Washing waste plastic sewage hazard case:
Residents living in Yongning Town, Pukou District, Nanjing, have reported that in recent times, as the weather gradually warmed up, the joint community of a small ditch constantly emitting a foul odor. Residents said that before this small ditch can be panned rice and wash vegetables, since there are several small processing plant stationed in their community, the wastewater produced without any treatment is directly discharged into the small river, polluting the environment.
The wastewater is discharged directly into the river ditch near the plant.
Under the guidance of Mr. Liu, a resident, the reporter followed the river all the way upstream to look for, after walking about 500 meters, to see the polluting enterprises, as Mr. Liu said, the plants of these enterprises are linked together, stretching for several kilometers. And in the back of these enterprises plant, saw a drainage ditch connected to the river, while every roughly 50 meters, there will be a drain pipe from the plant out, a steady stream of sewage from the plant.
Subsequently, the reporter went into two factories to check, in a plastic pellet factory to see, the entire plant is stacked with a large number of plastic particles have been processed, and the scene of a worker is using water to clean the machine, and these black wastewater is directly through the plant through a water pipe discharged to the back of the house of the drainage ditch. The owner of the plastic granule factory said that he has been doing this for more than half a year. It has always been drained in this way. In another plastic products factory, workers were grinding spoons that had just been produced, and the dust generated by the grinding was discharged directly outside the factory through two huge exhaust fans, without any treatment. The person in charge of this enterprise said, they are the local community investment over, plant are provided by the community, they pay rent.
After receiving the environmental problems reflected by the residents, staff from the Pukou District Environmental Protection Bureau and Yongning Township rushed to the scene and took photos and evidence. Law enforcement officials said that the current inspection to see that all the outfalls are required to close all the enterprises to immediately stop discharging, the next step will be to centralize the pipeline to the outside world. Law enforcement officials also found that this piece of plant inside no heavy metal pollution enterprises, are some processing enterprises, for the polluted river water, law enforcement officials also took samples, taken back for further testing. For the current has been polluted sewage in the river ditch, the jurisdiction of the government departments also said it will be thoroughly cleaned up.
Introduction of waste plastic sludge treatment equipment:
LWJ decanter centrifuge (solid-liquid separator):
1, with a compact structure, in the same processing capacity of the machine's small size, light weight, relatively convenient to move;
2, large capacity, good separation performance, wide range of applications;
3, high solid phase recovery rate
3, high solid phase recovery rate, low running cost, no filter cloth;
4, automatic continuous operation, operation, simple use, easy installation and maintenance and other advantages. It has been widely used in many industrial and mining fields such as geology and minerals, petroleum, chemical industry, metallurgy, pharmacy and environmental protection.
Performance characteristics of sludge treatment equipment for cleaning waste plastic bags:
The main parts are made of high quality carbon steel or stainless steel. The pusher adopts special wear-resistant measures, can be set with carbide wear-resistant tile or surfacing carbide protective layer. Adopt cycloid differential, low noise, strong bearing capacity.
1. Compact structure of a single machine, occupies an area of 2-3 square meters, running smoothly. It can unload automatically and operate continuously, and workers only need to operate the power cabinet, which is clean and hygienic.
2. Wide adaptability to the material, can be separated from a wide range of solid-phase particle size (0.005 ~ 2mm), in the solid-phase particle size is not uniform when the separation can be carried out as usual. Dosing depends on the material, generally do not need to add drugs, cost savings.
3. According to the industry to choose the material, the centrifuge can choose 304, 316 stainless steel material manufacturing, special industries can use explosion-proof motor.
4. The equipment occupies small space, convenient transportation and lifting, sometimes in order to save the space occupied by the machine and realize the centralized preparation and purification process of slurry, the device can also be placed on the containerized slurry tank, but the equipment must be provided with a solid bottom support, and provide reliable safety protection facilities for the operator. In terms of construction piling mud treatment, the mud purification equipment consists of mud feeding system, dosing system, desanding purification system, mud separator, slag discharge system, recycling mud tank and blending mud tank.
Summarize the advantages of waste plastic bag cleaning sludge treatment equipment:
Large treatment capacity, long wear-resistant service life, reasonable structure, low noise, small footprint, wide range of application, simple operation, easy maintenance, high degree of automation, smooth operation, low equipment cost, less infrastructure costs.
