Problems solved by technology

[0023] However, due to the complex geological structure, when the injected air encounters a complete rock formation zone, a loose broken zone or a curved deformation zone, it is difficult for the injected air carrying volatile organic compounds to penetrate the above-mentioned geological structure, and when the injected air meets the above-mentioned geological structure, the air Large resistance will greatly increase the energy consumption of the equipment
It is even less effective for pollutants that are neither volatile nor biodegradable

Embodiment 1

[0051] Such as figure 2 As shown, the three-dimensional schematic diagram of the 1,2-dichloropropane treatment system provided by the present invention can be seen, including the bottom containing the shock surge pool 8 and the top with the spray nozzle 3, wherein the inside of the shock surge pool 8 The installation is divided into multiple oscillating surge corridors by multiple partitions 12, and the multiple oscillating surge corridors are arranged in parallel and misplaced, and connected from head to tail to form an S-shaped channel. One end of each oscillating surge channel is provided with an oscillating surge device, which is composed of a oscillating surge plate 10 and a reciprocating rod 11 slidingly connected; Water outlet pipe 7 is provided.

[0052] The top spray system is connected with the bottom oscillating surge pool 8 through the return pipe 5 arranged on the side of the outlet pipe 7 at the bottom of the oscillating surge pool 8, and the water that reaches...

Embodiment 2

[0067] In order to test the rationality of the design and make it achieve the best treatment effect, the 1,2-dichloropropane removal rate test and the influencing factors were carried out through the above 1,2-dichloropropane separation system. The test results are as follows:

[0068] 1. The effect of the stroke of the oscillating surge plate on the removal of 1,2-dichloropropane

[0069] In the simulated 1,2-dichloropropane separation system, add 1,2-dichloropropane at a concentration of 100 μg / L, control the stroke of the oscillating surge plate in the simulated system to 400mm, 500mm, and 600mm, and record the travel conditions of each oscillating surge plate, 1 , 2-dichloropropane removal rate, such as Figure 6As shown, it is the characteristic curve of the removal of 1,2-dichloropropane by the above system, and the change curve of 1,2-dichloropropane removal rate and time reflects and expresses the removal rate and time of 1,2-dichloropropane relation. Wherein the ve...

Abstract

The invention discloses a 1,2-dichloropropane separation system and separation technique. The separation system comprises a bottom with vibration surge tanks and a top with a nozzle head, wherein a water channel is divided into the plurality of vibration surge tanks by the tank body. The separation technique is implemented in a way that: under the action of the vibration surge tanks, 1,2-dichloropropane-containing underground water flows according to a S-shaped route; the reflux quantity is controlled at 80 m<3> / minute, the water level is controlled at 80cm, the vibration surge period is controlled at 20 times / minute, and the vibration surge plate stroke is controlled at 600mm; and a continuous spray mode is adopted. The separation technique has the characteristics of high environment friendliness, high resource utilization ratio, high treatment effect and high impact resistance, and implements full-automatic control.

Description

technical field [0001] The invention belongs to an environmental protection treatment technology, relates to the field of treatment of groundwater containing 1,2-dichloropropane, in particular to a 1,2-dichloropropane separation system and a separation process thereof. Background technique [0002] 1,2-chloropropane (ClCH 2 CHClCH 3 ) is a synthetic low-boiling organic chlorinated hydrocarbon substance, which is a colorless liquid with a chloroform-like odor. Relative density (water = 1) 1.16, refractive index 1.4388, molecular weight 112.99, vapor pressure 5.33kPa, slightly soluble in water, easily soluble in ether, miscible with most organic solvents. At 20°C, the solubility of 1,2-chloropropane in water is 0.26% (by weight), and the azeotropic point of the binary azeotrope of 1,2-chloropropane (1,2-chloropropane is 89.6%) containing water is 78.4°C. [0003] The vadose zone is an important channel connecting the surface soil and the aquifer, and plays a certain "barri...
