Embodiment 1

[0028] Embodiment 1: self-circulation anaerobic reactor to the removal rate of COD

[0029] The most important indicator of organic pollutants in wastewater is COD, and the self-circulating anaerobic reactor should have a high removal effect on COD in wastewater. The molasses alcohol wastewater was taken from Xinjiang Changji Sugar Factory and was dark brown. The COD concentration of wastewater is 107900mg / L, the sulfate concentration is 1742mg / L, the chromaticity is 2000 times, and the pH is 4.67. The first stage: the influent COD concentration is 5000~6000mg / L, and the volume load is controlled by adjusting the influent flow rate, from 4~5kgCOD / m 3 d Gradually increase the load, and the volumetric load reaches 10kgCOD / m at the end of the first stage 3 d; the second stage: the influent COD concentration is about 10000mg / L, and the volume load is 10-20kgCOD / m 3 d; the third stage: the influent COD concentration is about 20000mg / L, and the volume load is 20-40kgCOD / m 3 d; t...

Embodiment 2

[0032] Example 2: Components of biogas produced by self-circulating anaerobic reactor

[0033] Using the molasses alcohol waste water inflow from Changji Sugar Factory in Xinjiang, the methane content in the produced gas is always above 70% (Table 1). When the influent concentration reaches 30000mg / L, the methane content reaches 83.67%. High-quality biogas.

Abstract

This invention relates to a biogas production wastewater treatment device and a cycle anaerobic reactor used in the device, which is used for environmental engineering. The device invented consists of a new self-cycle anaerobic reactor and a computer control system. The core self-cycle anaerobic reactor comprises two overlapping anaerobic reaction zones in series, wherein the upper parts of the two reaction zone are established gas-solid-liquid three phase separators respectively. The lower reaction zone is at an extreme high load, while the upper reaction zone is at low load. The three-phase separator sludge can be separated and returned to the main separator by the separator and biogas is collected. Internal reactor is capable of forming self-circle liquid, and can strengthen mass transfer process of organism and granular sludge and improve handling capability. The floor place of the three phase separator is small, high concentration of organic wastewater can be treated and biogas as biological energy can be produced. The device can achieve the scale biogas technology and automated production, and is an ideal scale wastewater treatment and gas production equipment.

Description

technical field [0001] A waste water treatment device for biogas production and a self-circulating anaerobic reactor used in the device. Specifically, it is a self-circulating anaerobic biological reaction device capable of treating various organic waste water and generating biogas. Background technique [0002] Since the reform and opening up, my country's economy has achieved unprecedented sustained high-speed growth. However, due to the rapid expansion of resource development and the rapid growth of energy consumption, my country's ecological damage and environmental pollution have reached a very serious level, and energy issues have also become constraints. Factors that cannot be ignored in economic development. In order to realize the sustainable development of our country's economy and society, we must resolve the contradiction between development and environmental protection. [0003] Anaerobic bioreactors can not only effectively treat organic wastewater, but also g...
