Embodiment 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, and the primary biofilm reactor 1 includes:

[0034] The housing 101 has a hollow cavity inside;

[0035] The aeration device 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 is formed by a ring and is arranged in the ring. The rice-shaped branch pipe of the circle is formed;

[0036] Suspended filler 105, which is filled in the casing 101, and accounts for 65% of the volume of the cavity of the casing 101, and is located above the air pipe 102;

[0037] The desilting parts include main support rods 106, support rods 107, desilting nets 108 and pullers. The support rods 107 are arranged in two groups along the axis of the main support rods 106...

Embodiment 2

[0053] The first-level biofilm reactor and the second-level biofilm reactor of Example 1 are used to process coal gasification wastewater. The parameters of coal gasification wastewater before treatment are 1000mg / L for COD, 310mg / L for ammonia nitrogen, 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%.

Abstract

The invention discloses a coal gasification wastewater treatment device, which comprises a primary biofilm reactor and a secondary biofilm reactor. The primary biofilm reactor comprises: a shell with a hollow cavity inside; , a gas regulating valve, and an air pump. The first part of the air pipe is located at the bottom of the housing, and the first part of the air pipe is composed of a ring and a rice-shaped branch pipe arranged on the inner ring of the ring; suspended filler, which is filled in the shell body, and account for 65% of the volume of the housing cavity, and is located above the trachea. The invention solves the problems that the existing coal gasification wastewater treatment device occupies a large area and has low removal efficiency.

Description

technical field [0001] The invention relates to the field of coal gasification wastewater treatment. More specifically, the present invention relates to a coal gasification wastewater treatment device. Background technique [0002] Coal gasification occupies an important position in my country's energy and chemical industry, but wastewater treatment has become a key issue restricting the development of this industry. The quality of the waste water produced by the three gasification processes of fixed bed, fluidized bed and entrained bed is not the same, but the common feature is the high content of ammonia nitrogen and COD. At home and abroad, the process routes of pretreatment, biological treatment and advanced treatment are generally used to treat coal gasification wastewater. The removal of ammoniacal nitrogen and COD is mainly realized in the biological treatment unit, and the existing biological treatment process is basically based on the activated sludge method. Nitr...
