Description

Technical Field

[0001] The invention relates to a sludge treatment device. Background Art

[0002] The feces and sewage removed from the septic tank need to be fermented and matured, and then converted into organic fertilizer before they can be used. Because debris will enter the septic tank, solid-liquid separation is required before the feces and sewage are fermented to intercept the debris in the feces and sewage, which is conducive to the subsequent feces and sewage fermentation and organic fertilizer utilization. The main methods of feces and sewage fermentation are aerobic fermentation and anaerobic fermentation. Aerobic fermentation uses composting technology, but the water content of feces and sewage is high and needs to be dehydrated and dried first. Composting is suitable for centralized treatment of a certain scale and is not convenient for the treatment of dispersed feces and sewage. Rural areas have land conditions, and the nearby maturation and utilization of feces and sewage is an ideal treatment and disposal method. Based on the existing technical conditions, the synchronous anaerobic stabilization treatment technology is suitable for the nearby treatment and disposal of dispersed feces and sewage in rural areas. To achieve the nearby treatment and disposal of feces and sewage, it is also necessary to intercept the debris in the feces and sewage on site to facilitate subsequent maturation and utilization. The general solid-liquid separator is not suitable for decentralized on-site application in rural areas. The use of coarse screens can intercept sewage on site, but it is also necessary to overcome the problem of a large amount of fecal water carried in the debris, and it is necessary to clean the debris in the screen in a timely manner to avoid accumulation and blockage. Therefore, it is necessary to adopt a device that has the function of intercepting debris in feces and sewage and collecting, dehydrating and infiltrating debris, which is convenient for nearby operation. In terms of feces and sewage fermentation, according to the characteristics of synchronous anaerobic stabilization treatment technology, a water diversion and flow control well is generally provided before at least two parallel septic tanks, and the flow control device is installed in the water diversion and flow control well. The parallel spacing between the water inlet pipes of two adjacent septic tanks can reach more than three meters, while the width of the water diversion and flow control well is generally only 1-1.5 meters. The part that is less than the spacing between two septic tanks needs to be buried with pipes. If the debris retention and dehydration device is installed outside the water diversion and flow control well, additional land will be occupied, increasing costs and workload. Therefore, by utilizing the distance between the water inlet pipes of two parallel septic tanks, the debris retention and collection dehydration device can be combined with the water diversion and flow control well. This can combine the debris retention and collection dehydration of manure and sewage pretreatment with the synchronous anaerobic stabilization treatment technology of manure and sewage maturation, solve the problems of debris retention, collection dehydration, seepage backflow, etc. in manure and sewage pretreatment, optimize the pretreatment of synchronous maturation of manure and sewage, and facilitate subsequent manure and sewage treatment and disposal. Summary of the invention

[0003] The purpose of the present invention is to design a synchronous maturation device for manure and sewage, which is composed of a sewage interception, collection, water distribution and flow control well trough and at least two parallel septic tanks.

[0004] The technical solution of the sewage interception and pretreatment feces and sewage maturation device of the present invention is composed of a sewage interception, collection, water diversion and flow control well trough connected to two groups of parallel septic tanks, each group of septic tanks has at least one septic tank; the sewage interception, collection, water diversion and flow control well trough described below is referred to as the well trough, and at least two water outlets are arranged at the lower part of the well trough, and the water outlets are arranged at the two ends of the well trough, and the flow cross section in front of the water outlet has a flow control device, and the bottom of the well trough is a sewage flow channel, and at least one sewage inlet interception trough and at least one debris storage and dehydration container are arranged in the upper middle part of the well trough between the flow control devices at the two ends, or at least one sewage inlet interception trough and at least one debris storage and dehydration container are arranged in the well trough. At least one sewage inlet and interception trough is provided in the middle and upper part, at least one debris collection and dehydration container is bypassed outside the trough, pipes are led out from the outlet where the flow control device is installed and are respectively connected to a septic tank, the water outlet of the septic tank is provided with a septic tank drainage pipe, or the water outlet of the septic tank is connected to a water diversion flow control well, or the water outlet of the septic tank is connected to a flow control well equipped with a flow control device by a septic tank drainage pipe; when the synchronous maturation device for sewage and feces is started, a group of flow control devices at the input end of the septic tank or at both ends of the septic tank are opened, and the flow control devices at the input ends of other septic tanks or at both ends of the septic tank are closed.

When there are many debris in the sewage, it affects the drainage speed of the sewage interception grille, and the sewage exceeds the top of the sewage interception trough, and the excess sewage overflows and is discharged into the well. After the sewage transfer input is completed, the debris intercepted by the grille is cleaned and placed in the debris storage and dehydration container. The debris storage and dehydration container has holes at the bottom. During the period when the debris stays in the storage and dehydration container, sewage seeps out and flows back into the well.

When the fermentation time reaches the feces and sewage maturation time, a batch of feces and sewage anaerobic stabilization treatment is completed and becomes mature sludge; the mature sludge is cleared out to free up the volume space of the septic tank, and the other group of septic tanks has completed feces and sewage accumulation. The flow control devices of the two groups of septic tanks are switched, and the flow control device before the septic tank with the freed space is turned on to start collecting accumulated feces and sewage, and the flow control device before the septic tank that has collected accumulated feces and sewage is turned off to restart the anaerobic stabilization treatment of a new batch of feces and sewage; they are operated in rotation in sequence.
