Example Embodiment
[0032] Example 1
[0033] Such as Figure 1~6 As shown, the present invention provides a coal gasification wastewater treatment device, including a primary biofilm reactor 1 and a secondary biofilm reactor, the primary biofilm reactor 1 includes:
[0034] The housing 101 has a hollow cavity inside;
[0035] An aeration device, which is composed of a gas pipe 102, a gas regulating valve 103, and an air pump 104. The first part of the gas pipe 102 is located at the bottom of the housing 101, and the first part of the gas pipe 102 consists of a circular ring and is arranged in the ring It is composed of a circle of rice-shaped branch pipes;
[0036] Suspended filler 105, which is filled in the housing 101 and occupies 65% of the volume of the cavity of the housing 101, and is located above the trachea 102;
[0037] The desliming element includes a main brace 106, a supporting rod 107, a desliming net 108 and a pulling member. The supporting rod 107 is arranged in 2 groups along the axis ...
Example Embodiment
[0052] Example 2
[0053] The first-level biofilm reactor and the second-level biofilm reactor of Example 1 are used to treat coal gasification wastewater. The parameters of coal gasification wastewater before treatment are COD of 1000mg / L, ammonia nitrogen of 310mg / L, and volatile phenol ≤185mg / L. The pH value is 7.4, the COD removal rate of the treated coal gasification wastewater is 89.2%, the ammonia nitrogen removal rate is 96.4%, and the volatile phenol removal rate is 99.2%.
