Technical solution
In order to realize above-mentioned technical purpose, the utility model devises the special equipment of kitchen biogas liquor treating process, it is special Sign is:It mainly includes air flotation cell, sludge absorption pond, filter, biochemistry pool.
The raw water box is connected with air flotation cell, and intake pump is housed on connecting line, and the clear liquid output terminal of air flotation cell connects Connect sludge absorption pond, scum silica frost output terminal connection scum silica frost processing system, sludge absorption pond output terminal connection filter, filter it is defeated Outlet connects biochemistry pool, the water outlet connection tank of biochemistry pool, and the bottom of biochemistry pool is connected with sludge absorption pond, connecting line It is upper that sludge reflux pump is housed.
Further, the air flotation cell is mainly provided with flotation tank, air dissolved pump, gas-liquid separator, dross separation apparatus, scum silica frost Processing system, wherein, the bottom connection of gas-liquid separator and flotation tank, connecting line is equipped with air dissolved pump, gas-liquid separator The port of export is equipped with bubble disperser device.
Further, filtrate and water distributor are equipped with the filter.
Beneficial effect
A kind of special equipment of kitchen biogas liquor treating process of the utility model design, passes through " air supporting-sludge absorption-mistake The group technology of filter-biochemistry " removes different types of grease, suspended particulate substance, organic matter, ammonia nitrogen in kitchen biogas slurry respectively, drop Low influence of the pollutant to successive depths processing system, wherein, sludge absorption process is taken full advantage of in existing biochemical system A large amount of excess sludges of discharge, not only can reduce operating cost with oil removing, and reduce the environment that excess sludge discharge is brought Pollution, realizes the recycling of excess sludge, and the scum silica frost separated can be used as production soap and wash after processing The raw material of clothing powder, realizes the recycling of biogas slurry.
