Comprehensive treatment method for pollution of livestock and poultry aquaculture, special feedstuff bridging agent, biological edible warm pad and biological organic fertilizer

Abstract

The invention belongs to the technical field of agricultural cultivation, which comprises a comprehensive treatment method for livestock and poultry breeding industry pollution, a special feed bridging agent, a biological edible warm pad and biological organic fertilizer; wherein, the comprehensive treatment method for livestock and poultry breeding industry pollution is realized by the steps as follows: (1) the livestock and poultry are fed by the feed bridging agent which is prepared by that probiotic bacterial flora is enlarged for cultivation and inoculated to natural organic matter for fermentation; (2) the livestock and poultry cultivation ring is padded by the biological edible warm pad which is prepared by the fermentation by matching the probiotic bacterial flora and the biological organic raw material; (3) the biological edible warm pad mixed with the dejecta of the animals is added into microbial flora so as to prepare the completely rotten biological organic fertilizer. The treatment method of the invention has the advantages that the feed is sufficiently absorbed in the animal body, the nutrition drainage is reduced, the feed is saved and the pollution is reduced; no waste gas and no waste matter are generated during the cultivation process; the pollution source is thoroughly eliminated; the pollution of the cultivation on the environment is radically solved; the dejecta of the animals is processed in situ and the organic fertilizer is produced.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry, in particular to the comprehensive treatment technology of breeding environment pollution. Background technique [0002] In recent years, my country's livestock and poultry breeding industry has developed rapidly, and its contribution rate in agricultural output value has doubled from 14% in 1970 to 30% in 2000. The development of livestock and poultry industry has led to the aggravation of breeding pollution. According to the results of pollution investigation and estimation, in 1988, the loss of livestock and poultry pollutants COD (chemical oxygen demand of water pollutants), nitrogen, and phosphorus were 4.551 million tons, 2.494 million tons, and 237,000 tons, respectively. In 2001, they were 6.896 million tons. 10,000 tons, 3.693 million tons and 297,000 tons. [0003] Judging from the land load of livestock and poultry manure, my country's overall land load warning value has rea...

Problems solved by technology

However, there are few or no non-nutritional additives to promote feed absorption, which will inevitably cause insufficient nutrient absorption (only absorb 30-50%). pollution

The pollution source is applied to the soil as a fertilizer after being dried or untreated, causing soil pollution, burning seedlings, aggravation of pests and diseases, etc.

[0007] Although the way of building a biogas digester can solve part of the excrement, the biogas residue needs to be cleaned at intervals, which may also cause secondary pollution
