Problems solved by technology

[0003] The grid tank in the general wastewater treatment equipment can only intercept larger suspended solids, and cannot intercept suspended solids of different volumes separately, resulting in the accumulation of suspended solids on the front side of the grid, resulting in grid blockage, requiring staff to Multiple cleanings of suspended solids will increase the workload and intensity of the staff, reduce the efficiency of wastewater treatment, and at the same time, it is not convenient to replace the grid, and the damage of the grid will affect the normal interception of suspended solids; the wastewater from the farm has a strong odor , the general grid pool is set with an open mouth, which cannot block the spread of odor, which will cause odor to pollute the environment and affect the normal work and life of the staff
[0004] Moreover, when the grid pool is filtered, it is easy to block the grid, and because the organic suspended matter generally has a certain viscosity, it is bonded to the grid, and it is easy to cause the organic matter on the grid to be difficult to remove. The longer the adhesion, the more the filter effect of the grid will eventually be lost, especially for high-concentration organic wastewater.
At present, it is generally necessary to manually scrub the grille regularly, which is labor-intensive and has a strong odor, which has a lot of uncomfortable effects on the body

Abstract

The invention discloses harmless treatment equipment for high-concentration organic wastewater of a livestock farm. A grid tank is internally detachably provided with a plurality of grid groups whichare parallel to each other and are distributed at intervals in a clamping connection manner; the bottom of the grid tank is located between the grid groups and inner walls at two ends of the grid tank; an organic solid communication pipe communicated with an organic solid composting tank is arranged between two adjacent grids of each grid group; each grid of each grid group is provided with a material scraping assembly and a material blowing assembly, and the material scraping assembly and the material blowing assembly are located at two sides of the grid respectively; each material blowing assembly is responsible for blowing a filtered material on the corresponding grid to the side of the corresponding material scraping assembly. The grid tank provided by the invention can be used for intercepting suspension matters with different volumes, the suspension matters are prevented from being accumulated at the same position and the suspension matters with different volumes are interceptedrespectively; the number of times of cleaning the suspension matters by workers is reduced, and the working amount and working strength of the workers are reduced; blocking is prevented, a mounting frame is convenient to replace, the replacement difficulty is reduced and the replacement efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of farm wastewater treatment equipment, in particular to a harmless treatment equipment for high-concentration organic wastewater in a farm. Background technique [0002] Farm wastewater is mainly composed of urine, residual feces, feed residues and washing water. Some farms also include domestic wastewater generated during production. Farm wastewater has a high content of organic matter and a large amount of suspended solids. Purification treatment and direct discharge cause environmental pollution, so wastewater treatment equipment is required to purify wastewater to avoid environmental pollution. [0003] The grid tank in the general wastewater treatment equipment can only intercept larger suspended solids, and cannot intercept suspended solids of different volumes separately, resulting in the accumulation of suspended solids on the front side of the grid, resulting in grid blockage, requiring staff to M...
