Description

Sludge Treatment Equipment {Management equipment of sludge}

The present invention relates to a sludge treatment apparatus for efficiently treating the nutrients, livestock manure, various factory wastewater (hereinafter referred to as "sludge") generated in daily life and livestock industry, factories, etc. The sludge separation tank is separated and configured to separate water and sludge by putting chemicals into the sludge collection truck and the collected sludge, and the sludge separation tank is fixedly formed and the sludge collection truck is moved by using a separate vehicle. By making this possible, the sludge is collected at the site where sludge is generated so that it can be treated immediately, thereby improving treatment efficiency and drastically reducing the treatment cost, and also improving the applicant's patent application No. 99-20404. will be.

In general, various methods have been proposed and widely used for treating sludge such as phosphorus, livestock manure and various plant wastewater.

The representative treatment equipment collects sludge generated at various sites in a specific septic tank, and when it reaches the full water level, it is collected by using a separate collection truck, and then moved to a place equipped with a sludge treatment facility and treated by various treatment methods. there was.

The common treatment method of sludge flows sludge together with sewage into a septic tank or a standardized treatment facility to be decomposed by bacteria during a certain period of time in the septic tank. In addition to the discharge to the treatment plant, the sewage treatment device is to be decomposed by the biological decomposition method and discharged to the outside.

However, in the case of the general sludge treatment apparatus as described above, the sludge generated in the field stays for a long time until the water level becomes high in the septic tank or the like, so that the solidification phenomenon occurs at the upper side or the side of the septic tank. In addition to being a major impediment to the collection efficiency, there was a problem of polluting the surrounding environment with a bad odor.

In particular, 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 However, there is a problem that the processing cost is high.

In the case of livestock meal, the pollution level is more severe, and there may be some differences depending on the type of livestock industry. However, in the method of processing most livestock meal, first, the manure of livestock is collected from the livestock house and moved to a separate storage place. After slaughtered, these sludges are mixed with sawdust or chaff to remove water, and when fermented naturally after a certain period of time, it is used as a fertilizer or transferred to another treatment plant for post-treatment.

However, in this case, not only is the overflow of sewage due to rainwater or other external inflow during filtration of the sludge, but also leachate is generated when it is prevented, which contaminates the river and drinking water.

In addition, wastewater purification facilities of factories have many kinds of environmentally harmful components, so there may be some differences depending on the substances produced at the factory. After separation or storage by natural sedimentation method, and after treatment using a separate device, expensive facilities and high maintenance costs are generated as well as the effect is slight.

Accordingly, in order to solve the conventional problems as described above, the applicant of the present application proposes a mobile treatment method that can separate and dispose the sludge generated on the spot without the need for a separate sludge treatment facility, the patent application 99-20404 He was elected as an arc.

Mixing step to sufficiently mix with the chemical during the passage, the separation step to completely separate the sludge and water by a plurality of filter panels in the sludge separation tank, and the discharge step of discharging the sludge and sewage separated as described above Etc.

However, in the invention of such a prior application, since the sludge treatment method consists of a single vehicle, the sludge treatment method can be moved to the site and the sludge can be disposed of immediately, and the treatment efficiency is improved by treating it with chemicals and filter panels. Even though it has an advantage to improve, there was a problem that the mobile is rather uncomfortable under the condition that a large amount of sludge is generated in one place.

An object of the present invention is to be fixed on the site so that the sludge generated in the field can be separated immediately upon collection, and the sludge by completely dehydrating the water contained in the sludge completely using the filter panel at the same time as the chemical input. It is to provide a sludge treatment apparatus to maximize the treatment efficiency.
