Problems solved by technology

Among them, solid manure is more suitable for the preparation of organic fertilizers, but liquid manure has a high water content, and the existing technology cannot be processed into organic fertilizers. It can only be processed by the method of "anaerobic fermentation + aerobic aeration + biological purification pond" , there are defects such as huge investment, high energy consumption, high processing cost, and difficult processing, so it is currently impossible to promote and apply it on a large scale
The sewage of farms in our country h

Embodiment Construction

[0025] see figure 1 , There is a distance between the combined fermentation bodies of the present invention, and the distance is controlled at about 0.1 to 1 meter, so as to facilitate air to flow through the fermentation bodies. The fermentation body is installed above the liquid storage tank through a bracket, so that excess water can easily flow into the liquid storage tank from the slatted plate, so that water does not accumulate at the bottom of the fermentation body.

[0026] In order to achieve circulation treatment, the present invention is provided with a water pump and a liquid distribution pipe. A water pump is installed at the bottom of the liquid storage tank, and the water outlet end of the water pump is connected to the liquid distribution pipe. The liquid distribution pipe is arranged above the fermentation tank in the ceiling and has multiple spraying The head sprays the sewage evenly into the fermentation body.

[0027] After the liquid manure flows through ...

Abstract

The invention discloses a farm liquid manure treatment system and method. The system comprises a treatment field shed body, a plurality of fermentation bodies, a liquid storage tank for storing liquid manure, a liquid distribution pipe and a sewage pump. The invention has the technical effects that liquid manure enters each fermentation body through the sewage pump and a water distribution pipe and is quickly decomposed and digested by microorganisms in padding in each fermentation body, water is evaporated through the side wall of each fermentation body, redundant sewage falls into the liquid storage tank through a leak board at the bottom of each fermentation body and is regularly sprayed into each fermentation body through a sewage pump and the liquid distribution pipe, and the processes are circulated. Fresh air can enter each fermentation body from the periphery of each fermentation body, thereby providing sufficient oxygen for microorganism growth, carrying away vapor and promoting sewage evaporation. The number of the fermentation bodies of the system can be correspondingly increased or reduced according to the liquid manure treatment capacity, the padding does not need to be raked, the investment and operation costs are low, the operation is simple, and regularly replaced padding can be prepared into high-quality organic fertilizer.

Description

technical field [0001] The invention relates to a system and method for treating liquid manure, in particular to a system and method for treating liquid manure in farms by combining natural evaporation and fermentation. Background technique [0002] Modern aquaculture produces a large amount of manure, and improper treatment can easily cause serious environmental pollution. Farm manure can be divided into solid manure and liquid manure. Solid manure is mainly animal manure, and liquid manure is mainly composed of urine and washing. Made with water. Among them, solid manure is more suitable for the preparation of organic fertilizers, but liquid manure has a high water content, and the existing technology cannot be processed into organic fertilizers. It can only be processed by the method of "anaerobic fermentation + aerobic aeration + biological purification pond" , there are defects such as huge investment, high energy consumption, high processing cost, and high processing ...
