Embodiment 1

[0023] The production process of the polyaluminum chloride: prepare polyaluminum chloride after reacting waste hydrochloric acid with calcium aluminate.

[0024] The waste oil recovery process is as follows: first filter the waste oil, then separate the oil from water, heat to 110-180°C, condense and separate the oil, and collect the waste oil residue and waste water; continue to heat to 180-350°C, then condense and collect the waste oil residue And waste water, and finally get the finished product.

[0025] The polyferric sulfate, polyaluminum chloride and waste oil recovery processes are set in the same production area, and all kinds of waste generated by the three processes are uniformly treated.

[0026] The method for joint treatment of industrial discharges is characterized in that: the method for joint treatment of waste water, waste gas, noise and fixed waste discharged by polyferric sulfate, polyaluminum chloride and waste oil recovery process; the steps are as follow...

Abstract

The invention relates to a combined treatment method for industrial emissions, and belongs to the technical field of aftertreatment. In the method, combined treatment is conducted on waste water, waste gas, noise and immobilized waste emitted by polymeric ferric sulfate, polymeric aluminum chloride and waste oil recovery processes. Compared with the prior art where independent treatment is adoptedfor the polymeric ferric sulfate, polymeric aluminum chloride and waste oil recovery processes, the method has the advantages that the three waste treatment processes are uniformly set in the same production area, and secondary industrial emissions emitted by the processes are uniformly treated, so that monitoring of the equipment working condition is facilitated, the cost is reduced, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to a method for joint treatment of industrial discharges, in particular to a method for joint treatment of industrial discharges with polyferric sulfate, polyaluminum chloride and a waste oil recovery process, and belongs to the technical field of post-treatment. Background technique [0002] The industrial production process needs to consume a lot of raw materials and energy, and it also brings a lot of pollutants while obtaining the required products. There are many kinds of industrial products, and the industrial waste produced is also different. The waste produced by industry can be divided into solid waste, liquid waste and gas waste according to the form, collectively referred to as "three wastes". Different forms of waste have different treatment methods. Treatment and disposal of industrial waste Industrial waste must also be treated and disposed of in accordance with the requirements of general waste. Because it is very ...
