Abstract

INSTALLATION FOR TRANSPORTATION AND SEWAGE TREATMENT Svinokompleks comprising navozotransportiruyuschy tray pump pumping station averager with feed pumps, plant mechanically separating and connecting yuvshe their pipes, characterized in that the chain povscheni operational reliability and reduce the construction and operating costs, workshop mechanical separation and an averager with feed pumps are located between the manure-transporting tray and the pumping pumping station; in this case, the shop is connected to the tray, and averager - with pumping pumping station.

Description

The invention relates to a device for the transport and treatment of manure-containing wastewater, preferably the stop waters of pig farms and farms.

A known installation for transporting and treating wastewater of pig farms, including successively installed pig complex with manure pans, pumping pumping station, main pumping station, primary vertical from the steadfast, averager, settling centrifuge and connecting their pipelines tj.

The disadvantages of this installation are high construction and. operating costs, and low operational reliability, due to the need to transport manure from pig houses to a centrifuge and the inability to process the runoff before separating the solid fraction. At the same time, manure is capable of caking in tanks and clogging pipelines and pumps.

Closest to the proposed technical essence and the achieved result is an installation for transporting and treating wastewater of pig farms, including successive manure transporting tray, pumping pumping station, averager with feed pumps and mixing pumps, mechanical separation shop and connecting them to pipelines 2j

The disadvantages of the known installation are high construction and operating costs, as well as low operational reliability, due to the transportation of non-segregated runoff fractions, which leads to an increase in the volume of capacities and pump performance. The tendency of manure to caking necessitates its continuous barbing in the averager.

The purpose of the invention is to increase operational reliability and reduce construction and operating costs.

This goal is achieved by the fact that in an installation containing a manure-transporting tray, a pumping pumping station, an averager with feed pumps, a mechanical separation shop and pipelines connecting them, a mechanical separation shop and an averager with feed pumps are located between the manure-transporting tray and the pumping pumping station. the workshop is connected to the tray, and the averager is connected to the pumping station.

The drawing shows the proposed installation.

The installation includes a manure transporting tray 1 placed in the room of the pigsty 2 under the machines 3 for keeping pigs. Tray 1 is equipped with a self-flowing pipe 4, which connects it to workshop 5 for mechanical separation of the flow into solid and liquid fractions. Workshop 5 contains separator 6 (drum-type separator, dynamic filter, vibrating screen, etc.) and conveyor 7 to remove the solid fraction. The shop 5 is connected by means of a self-flowing pipe 8 to an averager 9, in which submersible pumps 10 are located to supply the liquid fraction to the receiving tank 11 of the pumping station 12 of the pumping station, which serves as the main pumping station. The averager 9 is connected to the pump station 12 by a pressure pipe 13. The station 12 is equipped with a pump 14, which in the pressure pipe 15 supplies the liquid fraction from the receiving tank 11 to the treatment plant site where it is deeply processed.

The installation works as follows.

The manure formed in the pigsty 2 enters the tray 1 in the slurry process. The resulting manure-containing waste water from tray 1 flows through the gravity pipeline 4 to workshop 5, where it is divided into solid and liquid fractions using the separator 6. The solid fraction from the separator 6 falls onto the conveyor 7 and is supplied, for example, to drying, and the liquid fraction is collected by the pipeline 8 and flows into the averaging unit 9, which equalizes the irregularity of its supply. Since the manure is separated from the water before it enters the averager 9, the latter is only equipped with feed pumps 10. The treatment facilities are usually located at a distance of 3-5 km from the pig houses, which prevents the use of pumps 10

for supplying wastewater, non-medium-operational reliability is resistant to cleaning. Therefore, the water is new. Separation of the solid fraction to

the averager 9, through the pressure pipe for the entry of waste water into the averaging conduit 13, is fed to the receiving choke, resulting in a reduction

 11, from where the pump 14 is the intermediate pump and the receiving tank

It draws on the pressure pipeline, pumping station and the reduction of cold oil 15 to the treatment plant. The quality of the fluid being pumped to the use of the invention by means of boosters, and allows it to prevent the construction and exclusion of blockages of pipelines and exploitation costs from being reduced and the amount of manure to be increased.
