatment system; the supernatant enters the built-in secon...

Embodiment 3

[0041] As described in Example 1, the difference is:

[0042] The packing 14 is an inclined tube, the material is polypropylene, the inclination angle is set to 75°, and the vertical height of the packing 14 is 1500mm.

Abstract

The invention relates to an efficient contact type anaerobic reactor and a method for treating wastewater, the reactor comprises an anaerobic reactor body, the anaerobic reactor body comprises a reaction zone located at the front end and a separation zone located at the rear end, the reaction zone and the separation zone are connected through a water passing zone, and the reaction zone is formed by connecting more than one reaction chamber in series; the separation zone is provided with a built-in secondary mud-water separation zone through a support, the lower part of the separation zone is provided with a primary mud collection zone, the lower part of the built-in secondary mud-water separation zone is provided with a secondary mud collection zone, and the side wall of the lower part of the built-in secondary mud-water separation zone is provided with a water distribution port; two support frames, a water outlet tank, a water outlet and a drainage tank are sequentially arranged at the upper part of the built-in secondary mud-water separation zone along the water outlet direction, a three-phase separator and a filler are arranged on the support frames, and the primary mud collection zone and the secondary mud collection zone are connected with a sludge pump. Inlet water SS is allowed in a large range, operation is easy, the adaptive capacity is high, operation is stable, and suspended solids in outlet water of the system can be greatly reduced.

Description

technical field [0001] The invention relates to a high-efficiency contact anaerobic reactor and a method for treating waste water, belonging to the technical field of environmental protection water treatment and purification. Background technique [0002] In recent years, with the gradual implementation of national environmental protection policies, industrial enterprises have gradually strengthened their investment in sewage treatment systems. Due to the relatively low per capita water consumption in our country, the cost of industrial water use is increasing year by year, and the requirements for sewage discharge are also constantly improving and becoming stricter. [0003] Affected by the waste paper import policy, most of the raw materials used by my country's waste paper pulping and papermaking enterprises are national waste. Domestic waste paper has been recycled for many times, resulting in poorer quality of raw materials; in the production process, in order to ensure...
