Embodiment Construction

[0030] The present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments.

[0031] Raw water (before wastewater treatment) enters the reuse treatment device from the water inlet pipe, passes through the regulating tank, and is lifted by a pump into the charge coagulation reactor for electrolysis. The ferrous hydroxide produced during electrolysis has good adsorption performance and certain hydrophobicity In order to strengthen the flocculation effect of iron, two baffles are added in the charge aggregation reactor, and a channel is formed in the middle. An aeration device is installed under the channel. The mixed liquid is divided into three zones, forming a liquid circulation movement. The mixed liquid in the channel rises with the updraft sprayed by the aeration device, and then descends from the two areas on both sides of the baffle, so that it is continuously circulated. There is a set of plate groups on each ...

Abstract

The invention relates to a device for recycling and treating wastewater produced in the dismantling process of scraped vehicles. The device comprises a charge aggregation reactor; pole plate groups are arranged in the charge aggregation reactor; each pole plate group comprises a plurality of pole plates which are erected in parallel, and two pole plates which are positioned on the outmost side are connected with positive and negative electrodes of an external power; and horizontally arranged and insulated perforated plates are arranged between the pole plates. The invention also relates to a method for recycling and treating the wastewater produced in the dismantling process of scraped vehicles, and whether the wastewater flows through an oil and water separation reactor is determined according to the oil content of wastewater. The device for recycling and treating wastewater produced in the dismantling process of scraped vehicles has the advantages of effectively reducing power consumption, along with simple structure, good iron removal effect, and good aggregation effect of suspension substance, and is particularly suitable for wastewater treatment in a factory for dismantling the scraped vehicles.

Description

technical field [0001] The invention relates to a sewage treatment device and method, in particular to a recycling treatment device and method for wastewater produced in automobile dismantling plants in the manufacturing industry, and is a treatment method based on the charge coagulation method. Background technique [0002] With the continuous, stable and healthy development of the economy, the development of the automobile industry and the acceleration of automobile renewal, the number of scrapped cars is increasing year by year, and companies participating in the dismantling of scrapped cars have sprung up all over the country. By the end of December 2007, there were nearly 400 scrapped vehicle recycling and dismantling enterprises nationwide. However, due to the influence of factors such as the technical level and the quality of employees in automobile dismantling enterprises in various places, the resource waste and environmental pollution caused by dismantling scrapped...
