Description

Sludge handling vehicle use sludge handle method

The present invention is a sludge treatment vehicle that efficiently treats phosphorus, livestock manure, and various plant wastewater (hereinafter referred to as 'sludge') generated in everyday life, livestock industry, and factories using a sludge treatment vehicle equipped with a sludge treatment device. It relates to a sludge treatment method using, in more detail, a specially created filter panel and vegetable polymer drugs are properly mixed to separate and dehydrate water contained in the sludge as a separation means by chemical reaction. By taking out the sludge, the sludge treatment efficiency is greatly improved, so that sludge is collected as a sludge treatment vehicle at the site where various sludges are generated. Can significantly reduce the cost of treatment and sludge treatment It was immediately treated or transported to a pure sludge treatment depending on the number of minutes to be recycled and processed separately Et solve water pollution problems must, of course, but that could seek to biryohwa of sludge.

In general, various methods for treating sludge such as serving, livestock manure, and various plant wastewaters have been proposed and widely used in the related art, and a typical treatment method of such sludge is as follows.

That is, when the sludge generated is introduced into a septic tank or a standardized treatment facility together with the sewage, it is decomposed by bacteria during a certain period of time in the septic tank and discharged to the sewage treatment plant through the drain pipe together with the sewage. In the device, it is purified by a biological decomposition method or the like and discharged to the outside.

However, in the case of the conventional sludge treatment method, the sludge stays in the septic tank or sewage treatment plant for a long time, so that coagulation occurs at the upper side and the side of the septic tank. In addition, there is a problem that it is difficult to expect the performance of the septic tank due to the solidification phenomenon in the drain pipe, and if this phenomenon is repeated, the purification ability is significantly reduced and the degree of pollution becomes serious, which is the main culprit of soil and river pollution. have.

In addition, the sludge contains a large amount of water in order to remove the moisture to leave the air for a certain period of time to remove the water or by using a separate dehydration device to dehydrate the water in the sludge, as well as waste of manpower, There is a problem that the processing cost is high.

In particular, the degree of contamination is a more serious condition in the case of livestock powder. There may be some differences depending on the type of livestock industry. However, in the method of processing most livestock powder, first, the manure of livestock is collected from the barn, moved to a separate storage area, and then piled up to the outside, and the sawdust or rice husk is applied to such sludge. The mixture was dried to remove water and, after a certain period of time, fermented naturally, used as fertilizer or transferred to another treatment plant for post-treatment.

Therefore, in this case, not only the sewage overflows due to rainwater or other external inflows while depositing the sludge in a separate container, but also if it is prevented, the leachate is generated, so as to contaminate the soil and rivers. Was to contaminate drinking water.

In addition, the plant's wastewater purification facility has many kinds of wastewater components, which are different depending on the materials produced in the plant.In general, chemicals are added depending on the type and stored in solid state for a long time according to the concentration of the dilution. After separation or natural sedimentation, the wastewater is discharged to a wastewater using a separate device, resulting in expensive facilities and high maintenance costs, as well as a slight effect.

The present invention has been proposed in order to solve the conventional problems as described above, the purpose of which is to remove the sludge generated in the field without the need for a separate sludge treatment facility to remove the treatment immediately by adopting a mobile treatment method The present invention provides a sludge treatment method using a sludge treatment vehicle and an apparatus therefor that can significantly reduce facility and treatment costs.

Another object of the present invention is to provide a sludge treatment method and apparatus using a sludge treatment vehicle to maximize the sludge throughput as well as to improve the treatment efficiency by completely dehydrating water contained in a large amount of sludge.

The present invention for achieving the above object is to mount a separate sludge treatment device in the loading of the movable vehicle to collect and collect the sludge at the site where various sludges are generated, and at the same time enable the separation treatment immediately, the sludge treatment The method comprises the steps of suctioning and collecting the sludge contained in the septic tank with a vacuum pump to separate the first milling and the contaminated material, while the second milling is carried out by the vacuum pump while transferring the sludge to the sludge separation tank. In order to fully mix with the chemical while passing through the stirrer, and to completely separate the sludge and water by a plurality of filter panels in the sludge separation tank, and to discharge the sludge and sewage separated as described above It is characterized in that the sludge is treated.
